Remove audio from video

The saving is the size of the sound track, which depends on its bitrate, not on the picture. A sound track takes its bitrate in kilobits every second, so the table below is simple arithmetic: kilobits a second, times the seconds, divided by eight. For most screen and meeting recordings the sound is a few percent of the file, because the picture is much bigger; for a talking-head video with a mostly still picture it can be a fifth or more.

The page shows the real size before and after for your own file once it is done.

Remove all sound when the sound adds nothing or must not be shared: a screen recording that picked up a call, background music you have no rights to, a product demo you will narrate again, or a clip for a page where it plays on a loop. It is also the quickest way to send a smaller file.

Mute part of it when the rest of the sound matters: a meeting recording where someone said something private, a lesson with a phone ringing in the middle, or a few seconds of copyrighted music in an otherwise fine video. If the part is long or there are several, mute one, then open the result and mute the next.

If you might want the sound later, keep the original, or save the sound on its own first with the extract audio from video tool. To cut the part out of the video altogether, picture and all, use the video trimmer; to take out quiet gaps, use remove silence from video.

Your computer or phone can probably do this already. These are free:

QuickTime Player (Mac)

1. Open the video in QuickTime Player.
2. Choose Edit, then Remove Audio.
3. Choose File, then Save, and give it a name.

Free and already on every Mac. It removes all the sound; it cannot mute just a part.

Photos (iPhone and iPad)

1. Open the video in Photos and tap Edit.
2. Tap the speaker button so it is crossed out.
3. Tap Done.

The quickest way for a video already on your phone. It mutes the whole video.

Google Photos (Android)

1. Open the video in Google Photos and tap Edit.
2. Tap Mute (on a Pixel, tap Audio, then Mute).
3. Tap Save. Google Photos saves the muted video as a copy.

Clipchamp (Windows)

1. Open Clipchamp, which comes with Windows 11, and add the video to the timeline.
2. Select the clip and click the speaker symbol. To mute a part, split the clip at both ends first and mute the middle piece.
3. Export the video.

Re-encodes the whole video on export, which takes about as long as the video plays and can lower its quality.

FFmpeg (Any computer)

1. To remove all the sound without re-encoding: ffmpeg -i in.mp4 -c copy -an out.mp4.
2. To mute 0:30 to 1:15 only: ffmpeg -i in.mp4 -c:v copy -af "volume=0:enable='between(t,30,75)'" out.mp4.

Free and exact, from the command line. This page does the same two jobs without installing anything.

This page needs nothing installed, works the same on any computer and phone, never re-encodes the picture, and can mute a part without an editor.

• The result is the same kind of file as the original: an MP4 stays an MP4, a WebM stays a WebM. To change the format too, use the WebM to MP4 converter first.
• Only the first video track is kept. Subtitles, chapters and any second video track are left out. Every sound track goes when you remove all sound; muting a part keeps only the first sound track, as stereo at most.
• Muting a part re-encodes the sound, which needs WebCodecs (current Chrome, Edge, Safari and Firefox). Removing all the sound needs no codecs, so it works even on a video this browser cannot play.
• One part is muted at a time. For several, run it again on the result.
• In Chrome and Edge on a computer, a big result is written straight to a file you choose, so there is no size limit. In other browsers files go up to 2.0 GB and the result has to fit in memory.
• It works on a phone, but a long video is easier on a computer, where the file is to hand.

• FFmpeg calls taking packets across without decoding or encoding them stream copy, and its -an option leaves the sound out. ffmpeg -i in.mp4 -c copy -an out.mp4 is the same job as this page’s “Remove all sound”. Source, checked 9 November 2026.
• QuickTime Player on a Mac has Edit > Remove Audio, which leaves the movie video only. Source, checked 9 November 2026.
• In Clipchamp, the editor that comes with Windows 11, clicking the speaker symbol on a clip mutes it, and Detach audio in the Audio tab splits the sound off so it can be deleted. Source, checked 9 November 2026.
• On iPhone, tapping the speaker button while editing a video in Photos takes the sound out of the saved video, and it can be put back later with Revert. Source, checked 9 November 2026.
• Google Photos on Android can mute a video while editing it: Mute on most phones, under Audio on Pixel phones. Source, checked 9 November 2026.
• FFmpeg’s volume filter can be switched on for part of a video only, so -af "volume=0:enable='between(t,30,75)'" silences 0:30 to 1:15 and leaves the rest. Source, checked 9 November 2026.
