Amplio – Volume Booster & Mixer

Volume booster up to 600% with distortion protection, a mixer for every playing tab, and an equalizer. No ads, no tracking.

Amplio makes quiet tabs loud enough, keeps the sound clean and remembers your level for every site. What it does • Boost any tab up to 600% with a slider, a preset or a typed number. Pro goes up to 1000%. • A built-in limiter, on by default and free, with a clear Safe, Limiting or Clipping indicator. • Remembers the volume for each site and applies it when a page loads, reloads or navigates. • Tab mixer: every tab that is playing sound, each with a slider, a mute button and a one-click jump. • 5-band equalizer with six presets (flat, bass boost, voice, treble, night-friendly, music), plus mono audio and left/right balance. • Keyboard shortcuts and a small on-screen display, also in fullscreen. • A one-time notice above 300% and a quick way back to a safe level. • 8 languages, light and dark themes. Honest about the limits Some audio cannot be boosted. Streaming services with DRM protection, and some media embedded from other websites, can only be changed up to 100%. Amplio tells you why instead of failing silently. Browser pages and extension stores block every extension. Privacy No ads, no analytics, no tracking, no remote code and no account for the free version. Audio is processed inside your browser and never leaves it. Amplio runs a small script on web pages to find audio and video, which your browser may describe as “read and change all your data on all websites”. The script only works with audio and video. Free and Pro The core is free. Pro is an optional subscription ($2.99 per month or $29.99 per year) that adds boost up to 1000%, a 10-band equalizer with custom presets, a loudness normalizer, night mode, voice clarity, mixer solo and groups, saved equalizers for unlimited sites and priority support. Nothing that is free today will move behind the paywall.
