Questions
- My WebM file has video — does that work?
- Yes. The tool takes only the sound and leaves the picture out, so the MP3 is much smaller than the video.
- What sound does a WebM file contain?
- Opus or Vorbis. The tool reads both and converts them to MP3.
- I recorded audio in the browser and got a .webm file — what is it?
- Chrome and Edge save microphone recordings as WebM with Opus sound. It is an ordinary audio file; convert it here if a program wants MP3.
- Are my files uploaded anywhere?
- Your file never leaves your device. It is converted right here, in your browser — nothing is uploaded.
