Volume Booster Tab

Volume Booster Tab raises the volume of any browser tab beyond what the page itself allows, and gives you real control over how that sound is shaped.

FEATURES

• Boost from 0% to 600%, raisable to 1000% in settings • Limiter that prevents clipping and painful peaks when boosting • 6-band equalizer, 60 Hz to 10 kHz, under Advanced settings • Stereo balance, from full left to full right • Mono downmix for listening with a single earbud • Bypass switch to compare the processed and untouched sound instantly • Available in 55 languages, fully translated

EVERY TAB IS INDEPENDENT

This is the part most volume boosters get wrong. Every tab keeps its own volume, its own equalizer curve, its own balance. Run a stream at 300% in one tab and music at 120% in another; changing one never touches the other.

The toolbar badge shows the level of the tab you are looking at, so you can tell at a glance which tabs are amplified.

TEMPORARY BY DEFAULT

A boost is forgotten when you close the tab. A setting you chose for one video can never surprise you weeks later on a different page.

If you do want a site to always open at the same volume, tick "Remember this site" in the popup. The options page lists every site you have saved and lets you remove any of them, or change the default so that new tabs remember automatically.

KEEPS UP WITH STREAMING SITES

Sites like YouTube and Twitch replace their video player when you move to the next episode or stream, without reloading the page. Many boosters lose the audio at that moment and keep showing a level they are no longer applying. This one watches for the swap and reapplies your settings to the new player, so the volume you set stays the volume you get.

PRIVACY

No tracking. No analytics. No account. No network requests of any kind, not even for fonts. Your settings never leave your own machine.

WHAT IT CANNOT DO

DRM-protected services such as Netflix, Disney+, Prime Video and Spotify hide their audio from extensions by design, so they cannot be boosted. When a page cannot be processed the popup says so plainly instead of silently doing nothing.

Browser pages such as about: and the add-ons site are off limits to every extension, including this one.

PLEASE BOOST RESPONSIBLY

High volume can damage both your hearing and your speakers, especially with headphones. The limiter is on by default above 100% and you should leave it on. Raising the ceiling past 600% in settings is at your own risk.
