Frequently asked questions
Is this video converter really free and unlimited?
Yes. No signup, no watermark, no daily caps, no locked features. It uses the open-source FFmpeg engine running entirely in your browser, so there is no server cost to throttle you on — unlike CloudConvert (25 free conversions/day) or Zamzar (2 files/day).
Are my videos uploaded to a server?
No. Conversion happens locally on your device inside your browser tab. Your videos never leave your computer — they can't be stored, viewed, or leaked by us. This also means it works on private or sensitive footage.
Which formats are supported?
Input: MP4, MOV, WebM, MKV, AVI.
Output: MP4 (H.264), WebM (VP9), MP3 or WAV audio. Files are capped at 500 MB because the whole video is held in memory during conversion.
Why is the first conversion slow to start?
The first run downloads the FFmpeg engine (about 25 MB). It's cached by your browser afterwards, so later conversions start instantly. Actual conversion speed depends on your device — a desktop converts several times faster than a phone.
What do the quality presets mean?
High keeps near-original quality at a larger size; Medium is the balanced default; Small squeezes the file down with some visible quality loss. For audio, they map to 256 / 192 / 128 kbps MP3.
Which browsers are supported?
Any modern desktop or mobile browser with WebAssembly: Chrome, Edge, Firefox, Safari 16.4+. Very old browsers may not load the converter engine.
