What It Does
Spritesheet Generator is a lightweight Windows desktop tool for creating both progress bar animations and general spritesheets. Use two images (empty + filled state) for progress bars, or import a sequence of images to combine into a spritesheet.
How It Works
Simply drop in your source images, choose a fill direction (left to right, right to left, top to bottom, or bottom to top) and a layout mode, and the tool automatically generates all intermediate frames using canvas-based rendering.
Output
The result is a clean PNG spritesheet ready to use in your game or UI, exported in one click — no external dependencies, no complicated setup.
