Gemini Watermark Remover powered by OneShotSEO.com — instantly clean the visible sparkle overlay from AI-generated visuals, right inside your browser. This extension restores your content to a professional state in one click using advanced reverse alpha-blending, entirely on your device. Designed for creators, designers, marketers, and developers who work with AI-generated content every day. Everything processes 100% locally — zero uploads, zero servers, zero tracking. Your privacy is fully protected. Start free with 10 images and 5 videos per day — or upgrade to Premium for unlimited access and batch support. ━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━ This extension uses reverse alpha-blending to mathematically reconstruct the original pixels hidden beneath the semi-transparent sparkle overlay. Unlike blur, crop, or inpainting tools, this approach delivers lossless results on PNG and near-lossless quality on JPEG and WebP — preserving every detail of your original creation. For AI-generated videos, each frame is processed individually using WebCodecs, ensuring smooth, artifact-free output without quality loss or flickering. ━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━ ▸ One-Click Cleanup — Upload your file and the sparkle is detected and cleaned automatically.
