Gemini Watermark Remover: Remove Gemini watermarks in your browser — nothing uploads

This tool removes the visible watermark from Gemini images by reversing the exact alpha blend it was applied with, so the original pixels come back. No cropping, no AI inpainting. Everything runs in your browser and nothing is uploaded. You can check the network tab yourself: zero outgoing requests. Free, no sign-up, no limits. You can queue multiple images and download them all as one ZIP, output is lossless PNG, and it works on phones too. One honest note: only the visible logo is removed. Google's invisible SynthID watermark stays intact, so images remain detectable as AI-generated. Next up is video support, so watermarked Gemini clips can be cleaned the same way. Happy to answer questions, and if detection fails on one of your images I'd love to see it.
