HOW IT WORKS
1
Drop the webm video
Drag the WEBM file in. Your browser reads it locally - its contents stay on your device.
2
Pick MP3
The audio track is extracted and encoded as MP3 right here.
3
Download the audio
Your MP3 saves to your device, ready for any player.
Why convert here, not there
No upload, ever
The webm never touches a server; its soundtrack becomes a mp3 inside this tab.
Local conversion
There is no file-upload step. Click Convert to extract audio after the converter engine has loaded.
No account, no daily cap
No per-day limit, no account, no watermark on your mp3.
The two formats, briefly
| WEBM | WebM is a media container. This converter writes VP8 video at a fixed 1 Mbps with Vorbis audio when present. | |
|---|---|---|
| MP3 | MP3 is a lossy audio format. This converter encodes it at the selected bitrate rather than copying the original audio stream. | |
When you need this
- Extract the soundtrack from a WEBM video for an audio-only workflow that accepts MP3. This does not keep the picture. A video with no audio track cannot produce meaningful audio.
WEBM vs MP3: what changes
| WEBM | MP3 | |
|---|---|---|
| Kind | Video | Audio |
| Compression | Depends on source encoding | Lossy audio |
| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |
| Opens on | Check the source in your app and browser. | Check the downloaded file in the receiving app. |
| Best for | Keep the original as your source. | MP3 workflows, subject to the limits below. |
Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.

Why convert WEBM to MP3?+

Which quality should I pick?+
The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
Does converting WEBM to MP3 lose quality?+
This export uses lossy audio encoding. The source WEBM may contain different codecs or recording quality; re-encoding cannot improve the original. Compare the result before deleting the source.
Is there a file size limit?+
The hard cap is 2 GB per file. The practical limit is your device: conversion runs in its memory, so very large files can fail on phones with little free RAM. There is no server-side cap because nothing is uploaded.
Does my file get uploaded anywhere?+
No. The file is read and converted by code running in this browser tab. Your file is never sent to a server - its contents stay in this tab.
