PixelFix

Blurry pixel edges, colors bleeding into each other, anti-aliasing where there shouldn't be any. It looks fine as a thumbnail and falls apart the moment you try to actually use it.

PixelFix fixes that. It snaps everything onto a clean pixel grid, merges colors that should be identical, and sharpens up edges so the result looks like it was made intentionally and not like it crawled out of a diffusion model.

You also get palette locking (PICO-8, Game Boy, and more), resizing that respects the grid, and sprite sheet export, all in one place.
