Amplo — Volume Booster & Equalizer

Boost any tab up to 600% with a 10-band equalizer. Fullscreen keeps working. No tracking, open source.

Amplo makes quiet tabs loud and lets you shape the sound — without breaking fullscreen. VOLUME BOOSTER • Boost any tab from 0% up to 600% • Quick buttons for 100 / 200 / 300 / 400 / 600%, and mute • A limiter keeps loud boosts clean instead of crackling 10-BAND EQUALIZER • 31 Hz to 16 kHz, ±12 dB per band • Presets: bass boost, bass reduce, vocal / speech, treble boost, movie, music — or tune it yourself • Mono output for one earbud or one speaker FULLSCREEN KEEPS WORKING Most volume boosters capture the whole tab, which traps fullscreen video inside the window. Amplo processes the page's own video and audio instead, so fullscreen stays fullscreen. For the few players it cannot reach, Chrome users can switch on compatibility mode. REMEMBER PER SITE Turn on "Remember for this site" and Amplo applies your level and equalizer every time you come back. It asks for access to that one site only, at that moment. PRIVATE AND OPEN SOURCE • No data collection, no analytics, no ads, no network requests • Works on the tab you open it on; no "read all your data on all websites" warning at install • Source code: github.com/hunhunseunghun/amplo Works on YouTube, Netflix-style players, online courses, podcasts, news sites and most HTML5 video and audio.
