CSS sprite animation uses a single sprite sheet image with animation and steps() to create frame-by-frame animations. Unlike GIF animations, sprite animations have no quality loss and allow full CSS control over speed, direction, and playback.
This tool handles everything from uploading sprite sheets or combining individual frames to auto-generating CSS animation + steps() code, all within your browser.

How CSS animation + steps() Works
steps() is a value for animation-timing-function that makes animation change in discrete steps rather than smooth interpolation. For sprite animations, it moves background-position step by step to display each frame.
