Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many MKV files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Which formats can I convert MKV to?
GIF, MP3, WAV, M4A, AAC, FLAC, OGG, Opus, WebM, MP4 and MOV.
