About BlockMosaic

BlockMosaic is a free, browser-based toolkit for turning pictures into Minecraft blocks. It started from a simple frustration: converting an image into pixel art by hand — matching colors block by block and counting materials — takes hours. These tools do it in seconds.

What you can do here

• Image Converter — turn any photo or picture into Minecraft blocks.
• Pixel Art Generator — create murals with a live grid preview.
• Block Shopping List — get an exact block count and CSV for survival builds.
• Map Art Generator — make 128×128 map art using official map colors.

Our approach

Everything runs in your browser. Your images are never uploaded to a server — they are processed on your own device and never leave it. The tools are free to use, with no account required. We keep the site fast, simple, and focused on doing one thing well: getting you from a picture to a buildable design.

Who makes this

BlockMosaicis an independent project maintained by a small team of Minecraft players and web developers. We're not affiliated with Mojang or Microsoft — see the disclaimer below — and we build these tools because we use them ourselves.
