Screen Recorder

Record your screen, a single window or a browser tab — with system sound and your voice. Nothing is uploaded: the video is made in your browser and saved straight to your computer.

Smaller files that are easy to send. Right for demos, bug reports and walkthroughs.

Adds a commentary track on top of whatever sound the screen itself makes. Your browser asks for permission once.

Your screen appears here once you start. The browser will ask which screen, window or tab to share.

Recorded and saved on your device only.

How to Record Your Screen in the Browser

A screen recorder that is just a web page: no install, no account, no upload. Your browser does the capturing and the encoding, and the finished video goes straight to your downloads folder.

What gets recorded

When you press start, the browser asks what to share: your whole screen, one application window, or a single browser tab. Only what you pick is captured — the rest of your desktop, your other tabs and your notifications stay out of the video.

System and tab sound

The sharing window has a checkbox for sound — "Share tab audio" for a tab, "Share system audio" for the whole screen. Tick it and the video keeps what your computer is playing. Chrome and Edge on Windows can take the whole system's output; on macOS only tab sound comes through, and Firefox and Safari do not offer it at all.

Adding your voice

Turn the microphone on before you start and your commentary is mixed into the same track as the screen's own sound, so the recording plays back as one video everywhere. For a voice-over on a silent screen, simply leave the audio checkbox unticked in the sharing window.

The file you get

Recordings are saved as WebM, the format browsers encode natively. It plays in any modern browser, in VLC, and on YouTube, Google Drive and Discord as it is. For an editor that insists on MP4, converting a WebM is a one-step job in any free converter.

Nothing leaves your computer

There is no upload and no server involved. The video is built in your browser's memory and written to disk when you press download — which is also why a very long take eventually uses a lot of RAM, and why closing the tab loses a recording that was never saved.

Frequently asked questions

Yes. No account, no trial, no watermark, and no limit on how long or how often you record. Everything happens in your own browser, so there is nothing here to sell you.
It records two kinds. The sound your computer plays comes from the checkbox in the browser's sharing window — "Share tab audio" or "Share system audio". Your voice comes from the microphone switch on this page. Turn on both and they are mixed into a single track.
macOS does not let a browser capture the whole system's output. Chrome and Edge can still record the sound of one browser tab: pick a tab in the sharing window and tick "Share tab audio". For the sound of a native app you need a virtual audio device such as BlackHole.
iPhones and iPads have no screen capture in any browser, Chrome included — use the recorder in Control Center. Chrome for Android does not offer it either. On a phone, the recorder built into the system is the better tool.
There is no time limit here, but the video is held in the tab's memory until you download it, so a very long take can slow the browser down or run out of RAM. For anything past an hour, record in parts and download each one as you finish it.
A WebM file with VP9 video — the format browsers encode by themselves. YouTube, Google Drive, Discord, VLC and every modern browser play it as it is. If an editor demands MP4, convert it with a free tool such as HandBrake.
Nowhere, until you press download: it lives in the browser tab's memory. Downloading puts it in your usual downloads folder. Closing or reloading the tab before that loses the take, so download it first and tidy up after.
No. Nothing is sent to us or to anyone else — the capture, the encoding and the file all stay on your computer. You can prove it by recording with your network disconnected.
