About MKV to MP4
MKV to MP4 converts MKV video to MP4 so playback and upload targets stop rejecting the original container.
Upload the MKV file, convert, and download the MP4 result. The flow is aimed at everyday clips - phone recordings, screen captures, and short shares - where compatibility matters more than advanced encoding controls.
Use it when a site accepts MP4 only, when a player struggles with MKV, or when you are standardising exports before editing. Processing runs for the conversion job; keep a local original if you need an archive master.
Example workflow
Use MKV to MP4 when your player, editor or upload form requires MP4 rather than MKV. Re-encoding can change file size and quality. A lossless output cannot restore details already lost in a compressed source.
Output checks and limits
Accepted inputs: MKV. The current processing duration limit is 30 minutes. The upload size shown for your plan also applies; codec compatibility and processing time can still limit a job. Check playback, duration and sound in the downloaded file before deleting the original.
