Volume Booster

Turn up the volume beyond your system's limit — up to 6× louder.

Volume Booster captures your tab's audio at the system level and amplifies it in real time. Unlike other boosters that only work on basic websites, ours works
everywhere: YouTube, Spotify, Netflix, Twitch, podcasts, video calls, and any site you can think of.

WHY CHOOSE VOLUME BOOSTER?
──────────────────────────────

✅ Works on Spotify & DRM-protected sites
Most volume boosters silently fail on Spotify, Netflix, and other streaming services because those sites protect their audio pipelines. Volume Booster captures
audio after decryption — so it works everywhere, guaranteed.

✅ Real-time slider — no reload needed
Drag the slider and hear the change instantly. Switch tabs, come back, it's still on.

✅ Per-tab memory
Each tab remembers its own volume setting. Boost your podcast tab to 300% while keeping your music tab at 150%.

✅ Zero privacy footprint
We request only the permissions we actually need:
• activeTab — to know which tab to boost
• tabCapture — to capture that tab's audio
• storage — to remember your per-tab settings

No access to your browsing history. No network requests. No data collection. Ever.

✅ No ads. No upsells. No bloat.
Open the popup, set your volume, done. That's the entire app.

TECHNICAL NOTE
──────────────────────────────

Volume Booster uses Chrome's tabCapture API — the same API used by professional screen recording tools. Audio is processed locally on your device using the Web
Audio API. Nothing leaves your machine.

Compatible with Chrome 109 and above.
