Where WebM files come from
WebM is the format browsers use when they record. Screen recorders, online voice recorders, video calls recorded in the browser and many downloaded videos end up as WebM files, which iPhones, Windows Media Player and many editing programs struggle to open.
If you only need what was said or played, converting the WebM to MP3 gives you a small audio file that works everywhere: send a meeting to a colleague, transcribe an interview or keep the soundtrack of a clip.
Frequently asked questions
How do I convert WebM to MP3?
Select the WebM file on this page, choose the quality and click Convert to MP3. The audio track is extracted and saved as an MP3 in a few seconds, without installing any program.
Can I convert an audio-only WebM recording?
Yes. Online voice recorders often save WebM files that contain only sound. They convert the same way as WebM videos and become regular MP3 files.
Why does my WebM file not play on iPhone?
Apple devices have limited support for WebM, especially for its audio formats. Converting to MP3 gives you a file that plays on iPhone, iPad and every other device.
Which quality should I choose?
For meetings, lessons and voice recordings, 128 kbps is plenty and keeps files small. For music or a soundtrack you want to keep, choose 192 or 320 kbps.
Are my recordings uploaded to a server?
No. The audio is extracted inside your browser on your own device, so recorded meetings and calls are never sent to us or stored anywhere.
