Uses a pre-captured reference of the Gemini star watermark for exact alpha values. No guesswork, works on all backgrounds including grey and monochrome.
For watermarks in unusual positions or non-standard formats, paint mode samples surrounding pixels and blends them inward.
Google Gemini adds a four-pointed star watermark to AI-generated images using alpha compositing:pixel = original x (1 - α) + white x α. This blends a white star onto your image with varying transparency.
Auto mode uses a pre-captured reference template of the Gemini star to get the exact alpha values at every pixel. With the known alpha map, it reverses the compositing formula:original = (pixel - α x 255) / (1 - α). Because the alpha is known (not estimated), results are pixel-perfect on every background color, including grey.
Paint mode lets you brush over visible text overlays, logos, or watermarks in non-standard positions. The algorithm fills the masked area by sampling surrounding pixels and blending them inward from the edges with a feathered transition for seamless results.
Note: Google's SynthID is a separate invisible digital watermark embedded in pixel data. It cannot be removed by any image editor. This tool targets the visible star watermark and overlays.
This tool is for personal use on images you own or have rights to edit. Removing watermarks from copyrighted images may violate intellectual property laws. Use responsibly.
Use this Gemini watermark remover free online to remove the visible Gemini star from AI images you own or have permission to edit. Auto mode finds Google's standard 48px or 96px star in the bottom-right corner and reconstructs the marked pixels from nearby clean image data. For visible text, logos, or marks in another position, Paint mode lets you select the exact area to repair. Your PNG, JPEG, or WebP file is processed locally in your browser and never uploaded. Add an image up to 50MB, compare the original and cleaned result with the before-and-after slider, then download a full-resolution PNG that keeps the original dimensions. The free Gemini watermark remover also handles the visible star on images from Gemini models commonly called Nano Banana. It does not remove Google's separate invisible SynthID signal.
