Common Questions & Answers
Find out all the essential details about Gemini Watermark Remover.
Is Gemini Watermark Remover free to use?
Yes, completely free! Unlike other tools on our platform, Gemini Watermark Remover doesn't consume any credits. You can use it unlimited times.
How does the watermark removal work?
We use a mathematically accurate reverse alpha blending algorithm. Gemini adds watermarks using alpha blending, and we reverse this process to restore the original pixels. This means the removal is pixel-perfect, not just an approximation.
Is my image uploaded to your servers?
No, all processing happens entirely in your browser using JavaScript and Canvas API. Your images never leave your device, ensuring complete privacy.
Which Gemini watermarks are supported?
This tool removes visible watermarks from images generated by Google Gemini AI (including Gemini Nano, Flash, and Pro). It detects both 48x48 and 96x96 watermark sizes automatically.
Does this remove invisible SynthID watermarks?
No, this tool only removes visible watermarks. SynthID is an invisible watermarking technology embedded during image generation and cannot be removed without destroying the image.
Why does Google add a visible watermark to Gemini images?
Google adds a visible watermark (the Gemini sparkle logo) to images generated by free-tier and Google AI Pro users to help identify AI-generated content. Google AI Ultra subscribers do not have visible watermarks on their generated images, though all Gemini images still contain the invisible SynthID digital watermark.
