Convert MKV to MP4
MKV (Matroska) holds high-quality video, but phones, browsers and social uploads often refuse it. This transcodes an MKV to an H.264 MP4 with WebCodecs in your browser — the same picture in a container that plays everywhere. Nothing is uploaded and there is no size cap.
Tutto avviene nel tuo browser: il file non viene mai caricato.

Domande frequenti
What happens to multiple audio or subtitle tracks in the MKV?
MP4 carries the video and the primary audio track. Extra audio tracks and embedded subtitles that MKV can hold are not kept — if you need a specific audio track, select it in a player first. For subtitles, convert them separately with the subtitle tools.
Is the file uploaded?
No. It is transcoded with WebCodecs on your own device — nothing is sent to a server, so there is no account, no quota and no size limit. Very large 4K files depend on your device’s memory. Chrome, Edge and Firefox work best.
