How to

How to remove audio from a video

A phone recording, a screen capture or an export from an editor, in any of the usual video formats.

  1. 1

    Upload the video

    Drop the file on the upload box, or click Browse video and pick it from your device. Its name and size appear in a panel underneath, with a Pick a different file button in case you grabbed the wrong one.

  2. 2

    Click Remove audio

    The clip uploads first, with a percentage bar, and then our server drops the sound track. The picture is copied as it is rather than rebuilt, so there's no long wait; each of our three test files was ready 3 to 4 seconds after its upload finished.

  3. 3

    Download the silent file

    When Silent video ready appears, click Download. The file keeps the format it came in with and gets _no_audio added to its name, so sunset.mp4 comes back as sunset_no_audio.mp4. The link expires after 30 minutes, so save the file straight away.

The three steps: drop the video on the upload box, click Remove audio in the file panel, then download sunset_no_audio.mp4 with the sound track gone

Guide

Removing audio from an MP4 or MOV without re-encoding: what changes and what stays

This tool does one thing to your file: it drops every sound track and writes the picture back out unchanged. Nothing is rebuilt, so the video you get back is the one you uploaded, bit for bit, in the same format, at the same resolution and the same number of frames per second. The whole job takes seconds whatever the length of the clip, because copying is far quicker than processing the video again.

The same sunset clip before and after: the input MP4 holds a picture track and a sound track, the output holds only the picture and is 245 KB smaller

We checked that on 21 October 2026 with three clips, and the details are at the bottom of this page. In every case the picture in the output matched the input exactly, and the file shrank by about the size of its sound track, 2 to 3 percent for these clips. The sections below cover the cases people ask about, from iPhone MOV files to clips that never had a sound track.

Quality and file size: the picture is untouched

Because the picture is copied rather than rebuilt, there is no quality loss at all, not even the small kind a careful re-save brings. The file gets smaller by about the size of the sound track and nothing else. The sound in a phone video takes about 1 to 1.5 MB a minute, so the 8 second clip in our test lost 245 KB, and a 10 minute phone video would lose roughly 10 to 15 MB. If you need the file much smaller than that, Compress Video is the tool, and it does rebuild the video.

MOV files from an iPhone

A MOV uploads and comes back as a MOV, still in the format newer iPhones record in. In our test an upright 1080 by 1920 iPhone-style MOV came back 131 KB lighter with its picture unchanged. If you also want it as an MP4, strip the audio here and then run the silent file through MOV to MP4.

Clips that have no sound track

Screen recordings, time-lapses and stock footage often have no audio track at all. The tool accepts them anyway and returns the file as it was, same size, with _no_audio added to the name. Nothing fails, but there is also nothing to remove, so if a player shows no sound for a clip you have never touched, the track was never there.

Preparing clips for Merge Video

Merge Video can't join a batch where some clips have sound and others don't; the server returns an error for that mix. The fix is to strip the audio from the clips that have it here, then merge them as an all-silent batch. We tested that path: the silent MP4 from this tool merged with a clip that never had sound in 25 seconds, and the result had no audio track. The merged video will be silent throughout, so if you want music or a voiceover, add it in an editor afterwards.

Every audio track goes, and so do subtitles

The tool keeps the picture and drops everything else, so a file with two language tracks comes back with neither, and subtitles stored inside an MKV or MP4 go with them. The tool can't mute only one section of a clip or only one of several tracks, and cutting the section out with Cut Video to silence it on its own doesn't get around that, because Merge Video can't join a silent piece back onto pieces that still have sound. For that kind of edit, use a desktop editor.

Keeping the sound as a separate file

Removing the audio here throws it away. If you need the sound on its own, for a voiceover edit or a podcast, run the original through Extract Audio first, which gives you an MP3, M4A or WAV, and then strip it from the video. Both tools read the same upload formats, so the order is simply original in, audio file out, then silent video out.

