Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.20–1.20.1 · Fabric⬇ Download for 1.19.4 · Fabric⬇ Download for 1.19.3 · Fabric⬇ Download for 1.19–1.19.2 · Fabric⬇ Download for 1.18.2 · Fabric⬇ Download for 1.18.1 · Fabric⬇ Download for 1.19.3 · Forge⬇ Download for 1.19–1.19.2 · Forge⬇ Download for 1.18.2 · Forge
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Hello anyone potentially reading this. Given the very low demand for this mod, I have eventually decided that it is unfortunately no longer worth continuing to maintain this mod. Although disappointing for anyone potentially still using this mod, some of my "top" projects and new mod ideas also already take a lot of time and effort to maintain and work on, meaning it is next to impossible for me to direct my focus on mods that have "low demand". Below I will offer what I believe to be a helpful alternative to anyone needing help reducing their world sizes for latest game versions.

 

PROJECT DESCRIPTION STARTS HERE:

Regarding 1.19.3 and going forward: Many changes were made to the game with the release of 1.19.3, and Mojang has stated that they may bring new features in "patch" (1.x.x) releases now, and not just "minor" (1.x) releases. As such, please avoid using this mod on versions it does not specify it supports, as it could lead to crashes and (possible?) damage to world files (depends on the Minecraft update).

This Minecraft mod reduces world size by discarding unused chunks.

Important: Please back-up your world if you are planning on using this mod on an already existing world. This mod shouldn't cause any issues, but it is still a good idea to back-up worlds, just in case.

 

How to use this mod:

  1. Go to the world selection screen
  2. Select a world of your choice
  3. Click on the "Edit" button
  4. Click on the "Optimize World" button
  5. There should be a checkbox called "Remove uninhabited chunks". Check it it.
  6. Click on "Create backup and Load". This will back-up your world just in case something goes wrong.
  7. That's it. It's best to also verify everything went to plan and that no data loss took place.
