Volume Booster Chrome extension

Volume Booster is a lightweight extension that adds a slider to raise a browser tab's audio past Chrome's default maximum volume. It's best for quiet videos or calls where the source audio itself is too low. The catch: it amplifies whatever audio exists, so distortion increases at higher boost levels, and it only affects the active tab.

  • no account or setup required to start boosting

What Volume Booster does

Volume Booster adds a control that amplifies a browser tab's audio output past Chrome's normal maximum, which is useful when a video, call, or stream's source audio is too quiet even at full system volume. It works on a per-tab basis, so you turn it on for the tab that needs the boost rather than changing your whole computer's audio.

How to get the best results from Volume Booster

Because the extension amplifies existing audio rather than improving its quality, pushing the slider too high can introduce distortion or crackling, especially with already-compressed audio like video calls. Start with a small boost and increase gradually, and expect diminishing returns once the source audio's own limitations become audible.

Volume Booster: FAQs

Does Volume Booster cost anything to install?

No. The Chrome Web Store lists it as free, and the boost slider works straight after install with no account. Check the store listing again if you ever see a prompt asking for payment.

What access does Volume Booster need to raise a tab's sound?

It needs access to the audio of the tabs you boost, which is inherent to how amplification works. Read the permission list on its Chrome Web Store page before installing, and remove it if you stop using it.

What is the quickest way to boost one quiet video with Volume Booster?

Open the video's tab, click the toolbar icon, and drag the slider up in small steps until speech is clear. Stop as soon as you hear crackling, then step back a notch.

Why does a quiet recording sound harsh after I boost it?

Boosting raises background noise and any clipping in the recording along with the voice. A thin or heavily compressed source has little headroom, so harshness appears well before the slider maxes out.

Do I have to boost each tab separately in Volume Booster?

Yes. The boost applies only to the tab you set it on, so a second tab playing audio stays at its normal level until you open the icon there too.

Volume Booster or my system volume: which should I turn up first?

Raise the system volume first. Reach for Volume Booster only when a tab is still too quiet at full system volume, since it changes just that tab and leaves other apps alone.

Why can't I hear any difference after moving the Volume Booster slider?

Confirm the slider was set on the tab that is actually playing, then check it hasn't reset. If the source is very quiet or heavily compressed, extra boost adds noise before it adds loudness.

Does Volume Booster affect video call software?

It can boost audio in a browser-based call tab, but it doesn't affect desktop calling apps running outside the browser.

How high is too high on the Volume Booster slider?

There is no universal safe number, because it depends on the clip and your speakers or headphones. Raise it gradually, avoid testing with headphones on your ears, and lower it before the next loud clip.

Does Volume Booster reset when I close the tab?

Boost settings are generally tied to the tab or site you applied them to and may need to be reapplied on a fresh page load.
