5 Chrome Flags You Should Enable to Boost your Browsing

Google Chrome has enough features to shake a stick at, or more appropriately, to wave a flag at. One of the less-charted areas of Chrome’s broad repertoire is Chrome Flags where you’ll find a database of experimental features that, while not always fully functional, can boost your browser in ways you wouldn’t have thought possible.

These are the best Chrome Flags for tweaking the browser on both computers and mobile.

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.


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

1. Zero-Copy Rasterization (Desktop/Android)

Rasterization is the process by which Chrome organizes 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 to up to the whole you see in front of you.

Best Chrome Flags Zero Copy Rasterizer

There are a few things you can do with rasterization through Chrome flags, but one of the best is zero-copy rasterization, which can ease load on a low-end GPU by not uploading every tile change to it, offloading it instead onto your device’s memory.

This can be particularly helpful on mobile devices, with the potential to reduce battery usage when you browse the web.

2. 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.

This feature’s not for everyone, but if you want to try it then 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!

3. Enable Parallel Downloading

There are several features on 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”, then click “Default” when it appears in the list, then click “Enable”.

4. 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. In my experience 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 directly access it. Enable it using the dropdown menu below it.

5. 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 directly access it. Use the dropdown menu below it to enable it.


From the same Chrome Flags you can also enable Chrome Offline mode that allows you to access already-visited websites without the need of an Internet connection. I have written a step-by-step guide on How to enable and use offline mode in Chrome; you can check it out if you are interested.


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. These experiments can prevent you from browsing normally and may even lead to data loss, so be very careful and only enable what we have mentioned above.

Do you have any favorite flags that you’d like to see included? Let us know in the comments!

  1. Hi,

    There are several ‘top chrome flags to use in 2019’ type of articles online suggesting useful tweaks to improve browser experience…however the majority of those recommended flags do not show up in search results within chrome://flags anymore (or at least not using the same keywords, hashtags or descriptors).

    Is anyone aware of a resource that displays the most recently updated/active flags?

    Thanks for any knowledge.

    1. What’ll happen is that Google will -always- go deeper and deeper in trying to remove any-and-all user-control of their browser.. This is so that YouTube can serve ads uninterrupted and whatever. :/ It’s (very!?) unfortunate: sad, but true.. Meh! :f
