Key Takeaways

To test out Google Chrome's beta features, enter "chrome://flags" into the address bar, search for the flag you want, and set it to "Enabled." You’ll need to relaunch Google Chrome for the changes to take effect.

The Google Chrome browser has tons of great features, but many of them are not available by default. Chrome "flags" can enable experimental and beta features if you know where to find them. It's surprisingly easy to do.

Google will often put features behind flags before they are ready for prime time. Sometimes these features make their way to stable releases , but they can also disappear without warning. That's the nature of using experimental and beta features.

There are flags available for different platforms as well. For example, there are certain flags for Chrome on Android, Chrome on Windows, etc. The process for enabling these flags is very simple.

These features are not available to everyone for a reason. They may not work correctly and they can negatively impact your browser's performance. Enable flags at your own risk.

First, open the Chrome browser on your computer, smartphone, or tablet. Flags are available for Chrome on almost every platform, including Windows, Mac, Linux, iPhone, iPad, and Android.

 in the address bar and hit enter.

You will now be on a page titled "Experimental." It's divided into two columns: Available and Unavailable. You can scroll through the "Available" list or search for a specific flag.

When you find a flag to turn on, select the drop-down menu (It will usually say "Default.") and choose "Enabled."

After enabling a flag, you'll need to restart the browser to apply the change. You can enable multiple flags before relaunching. Select the blue "Relaunch" button when you're ready.

That's all there is to it. You've entered a larger world of browser customization. Now go out there and test out potentially upcoming Chrome features!

Testing new ways to explore and share through Chrome

Aug 31, 2021

[[read-time]] min read

When we work on new features for Chrome, we rely on feedback from the millions of people who use it every day. Hearing from people helps us build better features for them. And test builds , like Beta channel of Chrome , are some of the best ways for us to get input on new features, so we can fine-tune them before they are released. 

Flags and experiments in Chrome Beta let you choose which in-development features you want to test out before they hit the main stage. With our latest Chrome Beta release, you can try out some upcoming features that can help you more easily explore, keep track of, and share the things you find on the web.

Get things done faster with cards on the New Tab Page

Looking for that taxes spreadsheet you opened yesterday, but don’t want to spend time searching through your history? We’re starting to roll out cards on the New Tab Page that help you pick up where you left off based on your browsing history if you are signed into Chrome. The cards make it easy to revisit past activities or tasks, like planning a meal, shopping for a gift or working on a document in Google Drive. Try the feature by enabling the #ntp-modules flag on your computer. Here are a few ways they’ll show up:

• Recipes (#ntp-recipe-tasks-module): Find recently-visited and related recipes when you open a new tab, so you can rediscover that delicious-looking marinara recipe, and others like it.
• Shopping Cart (#ntp-chrome-cart-module): Don’t lose that deal — pick up on your shopping right where you left off. When you step away or browse on other sites, you can jump back into your open carts just by opening a new tab.
• Docs (#ntp-drive-module): Cards on the New Tab Page can help you find your way back to recent documents you’ve opened in Google Drive. They can also help you find relevant docs recently edited by collaborators, so it’s easy to cross things off your to-do list. 

Keep searching without needing to hit the back button

When you’re looking something up in Google Search, sometimes it takes navigating to more than one page to find exactly what you are looking for. To make it easier to navigate from one search result to the next in Chrome, we’re experimenting with adding a row beneath the address bar on Chrome for Android that shows the rest of the search results so you can get to the next result without having to go back. You can try this yourself in Chrome Beta by enabling the #continuous-search flag on Android.

Highlight and share quotes from the web

Want to share an interesting tidbit from an article you’re reading? It’s easy to do so with quote cards in Chrome. We’re starting to roll out a new experiment on Android that allows you to create a stylized image from interesting text you find on websites. You can copy these images for yourself or share them with others. Give it a go by enabling the #webnotes-stylize flag on your Android phone or tablet. Once enabled, when you visit a website, just long press a piece of text to highlight it, tap Share, and select a template by tapping “Create card” from the menu.

Testing these features and getting a better understanding of how you use them will help us optimize these tools for everyone. So if you’re someone who likes to kick the tires and try out new features, just download Chrome Beta , type chrome://flags into your address bar (or click on the Experiments beaker icon), and enable flags to start testing today. And please share your feedback — you can find more details on how to do that on our Support page .

