How do I install Enhanced Packet Compression?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

Enhanced Packet Compression

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.

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.

This mod enhances network efficiency by providing control over packet compression levels.

Vanilla Minecraft servers compress packets exceeding a specific size threshold to help conserve bandwidth and improve connectivity for players with slower connections. The 'network-compression-threshold' setting in the 'server.properties' file manages this behavior.

This mod offers further optimization by allowing you to adjust the packet compression level. This capability can potentially reduce CPU load at the very slight cost of some network bandwidth, given everything is configured correctly. Servers with large player counts can particularly benefit from this customization.

While this mod is designed for servers, this mod can technically run client-side, however running it client-sided isn't recommended as this mod does have the slight potential of triggering anti-cheats as this mod does "modify packets" in a way.

That being said this mod can be run completely server-side and vanilla clients can join thanks to how minecraft's network compression works.
