Images made with Gemini, including Nano Banana (Gemini 2.5 Flash Image), carry a small sparkle watermark in the bottom-right corner. Google also embeds SynthID, an invisible mark, which stays in place. This tool removes the visible sparkle.
It is handy when a Gemini image is going onto a slide, a thumbnail or a mockup where the corner logo distracts. Draw a box over the sparkle and the tool fills that area from the surrounding pixels.
Nothing is sent anywhere. The image is processed locally in your browser and saved back as PNG or JPG at the original resolution, with no new watermark added.
Keep the box small
The sparkle is only a few dozen pixels wide. A tight box with a small margin blends far better than a large one.
Save as PNG for graphics
Choose PNG for illustrations, text and flat colours to avoid compression artefacts. JPG is fine for photos and keeps the file smaller.
Plain corners fill best
If the sparkle sits on fine detail such as hair or text, the fill can look soft. Switch to Blur, or crop a few pixels off that edge instead.
