Built for Nano Banana-style visible marks
The cleanup logic is tuned for a specific kind of visible white translucent mark. That narrow focus makes the tool fast and private, but it also means random logos and heavy overlays may need another editor.

FAQ
What image formats are supported?
The tool accepts JPG, PNG and WebP files.
