11 Chrome Flags You Should Enable to Boost Your Browsing

Best Chrome Flags Featured

Chrome Flags come and go at a rapid rate, with some becoming fully-fledged browser features while others disappear forever. These features have been aptly renamed to “Experiments” by Google because they let you enable, disable and customize various features that are yet to make it into the mainline Chrome release.

Some Chrome flags are semi-functional, others are obscure things designed for the highly tech-savvy, while there are some that don’t really do much at all. So we’ve sifted through the crowd and picked out the Chrome flags that will actually have a big and positive impact on your browsing experience.

Note: we update this list regularly to ensure that the flags we list are still available, but sometimes an outdated flag may slip through the net.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 Chrome Flags

Before you use any of these Chrome flags, you first need to know how to access them. Type chrome://flags in the Chrome address bar and hit Enter. You will see a big list of Chrome Flags with a warning that these features are not stable.

chrome-flags-how-to-access

You can use Chrome’s “Find” (Ctrl + F) feature to quickly find the features we have listed below.

1. Tab Groups Collapse Freezing

Tab groups are now an increasingly-used feature in the stable version of Chrome, allowing you to bundle related tabs together by color-coding them or even marking them with emojis! Another feature automatically suspends inactive tabs to save memory.

Best Chrome Flags Tab Groups Collapse Freezing

This experimental flag combines the two, letting you suspend all the tabs in a tab group when that group has been collapsed.

To enable it, search for “tab groups collapse freezing” on the Chrome Flags page.

2. Tab Groups Auto Create

Yes, tab groups are all the rage at the moment, and we’re celebrating that by giving you more flags related to tab groups. This interesting flag will automatically create tab groups for you based on your usage, automatically assigning them colors and organizing your oft-used sites into them.

Best Chrome Flags Tab Groups Auto Create

You can still manually add tabs into the auto-created groups, so it’s not like you’re completely giving up control over your tab organization here.

To enable this flag, search for “tab groups auto create,” enable it, and restart your browser.

3. Heavy Ad Intervention

Intrusive adverts are both the bane of the Internet but also, unfortunately, its life force. By default, Chrome does a so-so job of blocking ads for you (unless they’re Google ads, in which case it’s open season!), but you can enable this flag to bolster Chrome’s ad-blocking defenses.

Best Chrome Flags Heavy Ad Intervention 1

Search for “heavy ad intervention” in Chrome flags and enable it when you find it. This flag will hone in on ads that use too many system resources, automatic ad videos, and more, blocking them from your browser.

4. Force Dark Mode

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.

Best Chrome Flags Force Dark Mode

Find “force dark mode” in Chrome flags, then click the drop-down menu next to it.

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

5. Reader Mode

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.

Best Chrome Flags Reader Mode 1

Find “reader mode” in Flags, enable it, and 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.

6. GPU Rasterization

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

Best Chrome Flags Gpu Rasterization 1

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 “GPU rasterization” 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.

7. Zero-Copy Rasterization (Desktop/Android)

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.

8. Chrome Duet (Android)

On Android, Google has been experimenting with a “Duet” interface for a few years now, which places most of the options like tabs, search, home, and the options menu at the bottom of the screen instead of the top.

Best Chrome Flags Chrome Duel

This feature’s not for everyone, but if you want to try it, search for “Chrome Duet” in Chrome flags.

Here’s the strange thing: setting Chrome Duet to “Disabled” actually seems to enable it for us, while setting it to “Enabled” disables it. So if it doesn’t work, try doing the reverse of what you think you should do!

These are just some of the Chrome flags that will enhance your browsing experience. Although there are dozens of other flags to try, we do not recommend you mess with them unless you know exactly what you are doing.

9. Enable Parallel Downloading

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.

Best Chrome Flags Parallel Downloading

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

10. Enable Smooth Scrolling

As the name suggests, this lets you smoothly scroll through the 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 content and easily read what is important at the same time (bad for content skimmers). With this option enabled, smooth scrolling just feels right and professional.

Best Chrome Flags Smooth Scrolling

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 below it.

11. Enable Experimental QUIC Protocol

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 at the same time. 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. QUIC protocol’s main goal is to only make a single trip to create a connection and start the data exchange process, thus increasing the overall browsing and data exchange speed.

Best Chrome Flags Experimental Quic Protocol

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