Video to MP3, the private way
Need a song from a screen recording, the audio of a lecture video, or a podcast that was only published as video? Drop the file and this tool pulls the audio track out with FFmpeg compiled to WebAssembly — running entirely in your browser tab. A thumbnail and duration appear as soon as the video loads, so you know you grabbed the right file before converting.
Why no-upload matters for video
Video files are big. Upload-based converters make you push hundreds of megabytes to their server before work even starts — and most cap uploads at 100 MB anyway. Here the file never moves, so a 1 GB recording starts converting immediately.
Output formats
- MP3 — best for music and sharing; choose your bitrate.
- WAV — lossless; ideal if you'll edit the audio next.
- M4A — AAC, native on Apple devices, smaller than MP3 at equal quality.
FAQ
Which video formats can I extract audio from?
MP4, WebM, MOV, MKV and most other containers. FFmpeg in your browser handles virtually any format.
Does the video get uploaded?
No. The file is read into your browser's memory and processed locally — even multi-hundred-MB videos work because there's no upload to time out.
Will the audio quality drop?
Choose WAV for a lossless copy. MP3 and M4A re-encode at your selected bitrate — 192 kbps is transparent for most content.
