Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Extract the audio track from WebM videos as MP3 — decoded and encoded entirely in your browser, with no upload and no length gate. Screen recordings, browser captures and downloaded clips: drop them in, the soundtrack comes out as its own file.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
From screen recording to shareable audio
WebM is what browser-based recorders and most capture tools produce, and the audio inside is often the part that matters — a call, a talk, a walkthrough narration. Extraction discards the picture and re-encodes the sound to MP3, the format that plays absolutely anywhere. MP4 to MP3 covers the MP4/MOV twin, and for editing-grade PCM instead, MP4 to WAV extracts losslessly.
Frequently asked questions
Which WebM files work?
Anything your browser can play — VP8 or VP9 video with Opus or Vorbis audio. The video track is discarded; the audio is decoded and re-encoded to MP3 at the bitrate you pick.
Is quality lost in the conversion?
One lossy encode to MP3 happens — inaudible for speech at 128 kbps and safe for music at 192 kbps and up. Pick a higher bitrate when the source matters.
Can I get lossless audio instead?
Yes — on the audio tab choose WAV or FLAC as the output; MP3 is simply the small, plays-anywhere option this page arrives set to.
Is it private?
Yes. The audio is decoded and re-encoded entirely in your browser — recordings never leave your device, and the server does nothing but deliver this page. Voice memos, interviews, demos: none of it is uploaded anywhere. Want proof? Run one file through, switch your connection off, and run another — it still works.
