Frequently Asked Questions
Real questions, honest answers. If something is not covered here, the Help, Compatibility or Safety & Permissions pages go into more depth.
What is Volume Master?
Volume Master is a free Chrome extension that lets you turn the volume of any browser tab up or down — from silent to 600% — without touching any other tab or your computer’s system volume.
You get a slider for each tab, a five-band equaliser, Bass Boost, Voice Boost, Night Mode, and keyboard shortcuts. Settings are stored on your own device. Nothing is sent anywhere.
Volume Master is available now on the Chrome Web Store. The download buttons on this website point to its official store page. Its Edge listing is still in review at Microsoft Edge Add-ons.
How does Volume Master work?
You open the popup on a tab that is playing audio and move the slider. The extension captures that tab’s audio stream, raises the gain on your device, and plays it back louder. Only that tab is affected; nothing else changes.
The processing happens entirely inside Chrome on your computer. No audio leaves your machine. When you return the slider to 100% with no modes active, the extension stops running on that tab completely.
Is Volume Master free?
Yes. The current build is free to install and use. There are no ads in the popup, no premium tier, and no subscription. No account is needed — install it, pin it to the toolbar, and it works straight away.
Does Volume Master change my computer’s volume or affect other apps?
No. It works at the level of individual Chrome tabs only.
Your computer’s master volume stays exactly where it is. Other applications — music players, games, video call apps outside Chrome — are not affected. Neither are other browser windows or other tabs you are not actively boosting.
Is Volume Master safe? Does it collect any data?
The reviewed build (v1.0.3) is safe to install. It makes no network requests, contains no analytics or telemetry, and cannot read the content of any web page.
Your volume settings and preferences are stored only in Chrome’s local storage on your own device. Nothing is uploaded or shared. A full source scan of v1.0.3 on 3 November 2026 found zero network requests of any kind in the extension’s code.
Safety & Permissions — full permission-by-permission breakdown.
Does Volume Master record my audio?
No. The extension captures a tab’s audio stream to process and play it back louder. That is the only thing that happens to the audio.
It is never recorded to disk, never stored anywhere, and never transmitted. No code path for recording or sending audio exists in the reviewed build (v1.0.3, source-scanned 3 November 2026).
Can Volume Master damage my computer, speakers or hearing?
It cannot damage your computer or operating system — it processes audio in software only.
Speakers and headphones are a different matter. Any sustained, very loud audio can physically stress speakers and cause hearing fatigue or, over time, hearing damage. Volume Master shows a warning when the slider goes above 300%: “Very loud can hurt hearing and speakers.” Take that warning seriously. Start at a moderate level, raise gradually, and lower the slider if you hear buzzing or distortion.
Why can’t I go full screen while Volume Master is active?
This is expected behaviour, not a bug.
When Volume Master is processing a tab’s audio, Chrome does not permit that tab to use true full screen. The video fills the browser window, but the tab bar and address bar stay visible. This is a Chrome audio-capture rule that applies to every extension that processes tab audio — not only Volume Master.
To restore true full screen: open the Volume Master popup and press Reset, which stops the boost and releases the audio. Full screen then works as normal.
Why does a blue dot or sharing icon appear on the tab?
That icon is Chrome telling you that an extension is processing the tab’s audio — it is a security feature, not evidence of screen sharing or spying.
Chrome shows the capture indicator on any tab whose audio an extension is currently handling. Volume Master triggers it because it captures the audio stream of the tab you are boosting. The indicator disappears when you stop the boost.
Where is the Volume Master icon?
The icon appears in the Chrome toolbar, to the right of the address bar. If you cannot see it, it may be hidden in Chrome’s extension menu.
Click the puzzle-piece icon in the toolbar, find Volume Master in the list, and click the pin next to it. The icon will then stay visible in the toolbar at all times. The badge on the icon shows the current boost level for the active tab.
Why is Volume Master not working?
The most common causes:
The tab may not be playing audio yet — start the audio first, then open the popup. Chrome’s own internal pages (the Settings page, the Chrome Web Store, any chrome:// address) cannot be boosted; the popup disables itself there. Some streams are protected by DRM and cannot be captured by any extension.
If the extension was disabled after a Chrome update, go to chrome://extensions, find Volume Master, and switch it back on. Then reload the tab and reopen the popup.
Help — full troubleshooting guide.
Does it cause audio distortion?
It can, depending on the source audio and how high you set the boost.
Volume Master includes Clean Boost — a soft limiter that is on by default. It rounds the loudest audio peaks instead of cutting them flat, which reduces the harsh distortion that plain boosters produce at high levels. The difference is most noticeable above 300%.
No setting is fully distortion-free with all source material. A quietly recorded source boosts more cleanly than one that is already loud and compressed. If distortion bothers you, lower the slider.
Does Volume Master work on Netflix or other streaming services?
Not on protected streams. Chrome blocks audio capture for DRM-protected content — this applies to every extension that uses tab audio capture, not only Volume Master. It is a Chrome platform rule, and there is no workaround.
For regular, non-DRM audio on standard web pages, the extension works as normal.
Compatibility — full list of what can and cannot be boosted.
Is there a Firefox, Safari or mobile version?
No. Volume Master is a desktop Chrome extension only.
There is no Firefox version, no Safari version, and no mobile app for Android or iOS. The extension does not run on mobile Chrome either. Edge, Brave and Opera are Chromium-based browsers, and Volume Master has been tested and works in them. If you need a volume booster for Firefox or mobile, you will need a different tool.
How do I install it? When will it be available?
Volume Master is live on the Chrome Web Store: open Volume Master on the Chrome Web Store, click the add button, then confirm to add the extension. Its Edge listing is still in review at Microsoft Edge Add-ons.
Does the boost stay on when I reload or navigate to a new page?
Yes, in the current build (v1.0.3).
If a tab reloads or you navigate to a different page, the extension automatically resumes boosting at your saved level. The boost only stops if you press Reset, return the slider to 100% with Default mode active, or close the tab.
There are several extensions called “Volume Master” — which one is this?
This is the independent Volume Master extension published from volumemasterr.com — not affiliated with any other developer sharing the name. Other extensions on both Chrome and Firefox use the name “Volume Master” and are entirely different software. If a review describes features that do not match what you see in the popup, it is describing a different product. You can confirm you have the right one by checking its extension ID on the store page: ours is cihnglfgpnpecgplmbiiglaegpaaceoh. If the ID is different, it is a different extension.
