01 / Local repair

Where the mark usually sits

Gemini's sparkle mark is typically small and placed near the bottom-right corner of the image. The "Nano Banana sparkle" preset on this page is sized and positioned for that common case — pick it, nudge the box if needed, and remove.

Frequently asked questions

What is "Nano Banana"?

A widely used community nickname for Google Gemini's image generation model. This page is not affiliated with or endorsed by Google.

Does this upload my image to Google or anywhere else?

No. The fill runs entirely in your browser. Nothing is uploaded.

Will the preset always land exactly on the mark?

It targets the common bottom-right placement, but exact position can vary by image. Drag the box afterward if it needs adjusting — the preset is a starting point, not a detector.

Does this work on any background?

It works best on regions with simple, repeating backgrounds — sky, walls, solid colors. Busy or highly detailed backgrounds are harder to reconstruct convincingly, so always check the preview before downloading.
