Extends the cleaned area outward so soft watermark halos are caught.
More iterations = smoother fill on large regions. Small logos look good around 200.
Inside the selected box we solve a Laplace equation whose boundary values come from the pixels around the watermark. The result is a smooth gradient that blends with the surroundings, no blur and no streaks. Everything outside the box stays byte-for-byte identical to your original.
Best results for:
- • Gemini generated images with the bottom-right AI logo
- • Google AI Studio / Nano Banana watermark
- • Portraits, landscapes and product shots from Gemini
- • Logos on relatively uniform or gradient backgrounds
- • Small corner badges from AI image generators
