Ultimate Compression

Compress almost every vanilla block and item — 9 in, 1 out.
Available for Fabric • NeoForge • Forge

Tired of chest monsters and overflowing storage rooms? Ultimate Compression shrinks your stockpiles by letting you compress nearly all vanilla Minecraft blocks and items into dense, space-saving variants. Nine blocks go in, one compressed block comes out — and every recipe is fully reversible, so your resources are never locked away.

Compression isn't just for storage, either. Compressed ingots and ores can be forged into upgraded tools and armor with increased durability and special effects, all the way up to the mighty Ultimate Compressed tier.

• Compressed blocks & items — compact variants of nearly all vanilla blocks, including Grass Blocks, Coarse Dirt, Podzol, Dripstone, Ancient Debris, Sponges, Bricks, Purpur, Ice, Prismarine… and many more.
• Compressed gear — tools and armor crafted from compressed ingots and ores, with boosted durability and unique effects.
• The Ultimate tier — hunt down Ultimate Compressed Ore to craft the most powerful armor set and tools in the mod.
• Fully reversible — decompress anything back into its original blocks whenever you need it.
• Storage-friendly by design — perfect for survival worlds, skyblock grinds, and storage-hungry modpacks.
