How does Reverse Alpha Blending remove Gemini watermarks without blur?

Traditional AI inpainting guesses and repaints missing pixels, which creates soft edges and blur. Google Gemini applies its watermark as a transparent mathematical overlay. Our tool reverses this linear compositing formula to mathematically recover the exact original background pixels underneath.

Are my images uploaded to any remote server?

No. All processing happens 100% locally inside your web browser using HTML5 Canvas and Web Workers. Your images never leave your computer or phone, ensuring total privacy.

What if my image was resized and leaves a faint watermark outline?

Our application features a built-in Fallback AI Healing Brush. If mathematical alpha restoration leaves any faint residual line due to external compression or resizing, you can use the brush to instantly blend and erase it in seconds.

Does this tool strip invisible SynthID and C2PA AI metadata?

Yes. In addition to removing the visible sparkle logo, you can enable our SynthID & Metadata Scrubber, which strips all C2PA provenance manifests and applies subtle spatial perturbation to neutralize invisible steganographic signatures.

Can I process large batches of images at once?

Yes. You can drag and drop multiple images or entire folders. Multi-threaded Web Workers process them in parallel and package the clean files into a structured ZIP archive for one-click download.
