Are You Getting The Most From Your Browser With HTTP/2?


HTTP/2 protocolWeb site addresses all begin with http or https. This indicates that they use the Hypertext Transport Protocol, which is the way that web browsers communicate with web servers. Not to be confused with HTML, which is the language used to create web pages themselves.

The HTTP specification has been stuck at version 1.1 for the past 15 years or so, but the new version 2 is now rapidly becoming popular. As well as the additional features that it offers for developers, it also includes some significant speed improvements. So if you're viewing a web site that supports version 2, from a browser that also supports it, you'll see those speed increases.

But how to find out whether your web browser supports HTTP/2? Thankfully there's an easy way. Just go to to find out. Not only will the page automatically check whether your browser supports HTTP/2, it'll also demonstrate the speed increase. It does this by downloading a set of images, using both version 1 and 2, and shows you the time that each version took to download.

So try the page, and consider changing or updating your browser if it doesn't support HTTP version 2.

Opera is also supported.

On my Win 8.1 box, HTTP2 is NOT supported on IE 11.0.9600.18321, which should be the current version. Happily, I virtually never use IE. I just wanted to see how it would do on this test.

Excellent article. I use Chrome to stay current, these short concise articles are why I donate every so often to this site. I hope more readers do also.

Thank you wanderinwoodsman, we appreciate your support. :) MC - Site Manager.

Just tried the current versions of Firefox and Internet Explorer. They both work, too.

Thanks Rob!
Glad to know Chrome supports HTTP/2.
