Media Enhancer par ExtensionWizzard

Local Media Enhancer lets you fine-tune how videos and images look on any website — no account, no server, no data ever leaving your browser.

FEATURES
• Brightness, Contrast, Saturation sliders
• Warmth (cool ↔ warm color temperature)
• Sharpen / HDR Boost
• Tone presets: Grayscale, Sepia, Invert
• Video playback speed control
• Per-tab enhancement toggle — turn it on or off independently for each tab
• Automatically detects new videos/images as you scroll or as pages update dynamically
• Your settings are remembered between sessions

HOW IT WORKS
All enhancement happens locally using hardware-accelerated CSS filters applied directly to media elements on the page. Nothing is uploaded, tracked, or sent anywhere — there is no backend, no analytics, no network requests of any kind.

PRIVACY
This extension collects no data whatsoever. It requests access to all websites only because it needs to apply visual filters directly on the page you're viewing — it does not read, store, or transmit page content, browsing history, or any personal information.
