Compact
Managing massive quantities of cobblestone, dirt, or netherrack has always been a headache in Minecraft. The Compact mod solves this elegantly by introducing a dynamic compression system that works with virtually any block in the game. Unlike traditional compression mods that hardcode a few block types, Compact gives you total control over which blocks can be compressed and how many times, all through a simple configuration file. Whether you're running a skyblock world, an industrial modpack, or just want to tidy up your chest monster, Compact for Minecraft is the ultimate storage optimization tool.
What Makes Compact Different?
Most compressed block mods come with a fixed list of supported materials and a rigid compression limit. Compact breaks those boundaries. You can add any block from vanilla Minecraft or from your favorite mods to the compression list. The mod then automatically generates unique registry names like compressed:cobblestone_1x, compressed:dirt_4x, and so on. Because each compressed variant is a distinct block with its own registry entry, there are no tile entities involved. This means zero overhead from ticking block entities and full compatibility with mods like Project E that rely on standard block IDs rather than NBT data.
Key Features of Compact
Fully Configurable Compression
You decide which blocks become compressible. The default configuration includes cobblestone, dirt, netherrack, sand, and gravel, but you can add any block from any mod by specifying its registry name. The maximum compression level is also adjustable per block, from 1x up to 32x. Be mindful, though: each compression level creates a new block, so setting extremely high values can impact performance. The mod is designed to be lightweight, using a single 16x16 texture and tinting it via IBlockColor to represent different compression tiers, avoiding texture atlas bloat.
Automatic Resource Pack Generation
Once you edit the config, Compact automatically generates a resource pack that provides models and textures for every compressed block. There is no need to manually create assets or worry about missing textures. The mod reuses existing block textures from the game, so everything looks consistent. This approach keeps RAM usage low and prevents the dreaded TextureStitchException that can occur when too many custom textures are loaded.
Seamless Modpack Integration
Because compressed blocks use standard registry names, they work flawlessly with storage systems, autocrafting, and recipe mods. You can use them in any crafting recipe without complex NBT tags. This makes Compact an ideal choice for modpack creators who want to add deep storage options without breaking other mods. The mod is available for Minecraft versions 1.16.5, 1.18.2, 1.19.2, and 1.20.1 on the Forge loader, ensuring broad compatibility with most modern modpacks.
How to Install Compact
Installing Compact is straightforward. First, ensure you have the correct version of Forge installed for your Minecraft version. Then, simply place the Compact mod jar file into your mods folder. If you're using the foxygame.net launcher, you can install Compact directly from its add-on catalog with one click, and the launcher will handle version compatibility and automatic updates for you. After launching the game, the mod will generate a default configuration file in the config folder. You can edit this file to add or remove compressible blocks and adjust compression limits. The changes take effect the next time you start the game, and the resource pack will be rebuilt automatically.
Configuring Your Compressed Blocks
The configuration is a simple JSON file. Here's an example snippet that adds compressed cobblestone and dirt:
{
"compressible": [
{
"registry_name": "minecraft:cobblestone",
"texture": "block/cobblestone",
"max_compression": 32
},
{
"registry_name": "minecraft:dirt",
"texture": "block/dirt",
"max_compression": 16
}
],
"loaded_blocks": -1
}
You can add any block from any mod by using its registry name. The loaded_blocks value controls how many compressed blocks are pre-loaded; -1 loads all. After editing, restart the game and the new compressed blocks will be available. Crafting recipes follow the standard 3x3 compression and decompression pattern, so nine compressed cobblestone of one tier craft into one of the next tier, and vice versa.
Performance and Practical Limits
While the mod can theoretically handle up to 2 billion compression levels, that would crash any game. The default maximum of 32 is already more than enough for most players. Each compression level adds a new block to the registry, so adding hundreds of compressible blocks with high max levels can increase memory usage and world load times. The mod is optimized to avoid texture atlas bloat and tile entity overhead, but it's wise to only configure blocks you actually intend to use. For typical play, compressing cobblestone, dirt, sand, gravel, and netherrack up to 8x or 16x is more than sufficient.
Why Choose Compact Over Other Compression Mods?
Many compression mods hardcode their block lists, making them incompatible with modded blocks. Others use NBT-based systems that break with autocrafting or EMC value calculations. Compact solves both problems by using unique registry names and no tile entities. It's also highly configurable, so you can tailor it to any modpack. The mod is actively maintained and works on recent Minecraft versions, making it a reliable choice for long-term worlds.
