Convert WebM to MP4
Convert a WebM video to MP4 for easier playback, sharing, and editing.
How it works
Choose a WebM file, keep MP4 selected, and start the conversion. WebM video and audio are decoded and encoded for the MP4 container.
Result
An MP4 file with H.264 video and AAC audio that works in common players, editors, phones, and presentation software.
Limitations
The conversion re-encodes the media. Processing time and memory use increase with video duration and resolution.
