How to remove audio from a video
Removing audio means writing a new file that contains only the video stream. Because the picture doesn't need to change, a good tool copies it without re-encoding, so muting is instant and lossless, and the file gets slightly smaller. Phone editors often just turn the volume to zero, which keeps a silent track and may re-encode.
Use mute video to drop the audio track losslessly in your browser. Want the sound instead of the picture? Extract audio saves it as MP3.
How to mute a video with Videozify
- Open Mute video.
- Drop in the video (MP4, MOV, MKV, WebM and others).
- Press Remove audio. The video stream is copied unchanged, so it finishes in seconds.
- Preview to confirm it's silent, then download.
Why remove audio?
- Background noise, wind or private conversations you don't want to share
- Copyrighted music playing in the background, which can get videos blocked on social platforms
- Website background videos, which browsers only autoplay when muted
- Adding a new soundtrack or voice-over later
- Saving a little space on tight file-size limits
Lossless muting vs volume to zero
A proper mute removes the audio stream completely and copies the video stream bit for bit. There's no quality change, no re-encoding time and a slightly smaller file. Setting the volume to zero in an editor keeps a silent audio track and usually re-encodes the whole video on export, which takes longer and can slightly reduce quality.
For website background videos, a file with no audio track at all is best. Some browsers check for the presence of audio when deciding whether autoplay is allowed.
Mute on iPhone
Open the video in Photos, tap Edit, then tap the speaker icon at the top left so it shows as muted, and tap Done. iOS keeps the audio hidden but restorable. When you share, the exported file is silent.
Mute on Android
Google Photos: open the video, tap Edit, tap the speaker icon to mute, and Save copy. Samsung Gallery offers a similar volume or mute control in its video editor.
Mute on Windows and Mac
Windows: in Clipchamp, select the clip on the timeline, set the volume to 0% or detach and delete the audio, then export. That's a re-encode.
Mac: QuickTime Player has Edit > Remove Audio, then File > Save or Export As. It's quick and doesn't re-encode the video when saving as .mov. iMovie can detach audio and delete it.
Replacing the soundtrack
To put music or a voice-over on a video, mute it first, then add the new audio in an editor such as Clipchamp, iMovie or CapCut. Make sure you have the rights to any music you use; royalty-free libraries and the music catalogues built into social apps are safe options.
Muting for website backgrounds
Hero and background videos on websites should be short (5–20 seconds), muted, looped, and small, usually under 3–5 MB. Remove the audio, trim to a loopable section, compress to 720p or 1080p at a modest quality, and use attributes such as autoplay, muted, loop and playsinline on the video element. Provide a poster image so something shows before the video loads, and respect visitors who prefer reduced motion.
Muting for privacy
Phone videos often capture conversations in the background. Before sharing a clip of a child's performance, a pet or a place, listen to it with headphones. If anything private is audible, mute the clip or replace the audio with music. Removing the audio track also removes any chance of someone enhancing quiet background speech later.
Partial muting
Sometimes you only need to silence a few seconds, such as a name being spoken or a bad word. One approach: split the video at the start and end of the section, mute that part, and merge the three parts back together. The merge re-encodes the video, so do this as a final step. A full editor can instead lower the volume with keyframes for just that moment.
Checking that the audio is really gone
Open the muted file in VLC and choose Audio > Audio Track. If the only option is Disable, there's no audio stream. On a Mac, Command-I in Finder shows the codecs; a muted file lists only the video codec. That matters for autoplay and for platforms that detect copyrighted music in silent tracks.
Replacing audio vs removing it
Some platforms detect copyrighted music in uploaded videos and mute or block them. Removing the original audio before upload avoids those claims, and adding licensed music from the platform's own library afterwards keeps the video lively. For voice-overs, record your narration separately with a good microphone and combine it with the muted video in an editor such as Clipchamp, iMovie or CapCut. Clean narration usually sounds far better than the camera's built-in microphone, especially outdoors.
Muting on a Chromebook or Linux
ChromeOS has no built-in mute option for video files, but Videozify runs in Chrome. On Linux, Shotcut and Kdenlive can detach and delete audio, and ffmpeg removes it losslessly from the command line with the -an option. Videozify works in any modern browser, so no installation is needed on any platform, including school and work computers where installing apps isn't allowed.
Which formats keep a silent file small
MP4, MOV, MKV and WebM can all contain video without audio. Muting keeps the original container and video codec, so an MP4 stays an MP4 and plays in the same places. If you also want a smaller file, compress after muting; the compressor won't need to process any audio.
Keeping the audio separately
If you might want the sound later, extract it to MP3 before muting. The extract audio tool saves just the soundtrack, which is handy for podcasts, voice notes and music you recorded yourself.
Frequently asked questions
Does muting a video reduce quality?
- No. The picture is copied unchanged.
Will the file get smaller?
- Slightly, by the size of the audio track.
Can I remove only part of the audio?
- Split the video, mute the part, then merge, or use an editor's volume keyframes.
Is my video uploaded?
- No. Muting runs in your browser.
Can I get the audio back?
- Not from the muted file. Keep the original, or extract the audio first.
Why won't my background video autoplay?
- Browsers require muted video for autoplay. A file with no audio track is safest.
Can I remove audio from a GIF?
- GIFs never contain audio, so there's nothing to remove. Mute applies to video files like MP4 and MOV.
Does muting work on long videos?
- Yes. Copying the video stream is fast, even for long files.
Will social apps add sound back?
- No, but they let you add music from their libraries.
Can I mute a video on a Chromebook?
- Yes. Videozify works in Chrome on ChromeOS.
Can I mute a video on Windows without installing anything?
- Yes, with Videozify in Edge or Chrome.
Will muting remove copyrighted music claims?
- Removing the track removes the music, so automated detection has nothing to match.
Can I mute a video on iPhone without the Photos app?
- Yes. Open Videozify in Safari and use the mute video tool.
