How to use Audio Volume Booster
- Choose an audio file.
- Pick how much louder (1.5x, 2x or 3x).
- Click Process Audio.
- Download the louder audio as WAV.
Note: boosting volume multiplies the sound. Very high boosts can cause distortion (clipping) on loud parts — the tool warns you if clipping happens. Output is WAV.
Frequently Asked Questions
Is the Audio Volume Booster free?
Yes, it is 100% free with no sign-up. Your files and data stay in your browser.
How much louder can I make it?
Up to 3x. Above that, most recordings distort badly.

No. This tool runs entirely in your browser — your file is never uploaded.
Will boosting cause distortion?
It can, if loud parts hit the maximum level. The tool tells you how much clipping happened so you can pick a lower boost.
