Screen Recorder

What it's for

Record what’s on your screen, in one window or in a browser tab, to show a bug, explain how to do something or keep a copy of a presentation, without installing anything. The recording is made by your browser and saved to your computer; it’s never uploaded, and there’s no watermark or time limit.

For example, when you’re reporting a bug that’s hard to describe, record the tab while you make it happen and save it as a GIF small enough to paste into the issue.

How to use it

Choose the Format (MP4 where the browser can record it, which Safari and recent Chrome can; otherwise WebM) and the Frames a second, and tick Record my microphone or Record the sound of the tab or screen if you want sound. Choose Start recording: the browser asks which screen, window or tab to share, and for the microphone if you ticked it. A timer shows while it records.

Choose Stop, or the browser’s own Stop sharing button, and the recording plays below. Save the video saves it with the date and time in its name. As a GIF makes a GIF of the whole recording at the frames a second and width you choose. All the settings are remembered.

Example

Tick Record my microphone, choose Start recording and pick a browser tab. Talk for ten seconds while scrolling, then choose Stop. The message says how long it was, its format and size; play it back below and choose Save the video.

Good to know

Screen recording needs a desktop browser: phones and tablets can’t do it in any browser. On a Mac, the browser needs Screen Recording permission in System Settings › Privacy & Security the first time. The sound of the screen can be recorded only for a tab in Chrome and Edge, or the whole screen on Windows; Safari and Firefox don’t offer it. Long recordings use a lot of memory, as they’re kept in the browser until you save them. WebM files from browsers don’t record their length, so some players can’t show it; Video Info will say so. GIFs stop at 600 frames.
