Boomly - Volume Booster

About

Boomly is a free volume booster that makes any browser tab up to 600% louder and adds a simple 3-band equalizer - so quiet videos, podcasts, and video calls come through loud and clear. Install Boomly, open the popup, drag the volume slider past 100%, and the active tab is instantly boosted.

Unlike the slider built into your video player (which stops at 100%), Boomly amplifies the real audio output of the tab using Chrome's audio engine, giving you headroom most players don't.

Features
• Boost up to 600% - go far beyond the 100% ceiling of normal players.
• One-tap presets - jump to 100%, 200%, 400%, or 600% instantly.
• 3-band equalizer - shape Bass, Mid, and Treble to cut hiss or add warmth.
• Remembers your level - your last boost and EQ settings are saved.
• Clean, lightweight UI - one slider, no clutter, no account needed.

One numeric claim
Boomly amplifies tab audio up to 6x (600%) the original volume.

How it works
Boomly captures the active tab's audio and routes it through a gain stage and equalizer, then plays the boosted result. Boosting only runs while you turn it on, and stops cleanly when you toggle it off.

FAQ

What is a volume booster?
A volume booster is a tool that increases audio output beyond the normal 100% maximum. Boomly boosts any Chrome tab up to 600%.

How do I boost volume above 100%?
Open Boomly, make sure the tab is playing audio, then drag the slider past 100% or tap a preset like 400%.

Does Boomly work on YouTube, Netflix, and video calls?
Yes - Boomly works on any tab that is playing audible audio, including streaming sites and web-based meetings.

Is Boomly free?
Yes. The core volume booster and 3-band EQ are free. A future Pro upgrade adds per-site memory and a 10-band equalizer.

Why is the boost not working?
The tab must be actively playing sound, and you must press the button in the popup (a user action is required to capture audio). Internal pages like chrome:// cannot be boosted.
