VolumeBooster: Volume & Bass Booster

Boost any tab up to 1600%, sculpt the bass, EQ, compress, widen and normalize, with a limiter that keeps it clean.

Make any tab louder without turning it into distorted mush. Most volume boosters just multiply the gain and ship the clipping. VolumeBooster ends its audio chain with a mandatory, never-bypassable true-peak limiter, so even 1600% stays clean instead of crackling.

VolumeBooster never records, stores or transmits your audio, and nothing runs on the websites you browse. The only network requests go to our payment processor to check whether you bought Pro. ONE HONEST LIMITATION Netflix, Spotify Web, Apple Music and similar protect their audio with DRM. Chrome delivers silence to every capture tool for those tabs, so no extension can boost them — including this one. VolumeBooster detects it and tells you plainly instead of pretending. Your system volume still works there. Pro: $1.99/month, $9.99/year, or $19.99 once (lifetime).
