Common questions
What image formats are supported?
PNG, JPEG, WebP, GIF, and BMP. Transparency is preserved for PNGs and WebP.
How does the packing algorithm work?
Choose between Shelf, MaxRects, or Grid. MaxRects usually gives the tightest fit.
Is there a limit on image count?
No hard limit. For very large sets, enable multipack to split across multiple atlases.
Does it detect duplicate sprites?
Yes — enable alias detection to merge identical images and save atlas space.
