About GeminiClean

A free, open, privacy-first tool for removing Google Gemini AI watermarks using mathematically precise Reverse Alpha Blending — not AI guessing.

Our Mission

Built on Transparency & Mathematical Precision

GeminiClean was created to fill a clear gap: users generating images with Google Gemini needed a reliable, trustworthy way to remove the visible watermark for legitimate personal use cases — portfolio presentation, creative projects, and design workflows.

Most "AI watermark removers" use generative inpainting — literally hallucinating new pixels to paint over the watermark region. GeminiClean does the opposite: it uses the exact mathematical inverse of the watermarking process to recover the original pixels with zero information loss.

Privacy First

Your images never touch our servers. Processing is 100% local.

Math, Not Magic

Deterministic, reproducible results based on algebra, not neural networks.

Free Forever

No paywalls, no credits, no subscriptions. Always free.

What We Stand For

Our Core Values

Privacy

We believe your images are yours. We have no interest in collecting, storing, or analyzing any data you process with our tool. Zero telemetry on image content.

Transparency

We openly explain the exact algorithm we use, its limitations, and the legal context. No black boxes, no hidden processing, no misleading claims.

Precision

Mathematical correctness over marketing claims. Our algorithm produces deterministic, reproducible results grounded in the same alpha compositing standard Gemini uses.

Accessibility

Professional image processing tools should not require a subscription or technical skills. GeminiClean works in any modern browser with a simple drag-and-drop.

Responsibility

We provide clear legal disclaimers and encourage users to comply with applicable laws. This tool is intended for legitimate personal and creative use only.

Quality

Lossless PNG output, Float32 precision calculations, and boundary smoothing — every design decision prioritizes output fidelity over processing shortcuts.
