Why remove the sound from a video?
There are plenty of good reasons to strip the audio from a clip:
- Background noise such as wind, traffic, a TV or a crowd, when you'll add music or a voice-over later.
- Private conversations caught in the background of a family or work video before you share it.
- Copyrighted music playing in a shop, car or venue, which can get videos muted, blocked or demonetised by social platforms.
- Silent loops for websites, presentations and digital signage, where autoplay usually requires the video to be muted.
- Smaller files: removing the audio track saves its share of the file, typically 1–2 MB per minute.
Is the sound removed or just turned down?
Removed completely. Some apps 'mute' a video by setting the volume to zero, leaving the audio data in the file, where anyone can recover it. This tool deletes the audio track instead. The output contains only the video stream, so there's nothing left to turn back up.
Does muting a video lose quality?
Removing a track doesn't require touching the pictures. The video stream is copied exactly as it was, frame for frame, into a new file without the audio. There's no decoding and no re-encoding, so there's no quality loss, and it takes seconds even for long videos and on phones.
The file keeps its format: an MP4 stays MP4, a MOV stays MOV, a WEBM stays WEBM. Only the main video track is kept, so subtitle and data tracks are dropped too.
Keep the sound separately
If you might want the audio later, for a transcript, a podcast clip or a voice-over reference, save it first with the MP4 to MP3 converter on the same original file. Then you have a silent video and a separate MP3, and you can edit them independently.
Social platforms and muted uploads
Instagram, TikTok and Facebook let you add licensed music in their own editors. Uploading a muted video and adding a track from the app's library is the safest way to avoid copyright claims from background music. Muted videos also autoplay more reliably on websites, because browsers block autoplay with sound by default.
The tool runs in your browser and the file never leaves your device, so private recordings stay private while you clean them up.
How do I mute a video on iPhone or Android?
On iPhone, open the video in Photos, tap Edit and tap the speaker icon at the top left so it shows as muted, then tap Done. Videos you share from Photos afterwards have no sound. Google Photos on Android offers a mute button in its video editor on most phones. Both are quick for clips you'll send straight from the phone.
This tool is the better fit on a computer, for videos that aren't in your camera roll, or when you need a guaranteed silent file to upload somewhere, because the audio track is removed rather than just switched off in an editor.
Can I mute only part of a video?
This tool removes all of the audio. To silence just a few seconds, such as a name, a swear word or a phone ringing, you need an editor that can cut or duck the audio in one section; the free editors that come with Windows (Clipchamp) and Mac (iMovie) both can. Alternatively, cut the video into parts with the Video Cutter, mute the part you need, and join the parts in an editor.
