Full-mute

Removes the audio stream entirely with -an. Instant and lossless on the video.

Range-mute

Sets volume=0 between the chosen start/end times. The audio stream stays but is silent in that range.

Start / End (sec)

Range bounds for partial-mute mode.

Common pitfalls

Symptom: File size barely changed after mute

Cause: Audio is a tiny fraction of total bytes — usually 5–15%.

Fix: For real size reduction use the Compress tool instead.

Symptom: Click at the boundary of a range mute

Cause: Sharp on/off transitions in volume.

Fix: Extend the range slightly into a natural pause to mask the transition.

Symptom: Don't know the difference between modes

Cause: Both produce a "silent" video, but full-mute removes the track entirely while range-mute keeps the track at volume 0.

Fix: Pick full-mute when you want a "no audio track" file; range-mute when you only need silence in part of the timeline.

Equivalent FFmpeg commands

Reference commands you can run on the desktop FFmpeg CLI.

Full-mute (instant, lossless)

ffmpeg -i input.mp4 -c:v copy -an -movflags +faststart output.mp4

Mute seconds 5–15 only

ffmpeg -i input.mp4 -c:v copy -af "volume=enable='between(t,5,15)':volume=0" -c:a aac -b:a 128k output.mp4

Drop one of multiple audio tracks

ffmpeg -i input.mp4 -map 0:v -map 0:a:0 -c copy output.mp4

Keeps audio track 0, drops the rest.

Browser support & limits

Recommended max: 500 MB
Range-mute re-encodes the audio (AAC); video stays untouched

Frequently asked questions

Will the player show "no audio track" after muting?

In full-mute mode, yes (the audio stream is dropped with -an). In range-mute, the audio track remains and the player shows volume controls — only the chosen range is silent.

I want to add new BGM later

Run full-mute first → drop the result into the [BGM tool](/en/tools/bgm/) to layer in music. Standard workflow.

Does video quality drop?

No. Video uses -c:v copy and is not re-encoded.

Can I lower volume instead of muting?

This tool is binary 0/100. For arbitrary volume use desktop FFmpeg with volume=0.3 (30% etc.).

How fast is full-mute?

About 5–10 seconds for a 500 MB video — only the audio is dropped, no re-encode of the video stream.