11 Chrome Flags to Boost Your Browsing

Chrome Flags come and go at a rapid rate, with some becoming full-fledged browser features while others disappear forever. These features have been aptly renamed to “Experiments,” as they let you experiment and test beta features. There are plenty of Chrome Flags you can set to boost your browser performances. These are the best current Chrome Flags you should enable right now.

Note: we update this list regularly to ensure that the flags we list are still available, but sometimes an outdated flag may slip through the net. If that happens, then let us know in the comments, and we’ll remove it.

How to Access and Enable Chrome Flags

1. disable system notifications, 2. quiet permission chip, 3. force dark mode, 4. reader mode, 5. gpu rasterization, 6. zero-copy rasterization (desktop/android), 7. enable parallel downloading, 8. enable smooth scrolling, 9. enable experimental quic protocol, 10. enable incognito screenshot, 11. enable web feed, frequently asked questions.

Follow these steps to view and enable Chrome flags:

• Type chrome://flags in the Chrome address bar and hit Enter .
• You will see a list of Chrome Flags with a warning that the features are not stable.
• Use the search bar at the top to find the desired flag. Once you find it, click on the drop-down box next to it to enable or disable the flag.

4. Click on the “Relaunch” button to restart Chrome and activate or deactivate the flag.

Helpful hint: if you’re considering using Incognito Mode, first read about the truth behind private browsing and Incognito Mode .

There are two types of notifications that Chrome can send to your PC: some are native within Chrome, and will only appear when Chrome is running, others link to your OS and will appear within the OS UI.

A lot of people find these notifications annoying, so you may want to disable them in Chrome Flags.

In the Flags search box, type “system notifications”, then when it appears, set “Enable system notifications” to “Disabled”. No more interruptions!

Tip: Learn how to customize Chrome like a pro.

Make no mistake, the permissions notification in browsers is super-important, asking you whether you’re happy for a given site to have access to your location, microphone, and whatever else.

But the notification in Chrome has always been a bit ugly and intrusive. This flag addresses that issue by integrating the permissions box into the search bar. It’s nice and clear with a bright blue background, so there’s no chance you’ll miss it, while not taking up your browsing screen space.

To enable this flag, type “quiet permission” into the Flags search bar and enable the Quiet Permission Chip Experiment.

Tip: if you’re looking to take away some of your grunt work, check out these Chrome extensions that automate boring browsing tasks .

Dark mode is the thing that everyone’s after right now, making your screen much less strenuous on the eyes when you use it in the evenings or in a dark environment. You can make window borders darker using your OS settings, but to actually make entire web pages dark, you’ll need to enable this flag.

Find “dark mode” in Chrome flags, then click the drop-down menu next to “Auto Dark Mode for Web Contents.”

You’ll see that you have many different variants of dark mode to choose from. You can experiment with these different Dark Mode variants to see which works best or just select “Enabled” for the default option.

Tip: are you looking to space things differently on your monitor? Learn how to get vertical tabs in Chrome .

While Microsoft’s twist on a Chromium-based browser now includes a reader mode clickable from the URL bar, Google Chrome is yet to have it as a default feature. However, a quick tweak in Chrome Flags, and you can add an “Immersive Reader” mode to your omnibox. Search for “reader mode” in Flags, then turn on the Enable Reader Mode flag.

An icon will appear in your address bar. Click it to turn that page into “Immersive reader mode. You can then click the “A” icon at the top of the page to change your reader settings.

Chrome doesn’t rely too much on your GPU to process images and data, but if you have a dedicated GPU, there are a few things you can do to offload some of the processing onto it, speeding up the browser.

Rasterization is the process Chrome uses to organize website data into the pixels and tangible information you end up seeing on the screen in front of you. It does this by organizing each page into “Tiles,” at which point it effectively paints in the information in each one to add up to the whole you see in front of you.

Enabling the “GPU rasterization” flag gets your GPU to always do the above process instead of your CPU (or processor). This can make browsing faster if your CPU isn’t particularly powerful or, conversely, if your GPU is very powerful.

Helpful hint: do you find it hard to concentrate on your work when the fun of the Web is pulling you in? Learn how to block websites on Chrome .

There are a few things you can do with rasterization through Chrome flags, but one of the best is zero-copy rasterization, where writers raster streams straight to your GPU memory (or VRAM), which can work faster than using your regular RAM (particularly if you have 4GB or less RAM on your PC).

This can be particularly helpful on mobile devices, with the potential to reduce battery usage when you browse the Web. Search for “Zero-copy rasterizer,” then enable it.

