How the queue works
Files are processed in order, one at a time, so your device is never running several jobs at once. Keep the tab open until the queue finishes, since browsers, especially on phones, may pause pages in the background.
Batch mute videos

What happens to your file
A video file is a container: one track holds the picture, other tracks hold sound, subtitles or timecode. To mute a video, MuteVideo removes the audio tracks and copies the picture track exactly as it was — nothing is decoded or compressed again.
For MP4 and MOV, only the file’s index is rewritten in your browser. The picture data is referenced in place, so even large files finish in seconds without filling your device’s memory.
For WebM, MKV and AVI, an FFmpeg engine compiled to WebAssembly runs in your browser tab and performs the same stream copy.
Your video is read from your device and saved back to it. It isn’t sent to a server.
Good to know
File names you can recognize
Every result keeps its original name with a _muted suffix, so holiday.mp4 becomes holiday_muted.mp4. The silent copies can sit next to the originals without overwriting anything.
Limits per file
MP4, MOV and M4V files can be up to 4 GB each. WebM, MKV and AVI files can be up to 500 MB each on desktop and 150 MB on mobile, because they are processed in browser memory.
One ZIP or separate files
When the queue is done, download the files you need one by one or save them all as a single ZIP. The ZIP is created in your browser too, so your videos are not uploaded at any point.
MuteVideo compared with upload-based editors

| Picture quality | Copied without re-encoding | Often re-encoded on export |
| Watermark | Never | Common on free plans |
| Several videos at once | Up to 20, free | Often a paid feature |
