About this WEBM to MP3 converter
WebM is Google’s open video format for the web. Browser screen recordings, Chrome extensions and many online recorders save audio as Opus or Vorbis inside a .webm file. If you only need the sound — a lecture, a song, an interview or a screen recording — this tool pulls the audio track out of your WEBM file and saves it as MP3. The conversion happens on your own device, so the video is never uploaded.
Why convert WEBM to MP3?
- Save the soundtrack of a WEBM video as a MP3 file you can play or edit anywhere.
- Make a podcast, voice note or music track out of a recording.
- Shrink a large WEBM clip down to just the audio before sharing.
Things to know
- Only the audio track is kept. The picture is dropped, which is why the MP3 file is far smaller than the original WEBM.
- If your WEBM file has no audio track, there is nothing to extract and the tool will tell you.

Frequently asked questions
How do I convert WEBM to MP3 for free?
Open this page, select your WEBM file, click convert and download the MP3. No account, no app and no payment are needed.
Are my files uploaded to a server?
No. The conversion runs inside your browser using WebAssembly, so your WEBM file never leaves your device. That also means there is no server-side size limit — only your device’s memory.
Will I lose quality converting WEBM to MP3?
The audio is re-encoded to MP3. If the page offers a quality setting, “High” keeps the difference very hard to hear; WAV output is uncompressed. The video picture is not included.
What is the difference between WEBM and MP3?
WEBM (WebM) is best for web video and browser recordings. MP3 (MPEG-1 Audio Layer III) is best for music libraries, podcasts, voice memos and anything you want to play everywhere.
Is there a file size limit?
There is no upload limit because nothing is uploaded. Very large files (several hundred MB) can be slow or run out of memory on phones, so use a desktop browser for those.
