Extract Audio from Video
Pull the audio track out of a video file and download it as MP3 or WAV.
What is Extract Audio?
A video-to-audio extractor for ripping the soundtrack from a recording, saving a lecture's audio, or grabbing a song from a performance video.
How it works
The video stream is discarded entirely and only the audio is decoded and re-encoded to the format you choose. The optional switch applies EBU R128 loudness normalisation during extraction.
- Load your file. Drag a file onto the drop zone or pick one from your device. It is read locally by the browser and never uploaded.
- Set the options. Adjust the handles, format, quality or threshold controls — the preview updates as you change them.
- Process and download. Run the tool, then download the result. Compare the reported before/after size for compressors and converters.
Examples
A 42 MB podcast episode → 9 MB MP3
Trim the intro, normalise to −16 LUFS, and export at 96 kbps mono — a typical interview lands around a fifth of the original size.
A phone video with the wrong orientation
Rotate 90° and the width/height swap in the output, so it plays upright in every player instead of relying on metadata flags.
Common mistakes
Expecting instant encoders
Video encoding runs in single-threaded WebAssembly, so a clip takes roughly its own length (or a little longer) to re-encode. Stream-copy operations are near-instant by comparison.
Re-encoding when a copy would do
Trimming, removing audio and joining same-codec clips can copy streams without re-encoding — pick the copy option when it is offered to avoid any quality loss.
Ignoring the first-load download
The media engine is about 31 MB and is fetched on first use, then cached. The first conversion on a connection is slower than every later one.
Frequently asked questions
Is this faster than converting the whole video?
Yes. Only the audio stream is touched, so a long video extracts quickly even though the engine is single-threaded.
What if the video has no audio?
You will get a clear error from the engine — there is nothing to extract from a silent clip.
Which format keeps the best quality?
WAV or FLAC are lossless and ideal for further editing. MP3 at 192–320 kbps is fine for listening and sharing.
