Good to know
WebM is a web video format often produced by screen recorders and web downloads. Some players and editors cannot open it.
MP3 is the most widely supported audio format. Its lossy compression removes sounds people barely hear, keeping files small, and it plays on virtually every phone, car stereo and speaker.
Converts the sound from screen recordings or downloaded WebM files to MP3, which plays on almost every player and phone.
Conversion runs inside this browser and files are never sent over the internet. Because your phone or computer does the work, long videos may take a little while.
FAQ
Does it work with audio-only WebM?
Yes. Audio-only WebM (Opus) files convert to MP3 the same way.
Are my files uploaded?
No. Every conversion runs in your browser on your own device.
Does it work with long videos?
Yes, but it uses your device’s power, so a one-hour video may take a few minutes, and files over 2 GB may fail on phones.
