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.

About Lunivae

Empowering Creators With Lossless Mathematical Image Clarity

Lunivae is a privacy-first web utility built to restore original pixel clarity from Google Gemini (Imagen 3) images and Google Veo AI videos using exact mathematical reverse alpha unblending.

Why We Built Lunivae

Generative AI image models have transformed creative workflows. However, watermarks automatically stamped onto high-resolution renders often ruin compositions meant for wallpapers, professional graphic design, print media, and commercial mockups.

Traditional watermark removers rely on generative AI inpainting models that smudge, guess, and hallucinate blurred textures over watermarked areas. We realized that Google applies its watermark using a deterministic linear alpha blend:

Watermarked_Pixel = (1 - α) × Original_Pixel + α × Logo_Color

By mathematically inverting this equation with pixel-exact precision, Lunivae reconstructs the authentic original photons without generating fake artifacts, preserving 100% of your source render clarity.

Zero-Server Privacy Guarantee

Unlike other tools that upload your private photos and proprietary artwork to remote cloud servers, Lunivae runs 100% locally in your browser memory using client-side HTML5 Canvas and WebAssembly.

Your media never touches any server

Zero data logging or tracking

Instant processing with zero cloud wait time
