What is WebM to MP4?
WebM to MP4 converts WebM video files (VP8/VP9/AV1 codec) to the universally compatible MP4 format (H.264/H.265) for playback on any device.
When to use this tool
- Converting WebM recordings for sharing on platforms that require MP4
- Ensuring video playback on iOS and older devices

- Reducing compatibility issues in video workflows
How it works
Uses FFmpeg (via WebAssembly) to transcode the WebM video stream from VP8/VP9/AV1 to H.264 or H.265, and re-packages into the MP4 container. Audio is transcoded to AAC if needed.
