What it is

CraftMC Minecraft Map Art Generator is a free web tool that converts PNG, JPG, and WebP images into Java Edition filled-map items for display in item frames. It supports custom rectangular walls up to 16×16 maps, or 256 maps, with each map storing 128×128 pixels. Larger images are divided at those boundaries. The preview uses Java map color IDs and four brightness shades, while generated map data is locked against ordinary terrain updates repainting the image. A ZIP export contains map data, an ID counter, tile previews, give commands, a layout, and installation instructions. Resizing, color conversion, splitting, NBT writing, and ZIP creation happen locally in the browser; CraftMC says the image is not uploaded. Installation requires access to world data folders in Java singleplayer worlds or editable servers.
