This is manual correction, without camera profiles. Cropped or strongly fisheye photos may need another model. Zoom trims edges and cannot restore lost detail.

Details and tips
How it works
A centered one-coefficient radial mapping resamples the image with alpha-aware bilinear interpolation. Positive and negative settings bend lines in opposite directions; canvas size stays fixed.
Made for everyday images
Correct mild wide-angle curvature in architecture, product photos and photographed prints.
