128 x 128 map-first setup
The default 128 x 128 grid matches a standard map's pixel dimensions, giving you a useful starting size for a manual build plan.
Minecraft Map Art Generator for Build Planning
Upload an image to plan a flat block layout at 128 x 128 or a multi-map size. Preview approximate block colors, check the suggested tile count, and export a PNG or material list. The preview does not reproduce the final in-game map rendering; build and fill the maps yourself.

Plan a manual Minecraft map art build
This tool converts an uploaded image into a flat grid of approximate Minecraft block colors. Use the 128 x 128 guides to estimate how many map-sized build sections and item frames your display may need, then export a material list before gathering blocks.
The conversion runs in your browser, but it is a planning approximation, not a filled-map simulator. It does not model Minecraft's final map colors or terrain-height shading, and it does not create a map.dat file. Build the layout and fill your maps in-game to check the actual result.
Map tile count
See how many 128 x 128 planning sections the chosen width and height cover before arranging an item-frame wall.
Material planning
Copy the planned block counts or export CSV before gathering resources. The list describes the approximate conversion, not a verified in-game map result.
Browser-based conversion
Image conversion, palette matching, dithering, preview, and export happen locally in the browser for faster testing.
Tools for planning a map-sized block layout
Convert an image to a block-color grid, compare map-sized sections, and export a plan for manual building.
Image to approximate block colors
Upload a picture to match its pixels against the tool's block-color palette. The preview helps plan placement but does not predict exact filled-map colors.
Single-map and multi-map presets
Start with 128 x 128 for one map-sized area, 256 x 128 for two, or 256 x 256 for a four-section wall plan.
Dithering for smoother pictures
Optional dithering spreads color-matching error across nearby pixels. Compare it with the undithered block preview before choosing a manual build plan.
Map tile stats
The stats estimate the number of 128 x 128 sections and count planned blocks by type. They do not generate or fill in-game maps.
CSV and PNG export
Download a PNG preview for sharing or a CSV material list for planning the build with friends, admins, or survival teams.
Made for build planning, not just previews
Review the preview beside planned material counts, then test a small section in Minecraft before committing to a larger build.
How to use the Minecraft Map Art Generator
Four steps from image to manual block plan
Upload the image
Choose a logo, poster, avatar, or screenshot. Simple shapes and strong contrast are easier to approximate with block colors.
Pick the map size
Use 128 x 128 for one map-sized section, 256 x 128 for two, or 256 x 256 for four.
Tune palette and dithering
Select a block palette and compare dithering settings. The colors are approximate and do not include Minecraft map-height shading.
Export the plan
Download the PNG preview or CSV material list, build the blocks manually, then fill and inspect your maps in-game.

FAQ
Minecraft Map Art Generator FAQ
Quick answers about map-sized grids, approximate block colors, manual builds, and exports.
Why does the Minecraft Map Art Generator start at 128 x 128?
A standard Minecraft map uses a 128 x 128 pixel grid. The preset provides a matching planning size, but you still need to build and fill the map in-game.
Can I create larger map walls?
Yes. Use 256 x 128 for two planning sections or 256 x 256 for four. The tile stat estimates map-sized sections; it does not place or fill maps for you.
Does this download map.dat files?
No. Downloads include a PNG preview, a CSV material list, and a single-layer ground-plan .litematic blueprint (columns +X, rows +Z, Y = 0; relative minimum corner (0, 0, 0)). The blueprint uses Litematica v6 and Java 1.20.4 data; other versions and in-game import are not verified. The tool does not create a map.dat game file or build or fill maps in your world.
Will the preview match the final in-game map exactly?
No. It approximates an image with block colors and 128 x 128 guides. Minecraft's map rendering and terrain-height shading are not simulated, so test the finished blocks with a filled map in-game.
Which images convert best?
High-contrast logos, avatars, icons, and posters are easier to approximate. Detailed photos may benefit from cropping, dithering, or a larger block plan. Choose Image fit before judging the palette. Cover fills the chosen grid and can crop the edges of the source; Contain keeps the whole image but may add margin cells when the shapes differ. Enable Keep transparency to leave those cells empty; otherwise they are matched to blocks and counted in the material list. Check that a face, logo, or caption has not lost an important edge. Enlarging the grid gives more cells to represent detail, but does not restore information missing from the original image.
Can survival players use this tool?
Yes. The CSV lists block IDs and counts for the current approximate plan, so you can estimate materials before gathering them. Read the CSV as a resource budget, not a row-by-row coordinate file. Re-export it after changing the size, palette, or dithering, because those choices can change the block counts. Keep the PNG from the same settings beside the list. Build a small test patch first and inspect its filled-map appearance before collecting materials for the entire wall. The planning grid does not choose a world position for your build.

No. This is an independent fan-made Minecraft Map Art Generator and is not affiliated with Minecraft, Mojang, or Microsoft.
