How to Add Rex Volume Increase in Your Own Chrome
What Is Rex Volume Increase?
Rex Volume Increase is a free Chrome extension that boosts any browser tab's volume up to 600%. It works on YouTube, Spotify, Zoom, Netflix, and any site that plays audio — with a built-in limiter that keeps sound clean and distortion-free. Best of all, it remembers your volume setting per website, so you never have to adjust it twice.
You run it entirely inside your browser. No signup, no server, no data leaves your device. Open the popup, drag the slider, and the tab gets louder instantly.
Why You Need It
Laptop speakers often max out at 100% — but that's not always loud enough. Watching a video in a busy cafe, listening to a podcast in the car, or joining a call where the other person's mic is quiet — all of these hit the same wall. Rex Volume Increase breaks past that limit safely. You get up to 6× louder audio without distortion, and it works instantly in any Chromium-based browser.

Frequently Asked Questions
- Is boosting volume above 100% safe? Yes. Rex Volume Increase uses digital gain control, not system-level amplification. You get louder sound without clipping or damage to your device.
- Does it work on Edge and Brave? Yes — it works on any Chromium-based browser, including Chrome, Edge, Brave, and Opera.
- Will it slow down my browser? No. The extension runs only when a tab plays audio and uses less than 1MB of memory.
- Can I set different volumes for different sites? Yes. It remembers your setting per domain. Set 400% for YouTube and 150% for Zoom — both work independently.
- Why isn't it on the Chrome Web Store? It's still in review. Once approved, you'll be able to install it with a single click.
