Custom 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:

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

Installation

Download the .jar and place it in your mods/ folder
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+
