In short
GPU Information Checker is a free online tool on inputtesthub.com that reports your graphics renderer, WebGL version, shader language and texture limits — useful when a site says WebGL is unsupported. It needs no account, no download and no payment, and there is no daily usage limit. Everything is processed inside your own browser, so the data you paste is never uploaded to a server.
How to use the GPU Information Checker
- The test starts on its own — no button to press and nothing to install.
- Follow the prompt in the test panel and watch the readings update live.
- Press Reset to start over with a clean slate.
About the GPU Information Checker
The GPU Information Checker reports your graphics renderer, WebGL version, shader language and texture limits — useful when a site says WebGL is unsupported. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Confirming hardware acceleration is switched on in the browser.
- Checking which GPU a laptop with two of them is actually using.
- Diagnosing a WebGL application that will not start.
Frequently asked questions
My GPU shows as "ANGLE (Intel...)". What does that mean?
ANGLE is the translation layer Chrome and Edge use on Windows to run WebGL on top of Direct3D. The name in brackets is your real graphics adapter.
Why is the name vague?
Some browsers deliberately generalise the renderer string — Safari reports simply "Apple GPU" — to reduce fingerprinting. That is privacy protection, not a detection failure.
My laptop has two GPUs. Which is this?
Whichever one the browser is currently using, which on many laptops is the low-power integrated chip. Forcing the browser onto the discrete GPU in the graphics driver settings changes what appears here.
Is the GPU Information Checker free?
It is free, with no account, no trial and no daily cap. Every device tests tool on inputtesthub.com works the same way: open the page and use it.
Is my data uploaded anywhere?
No. The GPU Information Checker runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
Who is the GPU Information Checker for?
The most common reasons people reach for it: confirming hardware acceleration is switched on in the browser. Checking which GPU a laptop with two of them is actually using. Diagnosing a WebGL application that will not start. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Do I need to install anything to run this test?
No installation, no extension and no driver. The GPU Information Checker uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
