How to mute a video or replace its sound

  1. Drop a video, or try the sample
  2. Choose Mute, Keep & adjust (volume), My audio file or a Built-in track
  3. For your own audio, pick the file and set where it starts; mix the original underneath with the volume slider
  4. Trim the start and end, pick 720p or 1080p, and tap Make my video; it records in real time

Good to know

  • Real time: the video plays once while it is re-recorded, so a one-minute clip takes a minute. Keep the tab open.
  • Format: Chrome and Edge save MP4 on most devices; Firefox saves WebM. Instagram and WhatsApp accept both.
  • Built-in tracks are made by the browser’s synthesizer, so there is no copyright claim.

Frequently asked questions

Quick answers about the mute video / replace sound tool.

Does muting re-encode the video?

Yes, the picture is recorded again at 720p or 1080p. For a lossless mute, a desktop editor is better; for posting, this is enough.

Can I add a voice-over from a voice note?

Yes. Pick the M4A or MP3 as “My audio file”.

Is my video uploaded?

No.
