Frequently asked questions
Why convert to MP4?
MP4 with H.264 and AAC plays on every phone, computer, TV, browser and social network.
Will it lose quality?
Not when the video is already H.264 or HEVC — it is copied into MP4 without re-encoding. Other codecs are encoded at very high quality.
Can I convert several videos?
Yes — add as many as you like; each gets its own download, plus a ZIP.
Which formats are supported?
Open MP4, MOV, MKV, WebM, M4V, 3GP, TS and — after a quick in-browser conversion — AVI, WMV, FLV and MPEG. Save as MP4, MOV, WebM, MKV, TS, AVI, FLV, 3GP, WMV or OGV with H.264, HEVC, VP9 or AV1.
Can I do other edits too?
Yes — every video tool here has the full editor: trim and cut, crop, rotate, resize for social media, speed, reverse, loop, filters, fades, text, logo, volume and export settings, with undo.
Is my video uploaded?
No. The video is converted in your browser, using your device's built-in video encoder (WebCodecs) where available, so the video never leaves your device and there's no upload wait.
