Free Online Screen Recorder

About the Screen Recorder

This screen recorder captures a screen, an application window, or a browser tab directly from your device. It is handy for recording a presentation, demonstrating a bug, narrating a tutorial, or saving a video call when everyone has given permission. You can include your microphone and, on supported browsers, the audio from the shared tab. Recordings are produced locally and are never uploaded.

How to record your screen

1. Optionally tick “Include microphone” and choose a video bitrate.
2. Click the screen icon. The browser asks what to share; pick a screen, window, or tab.
3. If you want system or tab sound, enable the audio option in that sharing dialog. Chrome and Edge support tab audio; Firefox and Safari generally do not.
4. Use Pause and Resume while recording, then click Stop when finished.
5. Preview the result and download it.

Audio mixing

When both system audio and microphone audio are available, the tool mixes them with the Web Audio API so the final file contains a single balanced audio track. If only one source is available, that source is recorded directly. Keep in mind that browsers only capture tab audio when you explicitly enable it in the sharing picker, and some sites block audio capture entirely.

Output format

The recorder asks the browser whether it supports video/mp4;codecs=avc1.42E01E. If it does, the file is saved as MP4 with H.264 video. If not, the browser records WebM and the download link and file extension say so. Recording a full screen with continuous motion can produce large files; the Small bitrate preset keeps size down at the cost of sharpness. Recordings are limited by available memory and by the browser's maximum recording length. Keep the recording tab visible and avoid sleeping the device.
