Questions about Compress Video
Why must I wait through the whole clip?
Recording happens live from playback. A two-minute video needs two minutes.
Is audio kept?
Yes, when your browser supports recording the audio track; if the clip has an unusual codec the audio may be dropped, and the tool warns you.
About Compress Video
Shrink video files by re-encoding to WebM with our free online Compress Video. 100% browser-based, fast, and private—no login or file uploads required.
These video tools cover quick clip jobs in the browser: compress a recording to a smaller file, or capture your screen and webcam with audio, then download the result straight away.
This tool runs in your browser. The file is not uploaded. Screen and webcam recording needs your permission and a modern browser; close other tabs while recording so the encoder gets enough CPU and the frame rate stays smooth.
