Online screen recorder

The recorder uses the screen-sharing feature built into desktop browsers. When you start, the browser asks what to share:

• Entire screen: everything, including other apps and notifications.
• A window: one app, such as a slide deck or a spreadsheet.
• A browser tab: just that tab, often with its sound.

The page can't see your screen until you pick something and confirm. Stop with the Stop button or the browser's own Stop sharing bar. You can watch the video on the page before downloading it.

Common uses: how-to videos for colleagues or family, showing a bug to support, recording a presentation with narration, or keeping a copy of a webinar (with the host's permission).

Browser	Screen, window, tab	Tab or system audio	File format
Chrome, Edge (desktop)	Yes	Tab audio; full system audio on Windows	MP4 (H.264) in current versions
Firefox (desktop)	Yes	Usually not	WebM, convertible to MP4
Safari (Mac)	Yes	Usually not	MP4
Phone and tablet browsers	No	No	–

Mobile browsers don't allow screen capture. Use your phone's built-in recorder instead: on iPhone, add Screen Recording to Control Center; on Android, it's in the Quick Settings panel on most phones.

Tick Tab or system audio to capture what the shared tab or screen plays, such as a video or a call. In Chrome and Edge you also need to tick Share tab audio (or Share system audio) in the browser's sharing dialog. Tick My voice too to add your microphone for narration. If both are on, they are mixed into one audio track.

If the microphone can't be accessed, recording continues without it and a message tells you.

MP4 (H.264) is the default because it opens everywhere: Windows, Mac, phones, TVs, video editors, email and messaging apps. Current Chrome, Edge and Safari record MP4 directly; after recording, the page shows the exact codecs used (for example MP4 (H.264 + Opus)).

If your browser can't record MP4 (Firefox, for example), it records WebM (VP9) and offers a Convert to MP4 button afterwards. The conversion uses your browser's built-in video encoder and takes from about half a minute to a few minutes depending on length. WebM files are smaller and play in browsers and VLC, but some editors and phones don't open them.

1. Share only what's needed. A window or tab is safer than the whole screen: notifications, other windows and passwords stay out of the video.
2. Turn on Do Not Disturb so messages don't pop up mid-recording.
3. Zoom in on what you're showing so text is readable in the video.
4. Move the mouse slowly and pause briefly between steps.
5. Do a 10-second test to check the sound.

The recording is made on your device and leaves it only if you send it. Before sharing, watch it through for personal data. Ask permission before recording other people in a call, and note that streaming services usually show a black picture when captured.
