A volume booster that protects your audio from clipping
Cranking up gain on a quiet recording usually comes with a catch — push it too far and the loudest parts turn into harsh, crackly distortion. This tool measures your file's current peak level, applies your chosen boost, and runs a soft-knee limiter over the result so peaks are rounded off smoothly instead of hard-clipped.
Not sure how much boost is safe? Use "Auto-max," which calculates the exact amount of gain that brings your loudest moment right up to the edge without going over.

Frequently asked questions
Is this volume booster free?+
Yes — boost as many files as you want, with no sign-up and no limits.
Will boosting distort my audio?+
Not with the limiter on (default). It smoothly rounds off any peak that would otherwise clip. Turning the limiter off applies raw gain with hard clipping instead, which can sound harsh at high boost levels.
What does "Auto-max" do?+
It measures the loudest point in your file and calculates the exact boost that brings it right up to full volume without going over — the maximum safe boost for that specific file.
Is my file uploaded anywhere?+
No. Everything is processed locally in your browser and never leaves your device.
