How to Edit the Blocks in a Minecraft Texture Pack

By Brandon Dingess

"Minecraft" is a block-based computer game that allows players to construct massive and detailed buildings while collecting resources for survival and fighting off monsters. The game is supported by many third-party texture packs that serve to change the default look of the game into something more visually interesting. Sometimes, though, it's necessary to tweak these texture packs either for aesthetic or thematic desires. The look of all the game's blocks can be changed by manipulating the "terrain.png" file.

Things You'll Need

  • Decompression program such as Stuffit, Archive Utility or WinZip.
  • Graphics-editing program such as MS Paint, Adobe Photoshop or Paint.NET

Step 1

Download and install "Archive Utility" or any other program capable of decompressing ".jar" files. Any program designed for .zip files will work with .jar files.

Step 2

Locate the "minecraft.jar" file. On Macs, it's located in your home directory in "Library/Application Support/minecraft/bin". For Windows machines, it's located under "My Computer\Users\"Your user name"\AppData[hidden]\Roaming\.minecraft".

Step 3

Right click on "minecraft.jar" and select "Open With > Archive Utility." This will decompress the .jar file and create a folder called "minecraft" within the "bin" folder.

Step 4

Open the new minecraft folder and locate "terrain.png." This file controls the look of the different blocks in the game.

Step 5

Open "terrain.png" in your image editor of choice and make changes to whichever blocks you desire.

Step 6

Save your changes and close the image editor.

Step 7

Right click on the minecraft folder containing "terrain.png" and select the option "Compress 'minecraft'." This will create a file in the /bin directory called ""

Step 8

Rename "" to minecraft.jar. Your changes to the block designs should appear the next time you load the game.

Tips & Warnings

  • Always make a backup of your .jar file before you decompress it and edit its contents. If you forget to do this you can force your Minecraft client to download a fresh .jar file by clicking "Options" on the splash screen and selecting "Force update."
