RP Spritesheet Editor is a professional Unity Editor extension designed to give developers more control over sprite sheets without leaving the Unity Editor.

Go beyond basic sprite slicing with a streamlined workflow for slicing, repacking, modifying, and previewing sprite sheets. Simply drag and drop your sprite sheets into the editor and start working.

The tool automatically calculates a slicing grid for imported sheets, while allowing you to manually override the column and row count whenever necessary. Sprite sheets can also be repacked into a specified number of rows and previewed before the changes are applied.
