Pixel Surgeon

What this does

Pixel Surgeon cleans your Pixel Art of JPEG artifacts, anti-aliasing, dithers, cell-padding and more! Each Grid Cell is mapped and filled by majority color if it passes the customizable transparency tolerance. Then you can paint or erase cell-by-cell with Better-Than-Aseprite Pencil tools.
