FAQ
Will converting reduce the quality?
Converting between MP4 and MOV usually copies the video stream directly without re-encoding, so there is no quality loss. WebM (VP9) requires re-encoding; quality stays visually the same and the file is usually smaller.
Is my video uploaded to a server?
No. Everything runs locally in your browser. No uploads, no retention. Your privacy is fully protected.
Why does it say my browser is not supported?
This tool uses native WebCodecs. It works in recent versions of Chrome, Edge and Safari. Firefox is not supported yet - please switch to one of those browsers.
Which input formats are supported?
Most common video formats work as input, including MP4, WebM, MOV, MKV, AVI, M4V and OGV. Output is MP4, WebM or MOV. Keep files under 200 MB - shorter clips convert faster.
