Mouse Test (Buttons & Scroll) When To Use
Open Mouse Test (Buttons & Scroll) when you need a quick check that left, middle, and right clicks register, or that the scroll wheel still reports movement - without installing a desktop utility.
When it fits
A new mouse feels wrong on one button. A laptop trackpad click is flaky. You want to confirm wheel direction before a long editing session. You prefer an in-tab check so no driver pack or account is required.
What to expect
Enable listening, move and click on the pad, and read coordinates plus button and wheel counters. Reset clears the session. Nothing is uploaded.
For the exact clicks, see the step-by-step guide.
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
