Remove Audio from Video
Strip the audio track from a video, leaving a silent video file — same resolution and codec.
What is Mute Video?
A mute tool for producing silent video: screen recordings with a noisy keyboard, clips with copyrighted music, or footage that needs a new soundtrack.
How it works
The video stream is copied byte-for-byte and the audio stream is simply left out of the output. Nothing is re-encoded, so the operation is effectively instant and lossless.
- 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
Does it re-encode the video?
No. Streams are copied, so quality is untouched and the file just gets smaller.
Can I add new audio afterwards?
Yes — mute the clip here, then join it with your own audio using the Audio Merger or an editor. The Merger can also combine a silent video with a separate track when both are re-encoded.
Why is the file only slightly smaller?
Video dominates file size. Removing a 128 kbps audio track from a 5 Mbps video saves only a few percent.
