Safest Volume Booster door Gaurav Patidar

Volume Booster gives you a simple popup for increasing audio and video volume above the normal browser limit.

Use the slider to raise volume from 100% up to 600%, choose a quick preset, disable boosting with one toggle, or reset everything back to the default level.

Features:

• Boost audio/video volume from 100% to 600%
• Quick preset buttons for 100%, 200%, 400%, and 600%
• Popup toggle to enable or disable boosting
• Reset button for returning to normal volume
• Works through a content script on pages with standard audio or video elements

Privacy: This extension stores only your local volume preference and enabled/disabled state in browser extension storage. It does not collect, transmit, sell, or share user data. It does not use analytics, tracking scripts, external API calls, or remote code.
