How to remove audio from a video (mute it permanently)
Strip the sound out of a clip for good — to kill background noise, avoid a copyright claim, or prepare footage for a new soundtrack.
Muting a video in a player only affects your playback — send the file to someone else and the sound is still there. Removing the audio track deletes it from the file itself, so it's silent everywhere, for everyone.
Remove the sound from a video
Open the Mute Video tool
Drop your clip in. It's processed in your browser, not uploaded anywhere.
Export
The audio track is stripped out and the video is downloaded silent. The picture is untouched.
When you'd want to
- Background noise — wind, traffic, a conversation you didn't intend to record.
- Music playing in the background that would trigger a copyright claim on YouTube, Instagram or TikTok.
- Screen recordings where the system audio isn't wanted.
- Footage that's about to get a new soundtrack anyway.
- Smaller files — the audio track is a real chunk of the size on short clips.
Save the audio before you delete it
Muting is permanent for that output file, so if there's any chance you'll want the original sound, run the clip through Extract Audio first and keep the MP3 or WAV. Your source file isn't modified either way, but having the audio saved separately means you can put it back later.
Removing the audio to replace it
If the plan is a new soundtrack, you can skip the mute step entirely — Add Music to Video in Replace mode swaps the audio out in one pass, which saves a re-encode. Use Mute only when you want silence as the end result.
Can I remove just the background noise and keep the voice?
Not with muting — it removes the entire audio track, voice included. Separating a voice from the noise behind it is a different problem that needs source separation. What often helps in practice is extracting the audio, running Normalize Audio to lift the speech, and putting it back.
