MOSSBACK STUDIO

pack.png maker for Minecraft packs

Drop any picture. You get the pack.png that shows next to your resource pack or data pack in the game's list, or the icon.png of a world. Nothing is uploaded.

Where the file goes

• Resource pack or data pack: pack.png at the top of the pack, next to pack.mcmeta. Not inside assets or data. In a zip it must be at the top of the zip, not inside a folder.
• World: icon.png in the world's folder, next to level.dat. The game makes one by itself the first time the world is played; yours replaces it.
• Do not rename the file. The name is all lower case.

If the icon does not show

• Type: it has to be a real PNG. A JPG renamed to .png shows the grey default icon.
• Shape: the game draws the icon as a square, so a picture that is not square gets squashed. This page always writes a square.
• Place: a pack that was zipped with its folder inside has pack.png and pack.mcmeta one level too deep, and the game does not see the pack at all. The resource pack check tells you when that is the case.
• Old picture stays: leave the pack screen and open it again, or press F3+T. For a world, go back to the title screen.

Which size to pick

The list shows the icon small, so 128 by 128 is plenty and the usual choice. 64 is enough for pixel art. Bigger files only make the pack heavier. A world icon is always 64 by 64. Need the other file too? The pack.mcmeta generator writes it for any version.
