How do I convert MKV to M4V?

Drop your MKV file onto the converter above, make sure M4V is selected, and click Convert. When it's done, download the M4V file — it usually takes a few seconds.

Is it safe to convert MKV to M4V here?

Yes. MKV to M4V conversion happens entirely inside your browser using WebAssembly, so your file is never uploaded to any server.

Is the MKV to M4V converter free?

Yes — free with no watermark. Signed-out visitors can convert 25 files a day, and a free account raises that to 250.

Will converting MKV to M4V reduce quality?

M4V is a lossy format, but our defaults are tuned to be visually indistinguishable for most files. You can raise the quality under Options.

Can I convert multiple MKV files at once?

Yes. Add up to 5 files at a time without an account, 10 with a free account and up to 500 on paid plans, then download them individually or as a single ZIP.

Can I convert M4V back to MKV?

Yes — use our M4V to MKV converter. Note that converting back and forth between formats can't recover detail lost to lossy compression.
