Extract Audio from Video

Pull the soundtrack out of a video as WAV, Opus, AAC, or M4A. Fast no-re-encode path is used when the source codec and target container are compatible.

What it does

Drop a video, pick a target audio format, and the tool extracts the audio track. When the source already uses the target codec (e.g. AAC video to .m4a), the export is a packet-level copy — instant and bit-identical.

When formats don't match the tool transcodes. Output bitrate defaults to a sensible 128 kbps for lossy targets and uncompressed PCM for WAV.

How to use it

Drop the video — Any common video format with an audio track.
Pick the audio format — WAV for uncompressed editing, AAC/M4A for broad compatibility, or Opus for the smallest reasonable file.
Process and download — Fast path completes in a couple of seconds even for long videos. Transcodes show a progress bar.

When to use it

Podcast cleanup

Strip the audio from a video recording to publish as an audio-only podcast.

Music from concert footage

Save just the soundtrack from phone-recorded concert video to listen on the go.

Transcription input

Most speech-to-text tools want pure audio. Extract and feed straight into Whisper / Otter / etc.

FAQ

Will the extracted file be smaller than the original?: Yes — much smaller. Video is the bulk; audio alone is typically 5–15% of the total size.
Why is my AAC extract instant when others take time?: AAC video to .m4a is a same-codec copy — packets move from one container to another without decoding. Cross-codec extractions re-encode.
