Increase the volume of a video’s audio while extracting

When the video’s sound is low, you can extract the audio already with volume gain: the page opens with +100% ticked and you can switch to +50% or Normal. The extraction happens in the browser, without sending the file.

Tips for a good result

  • In the test, +100% doubled the sound’s peak level.
  • Listen to the result in the player before downloading.

What this tool does not do

  • The gain multiplies the sound without a limiter: on audio that is already loud, the increase can distort (clip).
  • The gain also amplifies background noise.
  • The raised volume applies only to the new file; the original video does not change.
  • One video at a time, and the extraction depends on the device’s memory: very large videos may fail.
  • The video must have an audio track; if it does not, the app warns you.
  • The new file carries the “WebFaz.com” credit in the metadata (comment and artist).

Frequently asked questions

Which gain should I choose?
Start with +50%. If it is still low, use +100%. If the sound distorts, go back to a smaller value.
Does this change the video?
No. The app creates a new audio file and leaves the video as it is.
