How it works

Three steps. No uploads.

1

Drop the video

MP4, MOV, MKV, WebM, AVI — anything ffmpeg decodes.

2

Pick output format

MP3 is universal. Pick stream-copy to keep original audio quality without re-encoding.

3

Download

Audio file only. No video track. Saves at the size / quality you chose.

Frequently asked

Does this work on MP4 files?

Yes — MP4 is the default. Also MOV, MKV, WebM, AVI, 3GP, FLV, and most other containers.

Do my videos get uploaded?

No. Everything runs via ffmpeg-wasm inside your browser tab. We log aggregate size / format / duration only — never filename, never contents.

Can I keep the original audio quality?

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).

File size limit?

50MB for the in-browser tool. Video is dense, so even a 2-minute 1080p clip is often around the cap. For longer files, upload to Whipscribe — we extract, transcribe, speaker-label, and let you export — all in one flow.

Want the transcript too?

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.
