Frequently Asked Questions
Answers about the generator, the block palette, and getting a finished build to stand up in your world.
Is the Minecraft art generator free?
Yes. Every feature — conversion, the block preview, the PNG download and the command export — is free, with no account and no limit on how many images you convert. The site is paid for by ads.
Do I need to install anything?
No. The whole thing runs in your browser. There is no download, no mod, no launcher change and no Java installation beyond whatever you already use to play.
Are my images uploaded to a server?
No. Conversion happens on your own device using the HTML canvas, so the picture never leaves your computer. That also means the tool works if your connection drops mid-session.
What image formats can I use?
PNG, JPEG, WebP, GIF and BMP all work. PNG with transparency is the best choice, because transparent areas are skipped instead of being filled with a background colour.
What does tile size actually change?
It sets how many image pixels collapse into a single Minecraft block. A tile size of 4 turns every 4×4 patch of the image into one block. Smaller values give more detail and many more blocks; larger values give a chunkier build you can finish in an evening.
How many blocks will my art need?
Divide the image width by the tile size, do the same for the height, and multiply. A 1000×1000 image at tile size 4 is 250×250, which is 62,500 blocks. At tile size 20 the same image is 2,500 blocks.
Does it work for Java and Bedrock?
The image export works for both. The generated commands use standard syntax that runs on Java Edition as written; on Bedrock you can drop the minecraft: prefix and use a behaviour pack function instead of a datapack.
How do I run the commands without spamming chat?
Save them as a .mcfunction file in a datapack and run it with /function, or paste them into a chain of command blocks. The tutorial walks through both.
Why does my photo look blotchy?
There are no in-between shades in the palette, so smooth gradients break into bands. Increase the contrast and saturation of the source image before uploading, crop tighter to the subject, and expect a poster-like result rather than a photograph.
Can I choose which blocks it uses?
The generator matches against a broad palette automatically. If you want to restrict the build to one family, convert as normal and then swap colours in game with /fill … replace, or use the editor to repaint areas with a chosen block.
Which blocks should I avoid?
Anything that falls (sand, gravel, concrete powder), anything flammable near lava or portals (wool, planks), and blocks with side effects such as redstone blocks, slime and glowstone. The block list page marks the practical alternatives.
Can I use this on a multiplayer server?
You can build the art anywhere, but most servers restrict /fill and command blocks. Build it in a single-player world and copy it over with a structure block, or ask an admin to run the function.
Is there a limit on image size?
Very large images (above roughly 4000 pixels on a side) will slow your browser down during conversion. Resize to around 1000–2000 pixels first; you lose nothing, because the tile size throws that detail away anyway.
Can I sell or publish builds made with this?
The tool puts no restriction on what you do with the output. The artwork you feed into it is a different matter — a company logo or a game character stays under its owner's copyright, so keep those to your own world.
Is this made by Mojang?
No. MinecraftArt.com is an independent fan tool. It is not an official Minecraft product and is not approved by or associated with Mojang or Microsoft.
Still stuck?
If your question is about a specific image or a command that will not run, send the details — the image dimensions, the tile size you used, and what happened. Answers usually come back within a couple of days.
