Video to MP3 Converter
Need just the audio from a video — a podcast episode, a lecture, a song, a voiceover? Our video-to-MP3 converter extracts the audio track and hands you a clean MP3, all inside your browser.
Here's the part that matters: your file never leaves your device. The conversion runs locally using FFmpeg (the open-source media toolkit), compiled to WebAssembly. No uploads, no queues, no 'your file is too large' paywalls, no waiting for a server.
It handles MP4, WebM, MOV, MKV, and AVI, and outputs a high-quality MP3 (192 kbps) that plays everywhere.
Powered by FFmpeg (open source) running in your browser — nothing is uploaded.

100% private
Conversion happens entirely on your device via WebAssembly. Your videos are never uploaded to any server — we couldn't see them if we wanted to.

MP3s are encoded at 192 kbps — transparent quality for speech and more than enough for music on the go.
No limits, no signup
Convert as many files as you like. No accounts, no watermarks, no 'premium unlock' for longer videos.
Frequently asked questions
Is my video uploaded anywhere?+
No. The converter loads the FFmpeg engine into your browser tab and processes your file locally. You can even disconnect from the internet after the page loads and it still works.
Which formats can I convert?+
MP4, WebM, MOV, MKV, and AVI — basically anything with an audio track. The output is always MP3.
Why does the converter take a moment to load first?+
Your browser downloads the FFmpeg engine (about 30 MB) once, then caches it. Conversions after that start instantly.
What quality is the MP3?+
192 kbps constant quality — excellent for voice and very good for music. If you need lossless, keep the original video file instead.
Is it really free?+
Yes. FFmpeg is open-source and the conversion costs us nothing since it runs on your device — so there's nothing to charge for.