There are several features of Chrome Flags that can speed up your browsing, many of which are enabled by default. One such feature, which specifically speeds up your downloads, is “Parallel downloading,” which splits each file you download into three separate jobs, speeding up the whole process.

To enable it in Chrome flags, type “parallel downloading,” click “Default” when it appears in the list, then click “Enable.”

Tip: check out the best extensions to speed up Chrome.

As the name suggests, this lets you smoothly scroll through content. When you scroll in Chrome using your mouse or the arrow keys, there is a little stuttering in the animation. This makes it hard to quickly go through the content while also reading what is important (which is bad for content skimmers). With this option enabled, smooth scrolling just feels right and professional.

Just search for “Smooth Scrolling” or type chrome://flags/#smooth-scrolling into the address bar to access it directly. Enable it using the drop-down menu.

QUIC protocol is a new connection protocol created by Google that is still under development. QUIC is supposed to be a mixture of TCP and UDP protocols that is much faster and more secure. Usually, when we are on a TCP or UDP connection, it takes multiple trips to the server before a connection is stable (which takes time) and ready to exchange data. The main goal with QUIC protocol is to make a single trip to create a connection and start the data exchange process, thus increasing the overall browsing and data exchange speed.

In Chrome, you can enable QUIC protocol to start taking advantage of this protocol and speed up browsing. Look for the “Experimental QUIC protocol” flag or type chrome://flags/#enable-quic to access it directly. Use the drop-down menu below it to enable it.

Tip: looking to take notes while you’re browsing on Chrome? Check out these Chrome extensions that will allow you to annotate text .

For privacy reasons, you cannot take screenshots with your phone while in Incognito mode in Chrome. However, enabling the Incognito screenshot flag allows you to take screenshots in Incognito mode as well.

Look for the Incognito Screenshot flag and select Enable in the drop-down box.

This flag enables the Following feed on the “ew tab page of the Chrome browser on Android phones. Under the Following feed, you will see articles from the websites that you have subscribed to.

To enable the web feed, search for the “Web feed” flag and enable it.

Once enabled, relaunch the Chrome browser, then open the website that has posts that you want listed on the New tab page of Chrome. Tap the three-dot icon at the top and Select “Follow” next to the website’s name. Follow other websites in the same manner.

Open a new tab page to find the “Following” tab right next to “Discovery.” Articles from the websites you are following will be listed below.

Tip: Would you like to have your extensions more accessible? Learn how to pin extensions to the Google Chrome toolbar .

Is it possible to reset a Chrome flag to the default value?

To reset a single flag, you must search for it in chrome://flags, then click on the drop-down box next to the flag. Choose “Default” from the list. To reset all of the Chrome flags to default values, open chrome://flags and click on the “Reset All” button at the top.

Can I use Chrome flags on my mobile?

Yes, you can experiment with beta features by using Chrome flags on both Android and iPhone. Check out the best Chrome flags for Android .

How to use Google's 'Chrome Labs' to test new browser features

Lawrence abrams.

• March 7, 2021

Google has added a new feature to Google Chrome Canary that makes it easier for users to test new hidden features under development.

When Google creates a new browser feature, it is first tested in Google Chrome Canary and Google Chrome Beta. In many cases, these new features must first be enabled using an 'experiments' configuration flag before they are accessible.

To access these experiment flags, users can go to  chrome://flags  in the address bar, which will open an 'Experiments' page with all the hidden Chrome features that can be enabled.

However, the 'Experiments' page contains many options that are not for user-facing features but instead internal tests conducted by the Chrome development team.

Due to this, it can get confusing to find new user-facing features that Google is actively developing.

Chrome Labs makes it easier to find new features

To make it easier for Google Chrome users to find new features that Google wants them to test and provide feedback on, Google has introduced this week a feature called 'Chrome Labs.'

The hidden features currently promoted by Chrome Labs are 'Reading List', 'Tab Scrolling', and 'Tab Search.' 

Users can enable these features by clicking on the 'Default' button and changing it to 'Enabled.' Once you do so, Chrome will prompt you to restart the browser to enable the feature.

Google Chrome's Head of Design Alex Ainslie announced the new Chrome Labs feature on Twitter this week and said it is available in Google Canary and coming soon to Chrome Dev and Beta.

We hope to gather more feedback about @googlechrome updates as they're in development. If you're using Canary today (and soon Dev and Beta) you'll notice a little beaker on the toolbar that makes it easier to try out new stuff and share suggestions about how it should evolve. pic.twitter.com/doPLzJbnRW — Alex Ainslie (@alexainslie) March 5, 2021

In our tests, the feature has not gone live in Google Chrome Canary as of yet, so it may still be rolling out to users.

