How to convert MP4 to WebM
- Choose your MP4 video.
- The output is set to WebM; choose the quality used if the video has to be re-encoded.
- Press Convert and download the WebM file.
Good to know
- The video is re-encoded to VP9 (or VP8) and the sound to Opus.
- 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.

Perguntas frequentes
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.
