How to increase the volume of a video

Open a video, drag the volume up or down, and save the copy. This video volume booster runs in your browser, so the video is never uploaded, and the waveform shows how loud each part will be before you export.

  1. Step 1

    Choose a video
    Pick a file or drop it into the volume booster above.
  2. Step 2

    Set the volume
    Drag it up or down, or pick a preset.
  3. Step 3

    Download the video
    Save the copy with the new volume.

What to expect

Supported inputs
Any video or sound file this browser’s engine can read, with a sound track it can decode.
What happens
Every sound track is turned up or down by the amount you choose and re-encoded. Turned up, peaks that would go past full volume are held just under it, so the louder sound doesn’t crackle or clip. The picture is copied as it is, and the file keeps its format.
Limits
Volume goes from 0 to 400%. Very quiet recordings get louder, but their background hiss gets louder with them.
