How to convert WebM to MP4
WebM videos from the web and screen recorders often won't play on iPhones, in video editors or on TVs. MP4 works everywhere.
- Drop your WebM file into the box above, or add it from a link.
- MP4 is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your MP4 file.
To do this from your own code, call the FileForge API with "output_format": "mp4".
Good to know
- Video is converted to H.264 and audio to AAC.
- Screen recordings with mostly still content convert quickly and stay small.
- Trim the start and end in the settings if you only need part of the clip.
About the formats
.webm
WebM is an open video format designed for the web, usually with VP9 or AV1 video. Browsers play it well, but iPhones, video editors and many TVs don't.
.mp4
MP4 is the most widely supported video format. It plays on practically every phone, browser, TV and editor, usually with H.264 video and AAC audio inside.
Questions
Why do screen recorders save WebM?
Browsers can record WebM natively, so many web-based recorders use it. Converting to MP4 makes the recording easy to share and edit.
