MinecraftPixelArt.com is a free, browser-based tool that turns any photograph, drawing or logo into Minecraft block art. You upload an image, choose how many blocks wide and tall you want the finished build to be, and the tool works out which Minecraft block is the closest colour match for every single position in that grid.
Why we built it
Pixel art is one of the most popular things people build in Minecraft, and one of the most tedious to plan. Working out by eye which of nearly two hundred blocks matches a particular shade of skin tone or sky is slow, and getting it wrong means tearing down hours of work. Existing converters were either desktop applications that needed installing, or they produced a flat picture with no way to fix the parts the algorithm got wrong.
We wanted something that ran in a browser on any device, gave you a real editor to correct the output, and told you exactly how many of each block you would need before you started digging.
How the tool works
Every Minecraft block in our database is stored with its average colour converted into the CIELAB colour space. CIELAB is designed so that the mathematical distance between two colours roughly matches how different they look to a human eye, which is not true of plain RGB. For each pixel of your resized image we measure the distance to every block in the selected palette and pick the nearest one. Optional Floyd–Steinberg dithering spreads the leftover colour error into neighbouring pixels, which lets a limited palette imitate shades it does not actually contain.
All of this runs inside your own browser using JavaScript and a Web Worker. Your image is never uploaded to us, never stored on a server, and never seen by anyone but you.
What you can do with it
- Convert any PNG, JPG, BMP or WEBP image into a Minecraft block grid up to 1024 × 1024 blocks
- Crop and reframe your image before converting, so the subject fills the build
- Restrict the palette to survival-obtainable blocks, or hand-pick individual blocks
- Exclude gravity-affected, transparent, redstone-powered or light-emitting blocks
- Fix the result in a full editor with pencil, brush, bucket fill, eyedropper, bulk block replacement and unlimited undo
- See a complete material list showing how many of each block your build needs
- Export a high-resolution PNG reference image, a
.mcfunctiondatapack file, or command-block commands
Who we are
MinecraftPixelArt.com is built and maintained by a small independent team of web developers who also play Minecraft. We are not a company with a sales department; we are people who wanted this tool to exist and decided to build it properly. The site is supported by advertising, which is what keeps it free to use with no account, no sign-up and no usage limits.
Our commitments
We keep the tool free. We do not require registration. We do not upload, collect or store the images you convert. We do not sell personal information. When we add a feature, we try to make it work on a mid-range phone and not just a fast desktop, because a large share of our visitors are on mobile.
Get in touch
Feature requests, bug reports and corrections are genuinely welcome — a lot of what the tool does today came from user suggestions. You can reach us through our contact page or by email at support@minecraftpixelart.com.
