X and Y locate the scaled overlay’s upper-left corner before rotation. Centering overrides the corresponding coordinate. Rotation and flips act around its center; positive angles turn clockwise, and the counterclockwise checkbox reverses the angle. Overlay opacity 0 hides it; 100 preserves its original alpha, including transparent pixels.
Defaults: X=20, Y=20, scale=100%, angle=0°, opacity=80%. Empty or non-finite fields use these defaults. Finite values are clamped to X/Y −10000…10000, scale 1…1000%, angle −360…360°, and opacity 0…100%.
Each image may be at most 25 MiB and 24 million pixels; the pair may total at most 40 million pixels. Processing stays in this browser. Canvas dimensions or memory can still prevent export below these limits. The flattened PNG keeps the base dimensions and clips anything outside them. It contains no editable overlay layer; source metadata or animation may be lost.
Processing takes place locally in your browser.
