What is the Gemini watermark?
Images generated by Google's Gemini (including the Nano Banana image models) carry a small visible mark — usually a sparkle icon in a corner — plus an invisible SynthID watermark embedded in the pixels. This page deals with the visible corner mark that appears on free-tier exports.
Patch or crop — which should you use?
- Patch fills the selected area with a blur of its surroundings. Best when the watermark sits on sky, walls, gradients or any busy texture — the result keeps your original dimensions.
- Crop removes the entire edge strip containing the mark. Guarantees the mark is gone and needs no guessing, at the cost of a few percent of the image. Best for social posts where you're resizing anyway.
Can the invisible SynthID be removed?
No — and this page doesn't try. SynthID is embedded in the image data at generation time; editing, screenshotting or re-encoding may degrade it but there is no reliable way to strip it. If you need watermark-free AI images, the clean route is a paid tier or a model that doesn't mark outputs. Always respect Google's terms of service and local rules about AI-content disclosure — many regions now require labeling AI-generated media.
How to use (3 steps)
- Drop your image — the bottom-right corner (Gemini's default spot) is pre-selected; drag to adjust if yours differs.
- Pick patch or crop, hit Remove watermark, check the preview.
- Download the PNG. Nothing was uploaded at any point.
