Open FAQ
Free Minecraft tools FAQ
Are these Minecraft resource pack tools free?
Yes, every one of them, with no account to make and no limit on how many packs or textures you run through them.
Are my resource packs uploaded anywhere?
No. Every tool runs in your browser, so your packs and textures never leave your computer.
Which Minecraft versions do the tools work with?
Java Edition resource packs from 1.6.1 to 26.3. The optimizer, texture compressor and merger work on a pack of any version, and the pack.mcmeta generator and pack format table cover every release.
How do I make my resource pack smaller?
Run it through the resource pack optimizer. It recompresses every texture without changing a pixel, minifies the JSON and removes files the game never reads.
