Conversion starts instantly — the audio is extracted and encoded to MP3 right in your browser, with live progress.
Download your MP3 file.
Everything happens right here in your browser: your file is converted locally on your device with WebAssembly FFmpeg and is never uploaded to any server. Because there is no upload, there is no practical length limit either — multi-hour recordings and files up to 8GB convert just fine, and even a huge file starts instantly.

About video to MP3 conversion
Pull the sound out of any video — MP4, MOV, MKV, AVI, WebM, WMV and more — and save it as an MP3 that plays everywhere. Lectures, concerts, interviews, voice-over reference tracks: if it has an audio track, this extracts it.
Most video-to-audio sites make you upload the whole video first, wait in a queue, then download — slow and a privacy risk for anything personal. This one skips all of that: the extraction runs in your own browser with WebAssembly FFmpeg, so nothing is ever uploaded. Videos other sites reject for size — phone recordings, screen captures, multi-hour meetings — start processing instantly here.
Frequently asked questions
Drop the video into the box above and click Start. The audio track is separated from the video and encoded to MP3 in your browser; the video stream is simply discarded. Download the MP3 when the progress bar completes.
Most converters need the whole file on their server before they can touch it — that's a slow upload, a queue, and your video sitting on someone else's storage. Here the extraction runs with WebAssembly FFmpeg directly in your browser, so the video never leaves your device. That's also why there's no realistic size ceiling: an 8GB file starts converting the instant you drop it in, no upload wait at all.
MP4, M4V, MOV, MKV, AVI, WebM, WMV, TS, MPG, FLV and 3GP, with all the common audio codecs inside them (AAC, MP3, AC-3, DTS, Vorbis, Opus, PCM, WMA). If the file plays, the audio almost certainly extracts.
No — the video stream is never touched or re-encoded, which is why extraction is so much faster than any video conversion. Only the audio is decoded and written out as MP3.
No. The conversion runs entirely in your browser using WebAssembly (FFmpeg). Your recording never leaves your device — that is also why there is no upload wait, no queue and no file-size pricing. For personal recordings, lectures and meetings this matters more than anywhere else.
Up to 8GB on desktop browsers and 2GB on mobile — big enough to pull the audio out of a multi-hour lecture or meeting recording. There is no limit on the number of files, no signup and no watermark.
192–320kbps, which is transparent for speech and very close to transparent for music. The audio stream is decoded once and encoded once — there is no extra generation loss from server-side re-processing.
Yes — completely free and unlimited, with no watermark, signup or daily quota. Because the conversion runs on your own device instead of our servers, there are no processing costs to charge for.
Yes. It runs in any modern browser — Chrome, Safari, Edge or Firefox — on Windows, macOS, ChromeOS, Linux, iOS and Android. There is nothing to install.
Audio-only work is fast: there is no video to re-encode, so even the soundtrack of a long video converts in well under real time. Files whose audio is already MP3 are rewrapped without re-encoding and finish in seconds.
Yes. Our sister site Red Panda Transcribe (redpandatranscribe.com) turns the MP3, M4A or WAV you export here into text right in your browser — like this tool, nothing is uploaded, and there is no time limit and no signup. It exports TXT, SRT and VTT.
