Does this work with all Gemini-generated images?

Yes. The tool supports all official Gemini image resolutions (512px to 4096px across 50+ aspect ratios). It uses an auto-detection algorithm to locate the watermark even in near-official sizes.

Will the result look different from the original?

No. This tool uses reverse alpha blending — a mathematical inversion of exactly how Gemini applies the watermark. The restored pixels are identical to what Gemini generated before the watermark was overlaid.

Is my image uploaded to any server?

Never. All processing runs 100% locally in your browser using JavaScript. Your image data never leaves your device, ensuring complete privacy.

What file formats are supported?

You can upload PNG, JPG, or WebP images. The processed result is always exported as a PNG to preserve quality.

Can this remove watermarks from non-Gemini AI images?

This tool is specifically calibrated for Google Gemini's watermark pattern and alpha map. It is unlikely to work correctly on watermarks from other AI generators (Midjourney, DALL·E, etc.) which use different blending methods.

Gemini Watermark Has Upgraded

Newer Gemini models have slightly modified watermark positions and sizes. If the default removal leaves artifacts, we highly recommend enabling the "Advanced Options" below to fine-tune the margins or use the built-in preset template for a clean result.

How It Works — Reverse Alpha Blending

No AI inpainting or guessing. Gemini watermarks are blended with a known alpha channel, which can be mathematically inverted for a perfect, lossless restoration.

Core formula

original = (watermarked − α × logo) / (1 − α)

Since the watermark's alpha map is known, the original pixel value can be computed exactly — producing lossless results impossible with AI inpainting.
