About this Mod
ResourcePackExtractor
ResourcePackExtractor (or Resource Pack Extractor) is a Fabric mod for Minecraft 1.21.11 that allows you to extract server resource packs directly from within the game.
What it does
- Lets you save and extract any resource pack a server sends you.
- Works even with corrupted or protected packs, which are often used by servers to prevent unpacking.
- Adds an easy-to-use button in the resource pack selection screen for quick extraction.
- Provides direct access to the extracted folder from within Minecraft.
Why you should use it
- No need for external tools, everything happens inside Minecraft.
- Useful for learning, customizing, or analyzing how servers design their packs.
- Bypasses broken or obfuscated resource packs that normally can’t be opened, while still keeping them usable.
Important Information ⚠️
While this mod enables the extraction of protected or corrupted resource packs, the extracted content may still be subject to copyright.
