How do I remove the audio from a video?
To remove the sound from a video, open FixDoks's Mute Video tool, select the file, then click Remove audio. The tool drops every audio track and copies the video stream unchanged, so it finishes in seconds even for large files. Processing happens inside your browser, the video is never uploaded, and the output keeps the same format as the original.

- Click Remove audio.
- Preview the silent video and download it.
Remove the sound, keep the picture
This tool takes your video, drops every audio track, and writes the video stream into a new file exactly as it was. Because nothing is re-encoded, the picture quality is identical, the process takes only a few seconds even for large files, and the output format stays the same as the input: an MP4 stays MP4, a MOV stays MOV.
Why remove audio from a video?
- Background noise: wind, traffic or a noisy room can ruin an otherwise good clip.
- Private conversations captured by accident in the background of a family or work video.
- Copyright: music playing in the background can get a video blocked or muted on social platforms. Removing it lets you add licensed music instead.
- Product and property videos for listings, where sound adds nothing.
- Presentations and websites: silent background videos autoplay reliably in browsers, and many slide tools need a muted clip.
- Smaller files: the audio track typically takes 2 to 10 percent of the file.
Muting vs lowering the volume
Muting in a player only affects playback on your device; the sound is still in the file and plays for anyone you send it to. This tool removes the audio data completely, so the video is silent everywhere.
Keep the audio separately
If you want both a silent video and the sound, first save the audio with MP4 to MP3, then mute the video here. To cut the video shorter as well, use Trim Video, and to shrink it for sharing, use Compress Video (which also has a Remove audio option).
Supported formats
MP4, MOV, M4V, WebM, MKV, AVI and 3GP, up to 200 MB. Other formats are saved as MKV so the original video stream can still be copied without re-encoding.
Private by design
The video stays on your device. FixDoks processes it inside your browser and never uploads it, which matters when the clip shows your home, your family or your workplace.
Adding different sound afterwards
Once the video is silent, you can add a new soundtrack in a free editor such as CapCut, iMovie, Clipchamp or the Photos app on Windows. Many social apps also let you add licensed music directly when posting, and they work more reliably with a clip that has no competing audio.
If the original sound is only needed as a reference, save it with Audio Converter before you mute.
