How to convert WebM to MP4
- Choose your WebM video.
- The output is set to MP4; choose the quality used if the video has to be re-encoded.
- Press Convert and download the MP4 file.
Good to know
- WebM usually contains VP8, VP9 or AV1 video, which is re-encoded to H.264 for the widest support.
- When the video and sound can be copied into the new format as they are, they are not re-encoded: no quality loss, and very fast.
- Best in current Chrome and Edge; recent Safari and Firefox work too.

Is there a size limit?
No server-imposed file size limits. The practical limit is your device's memory: several gigabytes work on most computers.
Are my videos uploaded?
No. They are converted in your browser and never sent anywhere.
