Convert MKV to MP4 for free
MKV files from screen recorders and downloads often won’t play on phones or TVs, or upload to forms. MP4 will. Convert yours here without uploading it.
How to convert MKV to MP4
- Choose your MKV file above, or drop it on the box.
- Check that MP4 is selected as the new format.
- Press Convert, then download your MP4 file. Nothing is uploaded.
Why MKV files cause trouble
MKV is popular for screen recordings, downloads and video tools, but many phones, TVs, editors and upload forms don’t accept it. MP4 is accepted almost everywhere.
Good to know
- Only the main video and sound are kept. If your MKV has several audio languages or subtitle tracks, the extra ones aren’t included.
- When the picture and sound are of a common kind, converting is quick and leaves the quality unchanged. Otherwise they are converted, which takes a little longer.
- Recordings can be large. If the MP4 is too big to share, compress it.
Common questions
Is the quality the same after converting?
Often yes. When the video already suits the new format, the picture and sound are copied as they are and nothing is lost. When the picture has to be made again, a little quality can be lost, and the result page tells you which applied.
Is my video uploaded?
No. The conversion happens on your own device, there is no account to create, and no watermark is added to the result.
