Too quiet?
Turn any tab up to 600%.

For videos recorded too low, weak laptop speakers and calls you can barely hear. A built-in limiter keeps it clean, so it gets louder without the crackle.

How it works

Three seconds, no setup.

  1. 1

    Click the knob icon.

    On the tab that’s too quiet, open Volume Booster from Chrome’s toolbar.

  2. 2

    Turn it up.

    Drag, scroll or use the arrow keys. You hear the change as you turn, up to 600%.

  3. 3

    That’s it.

    The boost stays on that tab, through new videos and in fullscreen, until you reset it.

What you get

Loud and clear.

Clean boost.

Turning sound up 6× would normally clip and crackle. The built-in limiter catches the peaks, so it just gets louder.

Modes for real problems.

Voice for mumbled dialogue and quiet calls. Bass for small laptop speakers. Night evens out loud scenes so you don’t ride the volume.

Fullscreen still works.

Many boosters break fullscreen video. Volume Booster keeps it working on YouTube, Netflix and everywhere else while the boost is on.

The level on the icon.

A boosted tab shows its level on the toolbar icon. You can also go below 100% to turn one noisy tab down.

Questions

FAQ

Is it free?

Yes. No trial, no account, no ads.

Will 600% damage my speakers or my hearing?

The limiter stops digital clipping, which protects against the harsh crackle. Very loud sound for a long time can still harm your hearing, so turn it up only as far as you need.

Do I need to reload the page?

No. The change applies right away while the page keeps playing.

Why can’t I boost some pages?

Chrome doesn’t let extensions capture sound on its own pages, like Settings or the Chrome Web Store. Any normal website works.

Can I boost two tabs at once?

One tab at a time for now. Turning the knob on another tab moves the boost there.
