Remove audio from MP4 use cases
When to mute an MP4 before sharing
Mute MP4s before attaching them to support tickets, uploading product demos, or posting clips where background sound would feel unprofessional.
Browser processing vs upload-based tools
For MP4 muting, a browser-first workflow can be much quicker because there is no upload progress bar and no remote processing queue.

FAQ
Can I remove audio from MP4 without losing quality?
Yes. For audio-only removal, the tool is designed to copy the video stream and remove the audio track instead of re-encoding the picture.
Does this work with large MP4 files?
Desktop browsers can handle files up to 500 MB. Mobile browsers use a lower 150 MB limit to avoid memory crashes.
Is my video uploaded anywhere?
No. The file is processed locally in your browser using WebAssembly. Nothing leaves your device.
Which file formats are supported?
MP4, MOV, and WEBM up to 500 MB on desktop and 150 MB on mobile.
Is there a watermark?
No. The exported video is identical to your file with the requested change applied.
