Silent dance video → add trending music for TikTok.
Wedding highlight → romantic music.
Tutorial mute → re-record voice.
How to mute or replace video audio — 4 steps
Upload your video: drag and drop or select an MP4, MOV or WEBM file up to 500 MB.
Pick a mode: choose Mute to strip the original sound, or Replace to add a new MP3, WAV or M4A track (up to 100 MB).
Adjust the length: if you replace the audio, enable auto-trim to the shorter of the video or audio so the clip ends cleanly.
Export & download: process the video and download the result — no watermark, no signup.
Use it to silence street noise before adding clean background music, swap copyrighted audio for CC0 tracks, turn a
silent clip into a TikTok-ready video with trending music, or score a wedding highlight. In Mute mode the picture is
stream-copied for zero quality loss, the tool is free with no watermark, and your uploaded files are
automatically deleted after 5 minutes.
Frequently asked questions
What is the difference between Mute and Replace mode?
Mute mode removes the original audio track and keeps the picture untouched. Replace mode swaps the original sound for a new MP3, WAV or M4A track you upload (up to 100 MB).
Will muting reduce video quality?
No. In Mute mode the video is stream-copied — the picture is not re-encoded — so there is zero quality loss and the process is nearly instant.
What happens if the new audio is longer or shorter than the video?
You can auto-trim to the shorter of the two, so the result ends cleanly when either the video or the new audio track runs out.
Which video formats and sizes are supported?
You can upload MP4, MOV and WEBM files up to 500 MB.
Is it free and are my files kept?
It is completely free with no watermark. Uploaded files are processed and then automatically deleted after 5 minutes.
