Make a video louder, quieter or silent

Change Video Volume adjusts the sound of a video without touching the picture. Boost a quiet recording, turn down a loud one, or mute it completely to share the video without its sound.

Only the sound is re-encoded; the picture is copied as it is, so the job is quick and the video keeps full quality.

Choose a video, then set the volume, or choose Mute, then select Save and download. It's free, there's no sign-up, and it runs in your browser, so the file never leaves your device.

Good to know

  • Only the sound is re-encoded; the picture is copied as it is.
  • Boosting a quiet video a lot can make loud parts distort. Listen to the result before you share it.
  • The first time you use an audio or video tool, your browser downloads our 31 MB processing engine. It's kept for next time, so later runs start straight away.
  • This tool runs in your browser. Very large files depend on your device's memory.

Change video volume: common questions

How do I remove the sound from a video?
Choose the video, select Mute and save. The video is copied without its sound track.

Raise the volume above 100% and save. 150–200% is usually enough. Higher boosts can distort.
Does it change the video quality?
No. The picture is copied as it is.
Is Change video volume free?
Yes. Change video volume is free, works without an account and adds no watermark, for files up to 500 MB. Pro raises that to 2 GB.
Are my files uploaded to a server?
No. Change video volume runs in your web browser, so the file is read on your own device and never sent to ConvertFile.
Does Change video volume work on Mac, Windows, Android and iPhone?
Yes. It runs in any modern web browser, with nothing to install. Very large files work best on a desktop or laptop, because in-browser tools use your device's memory.
