Drop a video, pick a target audio format, download. Runs entirely in your browser — your video never leaves your device.
Three steps. No uploads.
MP4, MOV, MKV, WebM, AVI — anything ffmpeg decodes.
MP3 is universal. Pick stream-copy to keep original audio quality without re-encoding.
Audio file only. No video track. Saves at the size / quality you chose.
Yes — MP4 is the default. Also MOV, MKV, WebM, AVI, 3GP, FLV, and most other containers.
No. Everything runs via ffmpeg-wasm inside your browser tab. We log aggregate size / format / duration only — never filename, never contents.
Yes — pick Original (stream-copy) under output format. We copy the audio track without re-encoding. Container switches to match the codec (AAC → .m4a, Opus → .ogg, MP3 → .mp3).
50MB for the in-browser tool — ffmpeg-wasm runs inside the tab and can't safely handle multi-GB videos. If you drop a file bigger than 50MB, we show a one-click switch to Whipscribe's server pipeline, which handles up to 5GB and returns both the extracted audio and a speaker-labeled transcript.
If you're extracting audio to read it: skip the extra step. Upload the video directly to Whipscribe and get a speaker-labeled transcript with timestamps. First 30 minutes free.
