Volume Keeper

About

Volume Keeper gives you precise control over the sound of any website — boost quiet videos up to 600%, or turn down a too-loud tab — and it remembers the level you picked for each site automatically.

WHY IT'S DIFFERENT
• Never breaks fullscreen. Many volume boosters stop YouTube and other players from going fullscreen. Volume Keeper doesn't — it leaves the page's player untouched.
• Remembers every site. Set a site once; Volume Keeper restores that volume every time you come back. You can also set a default level for all new sites.
• No sudden blasts. Volume changes ramp smoothly instead of jumping, so you won't get a painful spike of sound.
• Anti-distortion. A built-in limiter tames the harsh clipping you get when boosting too hard (toggle it off if you prefer).
• Voice & Bass presets. Make speech clearer or add low-end warmth.
• Scroll to fine-tune. Hover the slider and scroll to nudge the volume in small steps.

PRIVACY
No accounts, no tracking, no data leaves your device. Your volume settings are stored locally in your browser. See the privacy policy linked below.

NOTES
• Works on standard HTML5 audio/video. DRM-protected players (e.g. Netflix, Disney+, Spotify) cannot be amplified due to browser restrictions.
• Chrome only.