For those who want to try it immediately, you can enable the 'Chrome Labs' feature now in Chrome Canary and Chrome Beta by entering  chrome://flags#chrome-labs in the address bar and pressing enter.

When Chrome Labs appears, change it to Enabled and restart the browser for the feature to become active.

How To Enable Flags In Google Chrome: A Step-By-Step Guide

Google Chrome, like other major web browsers , rolls out new features frequently. And there is a way to get a sneak peek at the latest features in your Chrome browser or test out experimental functionalities before they become mainstream –- through flags.

Chrome flags are experimental features and settings that you can use to access and test new functionalities. Their purpose is to allow users to try out features that are still in development or undergoing testing before they are officially rolled out as stable features in the browser. The Chrome development team uses flags to introduce and gather feedback on new features, optimizations, or changes to the browser's behavior.

Below we explain how you can enable flags in Chrome to try out upcoming features. It's important to note that experimental features enabled through flags may not be fully polished, and they might have bugs or issues. If you set up flags, you should exercise caution and be aware that there are potential risks.

Are Chrome flags safe to enable and use?

When considering whether to enable Chrome flags, it's crucial to be mindful of the risks associated with them.

Firstly, understand that Chrome flags are experimental features still in development. As such, they may not be as stable or reliable as standard browser features. Additionally, these options may not undergo the same thorough security testing as stable features, meaning your browser could be more susceptible to vulnerabilities. If you handle sensitive information online, trying out experimental features might not be the best option.

In some cases, flags can also bring about website compatibility issues as well as interfere with the proper functioning of the browser. This can result in the loss of bookmarks, browsing history, or other saved data.

Lastly, Chrome flags are subject to frequent updates and changes. The experimental features you enable today may be modified, moved, or removed in browser updates. This can lead to inconsistencies and unexpected behavior if you come to rely on flags for your browsing preferences. If you're uncertain or uncomfortable with the potential downsides, it might be best to stick with the stable, default settings of the browser.

How to enable flags in Chrome

Enabling flags in Chrome is straightforward. However, before you proceed, it is best to check for documentation or community feedback related to the specific flags you intend to enable. Experiences, tips, and potential issues shared by users on online forums can provide valuable insights into the stability and compatibility of certain experimental features.

If you want to enable multiple flags, adopt a selective approach. Enable one, assess their impact on your browsing experience, and gradually incorporate additional flags based on your observations. We also recommend backing up browser data like  saving and transferring bookmarks before enabling Chrome flags. This will ensure that in case of unexpected issues or data loss, you have a recent backup to restore your preferences, bookmarks, and other essential information.

To enable flags in Chrome:

• Launch Chrome and enter chrome://flags/ in the address bar.
• Click Enter.
• In the Available tab, look for the flag you want to enable.
• Expand its dropdown and choose Enabled. Do the same for all the other flags you want to enable.
• Once done, click Relaunch.

To disable Chrome flags, expand the dropdown for the targeted flag and choose Disabled. Alternatively, click on the Reset all button and select Relaunch. This will simultaneously disable all the flags.

Best flags to enable in Chrome

If you want to try out the flags feature but aren't sure which flags to enable, below are some common Chrome flags that users have found useful. You can also create a temporary user profile on Chrome to see if they are compatible with your browser version.

• Smooth Scrolling : This flag is designed to enhance the scrolling experience when navigating web pages. When this flag is enabled, it modifies the default scrolling behavior, making it smoother and more visually appealing. You can enable it by heading over to "chrome://flags/#smooth-scrolling" in Chrome.
• Parallel downloading : This flag divides your downloads into multiple chunks to speed up the downloading process. The files are downloaded in parallel, faster than the usual time. You can enable it by heading over to "chrome://flags/#enable-parallel-downloading" in Chrome.
• Auto Dark Mode : Dark mode is easier on the eyes of a lot of users, especially in low-light conditions. This flag forces a dark theme on all web pages, even if they don't support it natively. You can enable it by heading over to "chrome://flags/#enable-force-dark" in Chrome.

Remember that while these flags are commonly recommended, they are still experimental, and their effectiveness may vary. Additionally, the availability of flags can change with browser updates.

What are Chrome flags?

Chrome flags are a way to activate browser features that are not available by default.

For example, Chrome wanted to allow users to try picture-in-picture video features, before rolling it out to everyone.

