A small tool for an annoying print problem.

RatioGuard helps people who prepare digital artwork or photos for several physical print shapes. A source image can look correct on screen and still lose important content when a buyer, lab or frame forces it into a different aspect ratio.

The tool focuses on three things: visual crop preview, simple resolution math, and local exports. It is intentionally not a marketplace listing manager, AI image generator or print fulfillment service.
