icon modifier
by Reversal
Icon modifier replaces the default Minecraft window icon with a custom image, shown in the taskbar and the title bar.
What it does
Icon modifier changes the icon of the game window. The mod reads a file named logo.png from the .minecraft folder, or from a fallback location inside the mods directory, and the image replaces the vanilla icon. The vanilla icon is cancelled, so only the custom one is shown in the taskbar and the title bar. Fabric API is required.
The image is decoded with STBImage, which Minecraft already bundles through its LWJGL dependencies, so no extra library is added. The decoded picture is passed to GLFW, which sets it as the operating system window icon. To change the icon, a player places logo.png directly in the .minecraft folder and launches the game again.
The mod runs on Fabric for Minecraft 1.21.1 and needs Fabric Loader 0.16.9 or newer. Eleven release versions are published, and the latest Fabric file is 2.1.15 for 1.21.11. It is client-side only, so the server does not need it. The code is released under the MIT License and is open source.
Key features
Custom window icon
A user-supplied image replaces the default Minecraft window icon in the taskbar and the title bar.
Logo file lookup
The game looks for logo.png in the .minecraft folder and falls back to a location inside the mods directory.
GLFW icon setting
The decoded image is passed to GLFW, which applies it as the operating system window icon.
Vanilla icon cancelled
The default Minecraft icon is not shown when the custom one is loaded, so only the chosen image appears.

Use cases
Who it’s for: Players who run the game client on Fabric and want a custom window icon. Server owners do not need the mod, because it changes only the client window.
How it compares
Advanced Tab is client-side only, uses All rights reserved and is published for 1.21.11 only. Custom Window Brand is also client-side only with All rights reserved and covers 1.21.11 alone. NameTag Logo is a client required mod with All rights reserved for 1.21.8 – 1.21.11, so it fits a player who needs that range rather than a single version. Icon modifier is open source under the MIT License and covers a wider span of releases.

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.
