Free Remove Audio from Video

When a silent or partly muted video is the right fix

Many videos are fine visually but carry sound you do not want to share. A phone clip of a product demo may have traffic noise or a private conversation in the background. A screen capture may include a notification chime. A short clip for a slideshow, a looping website banner or a social post that will get its own music often works better with no audio track at all.

Selected muting helps when only a few moments are the problem. An interviewer may want to silence a name that was said by mistake, a teacher may want to cut a classroom interruption, and a small business owner may want to hide a phone number spoken in a walkthrough. The rest of the soundtrack stays in place, so viewers still hear the useful parts.

The tool accepts one MP4, MOV, WebM or MKV video at a time, up to 100 MB, 10 minutes long and 4K resolution. Work happens on your device, which suits footage you would rather not send to a remote server.

A worked example with two muted ranges

Suppose you have a two-minute file called interview.mp4 and a guest says a private address at about 12.5 seconds and again near 48 seconds. Choose Mute selected time ranges, keep MP4 as the output container and enter Range 1 as 12.5 to 15 seconds. Then play the preview to the second moment, pause at 48.00 and select Add range at playhead. The tool adds a range from 48 to 50 seconds, which you can stretch to 50.2 by editing the end value.

After you select Process video, the result is named interview-muted.mp4. The picture is copied exactly as it was. The first audio track is rebuilt with silence between 12.5 and 15 seconds and between 48 and 50.2 seconds, and it is encoded as AAC at 160 kbps. If you had chosen WebM, the audio would be encoded as Opus at the same bitrate instead.

If you choose Remove the entire audio track instead, no ranges are needed. The output keeps the first video stream and simply has no sound.

How the processing works

The first time you process a file, the page downloads a shared local media engine of about 31 MB. The video stream is then copied rather than decoded and compressed again, which is why picture quality does not change and processing is usually quick. Subtitles, data streams and file metadata are not carried into the output.

For timed muting, the engine applies a volume of zero only while the playback time falls inside each range. You can add up to 20 ranges. Audio is stored in small frames, so the silence starts and ends on frame boundaries and can differ from your typed times by a tiny fraction of a second. The finished file must stay under 150 MB.

Common mistakes to avoid

Do not rely on the typed numbers alone. Play the downloaded result and listen a little before and after each range, then widen a range if a syllable slips through. Remember that only the first audio track is kept in selected mode, so a second commentary or language track will be dropped.

Pick a container that fits the source codecs. WebM output expects VP8 or VP9 video, and some codecs will not fit in MP4. If processing fails with a compatibility message, try MKV, which accepts a wider range of codecs. Finally, end values must be later than start values and cannot run past the end of the video.
