FAQ
Tiled or single watermark?
Tiled deters cropping-based theft; a single bottom-right mark is cleaner for source attribution.
Will the watermark text blur?
Text is drawn vectorially at full resolution and exported as lossless PNG, staying sharp on large images.
Is my image uploaded?
No, everything runs locally in your browser.
