MAP ART GENERATOR
Turn any image into real Minecraft building blocks – with staircasing for a much wider color range than a flat single layer. Colors are matched against the real map colors from Minecraft 26.3, so the preview is exactly what the finished map looks like. Everything runs in your browser, no file is ever uploaded.

A thin outline in the original (a logo's red drop shadow, say) turns into a ragged line of single blocks when the image is shrunk. Here every block with too few neighbours of its own color is dropped and takes the color around it instead. Large areas are left alone. On a Minecraft map every block has one fixed color (61 of them, 3 shades each) – not the color of its texture. "Map color" matches against those, so the preview is exactly what the finished map looks like. A map art really is just the topmost layer. Carpets and slabs do need something under them to be placed though – either you lay your own floor, or you let it build full columns here. Good for photos with color gradients – for logos/text with hard edges (e.g. white/red) dithering deliberately invents in-between colors from neighboring blocks. If you want only colors that are actually in the image there: uncheck this + raise contrast instead.Preview
Each map on its own
This is how the maps hang on the wall: row by row, map 1 starts top left. Every map is 128 × 128 blocks.

Staircased uses height steps (one step up/down/same) for extra light/dark shading – this unlocks far more usable colors than a flat single layer, though the build can end up at varying heights.
Too blocky? A Minecraft map is always exactly 128×128 pixels – one pixel per block, and the game offers nothing finer. If your motif comes out too coarse, the only real fix is a bigger wall of maps: 2×2 maps are already 256×256 pixels, 3×3 are 384×384. On top of that, detail sharpness and contrast bring back edges that downscaling eats.
Besides full blocks, all 101 slabs, 97 stairs (the new wool and concrete ones too) and 18 carpets are included as well. On a map they look exactly like their full block, so the full block is always chosen automatically – with the "Slabs only" preset you build the same motif for half the material, and with "Carpets only" every cell gets a carpet on wool of the same colour.
On a map every block has exactly one fixed color (61 base colors × 3 buildable shades) – that is what the game's own code says, and it is read straight from it. When several blocks share a map color, the one whose texture is closest to the image wins: same map, better-looking build.

Official Minecraft Map Colors
The game's official base color set (62 colors, 4 brightness levels each – level 2 is the full/normal color). The map.dat file carries exactly the colors of the blocks that get built.
All Blocks & Their Color
Every block with its texture color (how it looks in the build) and its map color (how it looks on the map). Blocks that share a map color are interchangeable on a map – handy when you run short of a material.
