## 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.

## Frequently asked questions

### Will the MP4 play on an iPhone?

The H.264 and AAC output is designed for broad compatibility, including current iPhone and iPad software.

### Does the converted MP4 keep audio?

Yes, when the WebM source contains a readable audio track.
