Mute Video removes the audio track inside your browser with FFmpeg.wasm. The source file is written to the browser's local FFmpeg filesystem, processed there, and returned as an MP4 download. Convertful never receives the video.
When a video stream can be copied into MP4 safely, the tool avoids re-encoding so the picture quality stays unchanged. If the source container or codec is not MP4-friendly, Auto mode falls back to transcoding.
Muted exports are useful for social clips, demos, screen recordings, and privacy cleanup. Always preview the result before publishing because unusual codecs or damaged files can fail locally or need transcoding.
No. The source video is written to the local FFmpeg.wasm filesystem in your browser, muted there, and returned as a browser download.
When the video stream can be copied into MP4, quality stays the same because only the audio track is removed. If the source needs transcoding, the selected quality controls the new MP4.
The tool accepts common MP4, MOV, WebM, MKV, AVI, and M4V files that the browser FFmpeg build can decode. Corrupt or unusual codecs may fail locally.
Yes. Use Cancel while processing is running. Convertful terminates the in-browser FFmpeg worker so you can try a smaller file or a different mode.
MP4 is the most portable muted-video output for browsers, phones, social platforms, and editors. Some source containers are transcoded to make that MP4 playable.
