Spritesheet Spacer

Grid = semi-transparent yellow lines using the current “Input spacing” and “Y offset”.

Result (updates as you move sliders)

Input spacing (tile size px) 16

Output spacing (grid step px) 32

Y offset of first sprite (px from top) 0

Assumptions: sprites are square (tile width = tile height = Input spacing). The Y offset aligns the first sprite row in the source; output starts at top-left without offset. Sprites are not scaled; larger “Output spacing” just adds padding between them.
