In short
Screen Recorder is a free online tool on inputtesthub.com that records your screen, a window or a browser tab straight to a file, with no extension, no account and no upload. 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 Screen Recorder
- 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 Screen Recorder
The Screen Recorder records your screen, a window or a browser tab straight to a file, with no extension, no account and no upload. 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
- Recording a quick bug report or how-to.
- Capturing something on screen without installing software.
- Recording a call or presentation you are running.
Recording is done by your browser, so the length limit is memory rather than time. For long sessions, record in chunks — a browser tab holding a multi-gigabyte recording will eventually run out of room.
Frequently asked questions
Can this record without me knowing?
No, and the browser enforces that. You must pick the screen, window or tab yourself in a dialog the page cannot control, and the browser shows its own sharing indicator for as long as it lasts. A web page has no way to start a recording silently.
Is the recording uploaded?
No. It is assembled in memory in this tab and stays there until you press Download. Leaving the page discards it.
Why is there no sound?
System audio capture is limited by design. On Windows you can tick "Share tab audio" or "Share system audio" in the picker; on macOS the browser cannot capture system audio at all without extra software. Microphone audio is a separate permission.
What format do I get?
WebM in most browsers, which plays in any modern browser and uploads fine to every major platform. Use the Video Converter on this site if you need MP4.
Does the Screen Recorder cost anything?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Is what I paste into the Screen Recorder stored?
No. The Screen Recorder runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
What do people use the Screen Recorder for most?
In practice it gets used for three things: recording a quick bug report or how-to. Capturing something on screen without installing software. Recording a call or presentation you are running. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Any caveats I should know about?
Recording is done by your browser, so the length limit is memory rather than time. For long sessions, record in chunks — a browser tab holding a multi-gigabyte recording will eventually run out of room.
Why does the test start on its own?
No installation, no extension and no driver. The Screen Recorder 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.
