Mute Video

What this tool does

Mute Video strips every audio track from MP4, MOV, MKV, WebM and AVI files. By default the video stream is copied unchanged, so the result has exactly the original picture quality and is ready in seconds; an optional re-encode produces a universally playable H.264 MP4.

Background chatter, wind noise, a television in the next room or copyrighted music can make an otherwise good clip unusable. Platforms may mute or block videos with unlicensed music, and silent loops are often wanted for website backgrounds, presentations and product pages.

This tool uses FFmpeg compiled to WebAssembly to write a new file containing only the video stream. Because the video is stream-copied rather than decoded and re-encoded, there is no generation loss and even long clips finish in a few seconds. The file usually becomes a little smaller as well, by the size of the audio track. Processing happens in your browser; the files are not uploaded.

How to use Mute Video

1. Drop one or more videos onto the upload area, or click to browse.
2. Leave “Re-encode to MP4 (H.264)” off for the fastest, lossless result.
3. Turn it on only if the original format will not play where you need it.
4. Click Remove audio.
5. Play the result to confirm it is silent.
6. Download each file, or download all of them as a ZIP.

Tips for better results

• Muted MP4 loops are much lighter than GIFs for website hero sections; add the muted and autoplay attributes to the video tag.
• Browsers only autoplay video without sound, so removing the audio track also avoids the sound prompt entirely.
• If you want to replace the sound rather than remove it, mute the clip here and add new audio in your editor.
• Need just the audio instead? Use Extract Audio from Video.

Common use cases

• Removing copyrighted background music before posting a clip.
• Creating a silent background video for a website or presentation.
• Stripping private conversations from a video before sharing it.
• Preparing B-roll footage that will get a new soundtrack.

Common mistakes to avoid

• Turning on re-encode for files that already play fine; it is slower and slightly lossy.
• Expecting muting to compress the file dramatically; video makes up most of the size.
• Muting the only copy: keep the original if you might need the sound later.
