Custom instance Icon

Discord GitHub

Change the minecraft instance icon

What does this mod do?

Custom Logo replaces the default Minecraft window icon — the one shown in your taskbar and title bar — with your own custom image.

No config files. No commands. Just drop a logo.png in your .minecraft folder and launch the game.

How it works

This mod uses a Mixin that intercepts Minecraft's internal Window.setIcon() method before the vanilla icon is applied.

At startup, the mod:

  1. Looks for logo.png in your .minecraft/ directory (or inside mods/ as a fallback)
  2. Decodes the image using STBImage (already bundled with Minecraft via LWJGL — no extra dependencies)
  3. Passes the image to GLFW to set the OS window icon
  4. Cancels the vanilla icon so only your custom one is shown

Installation

  1. Download the .jar and place it in your mods/ folder
  2. Place logo.png directly in your .minecraft/ folder
.minecraft/
├── mods/
│   └── custom-logo-x.x.x.jar
├── logo.png        <- here!
├── saves/
└── options.txt

Tip: You can also place logo.png inside the mods/ folder itself as an alternative.

Image requirements

Property Recommendation
Format PNG with transparency (RGBA)
Size 32×32 or 64×64 px
Name Must be exactly logo.png

Windows uses 16×16 and 32×32 for taskbar icons. A 32×32 or 64×64 image will be scaled automatically.

Requirements

  • Minecraft 1.21.1
  • Fabric Loader 0.16.9+
  • Fabric API
