Pixel Art & Block Palette

Turn an image into a block mosaic with a ready .mcfunction, and find the vanilla blocks closest to any colour. Matched in CIELAB against the real textures.

Quick guides

How to use this tool, and the questions players ask most.

How many pixels are in a Minecraft block?

Standard vanilla Minecraft block textures measure 16x16 pixels per face, totalling 256 pixels per surface. High-definition resource packs can scale individual block faces up to 512x512 or 1024x1024 pixels without altering in-world block coordinates.

How to put pixel art into Minecraft with commands?

Place your generated /setblock lines into a .mcfunction text file inside a datapack directory at data/custom/function/. In Minecraft Java Edition 1.21, execute /function custom:art in chat or via a command block to generate the build.

What size is a

map art canvas in Minecraft?

A standard level 0 map covers a flat grid of 128x128 blocks, requiring exactly 16384 individual blocks to fill completely. Map pixels render dynamically across 61 base color IDs when viewed on an in-game map item.

Which Minecraft blocks are best for solid color pixel art?

Concrete blocks such as white_concrete and black_concrete are ideal because they have flat textures with minimal color noise. Terracotta and wool blocks add surface pattern variance and introduce a natural +10% to +25% brown or grey undertone.

How do pixel art block converters match image colors?

Converters compare image pixels against the average texture color of vanilla blocks using the CIELAB Delta E*ab formula. This perceptual color-difference metric determines the closest visual match across all 1.21 survival blocks, which is what this Pixel Art & Block Palette tool calculates.
