Sprite Arsenal — sprite sheet to GIF

The problem

Turning a sprite sheet into a usable animated GIF means firing up heavy software or sketchy online converters that upload your art to someone else's server.

The build

Drop in a sprite sheet, slice it, preview the animation live, and export a GIF or individual frames — entirely in your browser. Free, no sign-up, nothing uploaded.