The feature was made available behind a flag, so any user could try it out and give feedback. The code and design were tested and polished based on the feedback. Now, you can use picture-in-picture by default in Chrome, and it works really well.

Understand the risks

Most Chrome users never need to use Chrome flags .

If you do set Chrome flags, be careful. When activating or deactivating features, you could lose data or compromise your security or privacy. Features you toggle with a flag may stop working or be removed without notice.

If you're an enterprise IT administrator, you shouldn't use Chrome flags in production. Take a look at enterprise policies instead.

...and proceed with caution

Having said all that, if you're a web developer who needs to try out new technology—or just a curious geek—then getting to know Chrome flags can be really worthwhile.

There are a large number of flags for many different types of features. Some flags affect the way Chrome looks or works, and some activate features such as new JavaScript APIs. The availability of flags depends on which version of Chrome you're running.

There are two ways to set Chrome flags:

• From the chrome://flags page.
• By opening Chrome from the command line in a terminal.

chrome://flags

To set a flag from the chrome://flags page in Chrome, you need to find the flag, toggle the setting for the flag, then relaunch the browser. For example, to activate Chrome's heads-up display for performance metrics:

Now you can use the heads-up display that shows technical information about web page performance.

Command-line flags

If you're a web developer, you may want to set flags by opening Chrome from the command line. You run the command to open Chrome and add the flags you want to set. There are more Chrome settings you can configure from the command line than what's available on chrome://flags .

For example, to run Chrome Canary from a terminal on a Mac, with the Topics API activated and epoch length set to 15 seconds, use the following command:

There are hundreds of other flags for activating, deactivating and configuring less well-known features.

If you regularly use different Chrome channels with command-line flags, you may want to create a function for each channel, and add these to your shell RC file. For example, on macOS:

• Open a terminal.
• Create a function: cf(){ open -a 'Google Chrome Canary' --args $*; }
• Use the function: cf --enable-features=TrackingProtection3pcd

Set the Chrome user data directory

In Chrome engineering language, Chrome user refers to an individual human user of Chrome.

A Chrome client refers to an individual installation of Chrome on a device.

More precisely, a Chrome client corresponds to an individual user data directory . Each Chrome profile is stored in a subdirectory within the user data directory.

If you run Chrome from the command line, you can set the user data directory with the --user-data-dir flag .

That means you can have a separate user data directory for development, with its own profile subdirectories. Creating a new user data directory makes Chrome behave as if it had been freshly installed, which can be helpful for debugging profile-related issues.

To run Chrome from the command line with a new temporary user directory, use the following flag:

You might also want to add the following flags to avoid the browser check and first run UI:

Beware of flag conflicts

Flags you set may conflict with each other. chrome://flags settings override command-line settings for the same flag, and the defaults for a chrome://flags setting might, in some cases, override your command line configurations. If the flags you set running Chrome from the command line don't work as expected, you should check your chrome://flags page.

chrome://flags doesn't reflect flags set from the command line. Instead, look at the chrome://version page. The Command Line section shows flag settings.

Two other ways to try out experimental features

You can enable a range of experimental features that don't have their own flag, by toggling the chrome://flags#enable-experimental-web-platform-features flag. Documentation for new features will explain when this is an option.

In Chrome Beta you can try out featured experiments and give feedback, by toggling Experiment settings and relaunching the browser. Test experimental features in Chrome provides more detail.

Which features get a flag?

Not all experimental features get their own Chrome flag:

• Some features only become available when they ship in Chrome Canary, and can't be activated by a flag before that. This is quite rare.
• For 'smaller' features that require no more than 1–2 quarters of work, experimental availability is provided by enabling the following flag: chrome://flags#enable-experimental-web-platform-features This activates multiple minor features.
• Major features are made available for experimentation with flags specific to the feature, using chrome://flags or command line switches.

What about Chrome settings?

Chrome settings and Chrome flags serve different purposes.

Chrome flags enable the user to activate or deactivate experimental features, whereas the selections in chrome://settings allow the user to customize their experience for default features.

What about origin trials?

Origin trials are a way for developers to test a new or experimental web platform feature at scale. Developers can give feedback to the web standards community before the feature could be made available to all users.

Features undergoing an origin trial are activated on all pages that provide a valid token for that trial. This allows website owners to activate an experimental feature for all their users, without requiring users to change browser settings or set flags. By comparison, Chrome flags allow individual users to activate or deactivate an experimental feature, on all websites they visit.
