TWO MODES

PROGRESS BAR

Load an empty (background) and a full (filled) image. The app generates all 

the intermediate frames by progressively revealing the full image over the 

empty one — perfect for animated health bars, loading bars, and charge meters.

SPRITE SHEET

Drag in any number of images, reorder them, and pack them into a single 

horizontal or vertical sprite sheet ready to drop into your engine.
