PRIVATE BROWSER PROCESSING
Remove the audio track instead of turning the volume down
If the final video must be silent, delete the audio stream from the output instead of leaving a muted track behind. Process it locally and download a clean silent MP4.
Remove audio
Mute and remove are not quite the same thing
The output contains no audio stream at all. This is useful when privacy, upload rules or downstream editing is easier with a genuinely silent file rather than a zero-volume track.
Privacy and limitations
Processing uses FFmpeg WebAssembly locally. The video is not uploaded by this tool. Closing or refreshing the page clears the working file. Speed depends on the browser, device memory, source codec, duration, and resolution, and tools that re-encode are not lossless.
Common questions
Which video formats are supported?
The FFmpeg core handles common formats such as MP4, MOV, WebM, MKV, AVI, MPEG, M4V, 3GP, TS and WMV, though the browser may not preview every format.
Is my video uploaded to DJAI?
No. The source file is read and processed in your browser on your device.
Why can the first run take longer?
The browser downloads an FFmpeg WebAssembly core of roughly 31 MB the first time processing is needed; caching can help later runs.
