About Volume Booster Pro

Volume Booster Pro turns up audio that's stuck too quiet — past the browser's normal 100% ceiling, up to 600% louder. BOOST BEYOND 100% Most volume controls cap out at 100%. Volume Booster Pro uses your browser's own Web Audio engine to genuinely amplify a tab's sound, not just fake a louder-looking slider. PER-SITE MEMORY Set a boost level once per website and it's remembered automatically. Each site keeps its own setting, so you're never re-adjusting the same tab twice. LIVE, INSTANT CONTROL Drag the slider and hear the change immediately. No reload, no page refresh — the boost applies live while you watch or listen. QUICK PRESETS Jump straight to 100%, 150%, 200%, 300%, 400%, or the full 600% with one click. GLOBAL ON/OFF SWITCH Turn boosting off everywhere instantly with a single toggle, without losing your saved per-site levels. CLEAN, FOCUSED INTERFACE No clutter, no ads, no upsells — just a fast popup that gets out of your way. PRIVACY Volume Booster Pro runs entirely in your browser. It has no server, does no tracking or analytics, and never sends your audio, browsing activity, or any other data anywhere. Full privacy policy: https://github.com/gsashish-code/volume-booster-pro/blob/master/PRIVACY.md A NOTE ON SOUND QUALITY Boosting audio past 100% amplifies whatever signal the site is already sending — on already-loud sources, high boost levels can introduce distortion or clipping. That's a property of amplification, not a bug.