Size limit, time, and what can fail

One file at a time, up to 500 MB. Uploading is the slow part: our 22 MB clip took 1.5 seconds on a fast line, and a 500 MB file over home broadband can take several minutes, while the server allows 2 minutes for removing the sound, far more than copying ever needs. The one failure we could produce was a file with no picture, an MP3 renamed to .mp4, which stops with an error from the server. A file with an unsupported extension or over the limit is refused before anything uploads, and Cancel stops the upload, or stops the page waiting for the result; a job the server has already started runs to the end.

Last updated: 21 October 2026 · ChangeMyFile

Tested: 21 October 2026, three runs on the live tool with short cuts of Pixabay stock clips, plus one merge. An 8 second 1920 x 1080 H.264 MP4 at 29.97 fps with a 189 kbps AAC track, 7.1 MB: silent file ready 3.4 seconds after the upload, 6.8 MB, video stream checksum unchanged. An 8 second 1080 x 1920 HEVC MOV at 30 fps with a 128 kbps AAC track, 6.7 MB: ready in 3.2 seconds, back as a 6.5 MB MOV with the HEVC video kept, checksum unchanged. A 20 second 2560 x 1440 H.264 MP4 at 30 fps, 22.6 MB: ready in 3.3 seconds, 22.1 MB, checksum unchanged. The silent 8 second MP4 then went through Merge Video with a 24 fps clip that had no audio track: done in 25 seconds, a 16 second result with no sound.

How do I remove audio from a video?
Drop the video on the upload box at the top of this page, click Remove audio, and download the file when Silent video ready appears. The sound track is deleted and the picture is copied through as it is, so the download has the same quality and format as the original, only without sound.
How do I remove audio from an MP4 online for free?
Upload the MP4 here. There is no account, no watermark and no charge, only a limit of one file of up to 500 MB at a time. You get an MP4 back with the same picture and no sound, a little smaller than the original because the sound data is gone.
Can I remove the audio from a MOV file?
Yes, and the file stays a MOV, which matters for iPhone footage: the picture is kept exactly as the phone recorded it. If you want the result as an MP4 instead, run the silent MOV through MOV to MP4 afterwards.
Does removing the audio lower the video quality?
No. The picture is copied without being processed again, so every frame is the same as in the upload. In our tests the picture in each output matched the input exactly.
Why is the silent file only slightly smaller?
Because the only thing missing is the sound track, and the sound is small next to the picture. The sound in a phone video takes about 1 to 1.5 MB a minute; our 8 second clip dropped from 7.1 MB to 6.8 MB. To make a video much smaller it has to be rebuilt at a lower quality, which is what Compress Video does.
Can I keep the audio as a separate file?
Not from this tool, which discards it, so use Extract Audio on the original first to save the sound as an MP3, M4A or WAV, then bring the original back here to make the silent video.
Can I mute just one part of the video?
No, the whole track is removed from start to finish, and if the file has several audio tracks they all go. Cutting the section out, muting it here and merging the pieces back together doesn't work either, because Merge Video fails on a mix of clips with and without sound. To silence one part of a video, use a desktop editor.
How do I take the audio off a video on my phone?
Open this page in the phone's browser, tap Browse video, pick the clip from your camera roll and tap Remove audio. Keep the tab open while it uploads, since a long clip over mobile data takes a while; the strip itself is done a few seconds after the upload ends. Then tap Download to save the silent file.
What happens to my video after I upload it?
The upload goes from your browser to our cloud storage over a link that works for 10 minutes. Our server fetches the file from there, deletes that copy at once, and deletes its own copy of the upload as soon as the audio has been stripped. The silent file stays so you can download it; its link expires after 30 minutes and a nightly cleanup removes anything left over.
Why did removing the audio fail?
Three causes cover almost every case. A file over 500 MB or with an extension we don't accept is refused before it uploads. A file that has no picture, for example an MP3 renamed to .mp4, fails on the server with an error. And a dropped connection during the upload shows a network error; try again on a steadier line. A clip that simply has no sound track is not a failure: it comes back as it was.
