BL World Icon Editor
by BattryLeaf
BL World Icon Editor replaces a Minecraft world's icon with a screenshot taken in-game, so a save can show the scene the player chose.
What it does
Players open a world, position the camera where they want the thumbnail shot, and capture it with a hotkey. Pressing F1 hides the HUD first, which keeps the screenshot clean. The captured image is resized and saved in the format Minecraft expects for world icons, so no external editor or manual resizing is needed. The mod works with singleplayer worlds, and it loads a world and lines up the shot instantly.
The mod is a Fabric client mod, so only the client needs it; servers and other players are unaffected. It covers 12 release versions, and the latest Fabric file, 1.0.0, is built for 1.21.11. Fabric API must be installed alongside it. The code is released under the MIT License, but the project is not open source.
Key features
In-game world icon capture
Screenshots taken inside the game become the icon shown for a singleplayer world in the world selection list.
Automatic icon formatting
The captured image is saved in the correct icon format without any manual resizing step.
Hotkey workflow
A single hotkey takes the shot, and F1 hides the HUD so the thumbnail is clean.
Lightweight operation
The mod adds only the capture step and icon saving, so it does little work outside that moment.

Use cases
Labeling a build
A player can frame a finished build or landscape and use that view as the icon, so the save is recognizable in the list.
Showcasing a world
Saves kept for display or streaming can carry a chosen screenshot instead of the default thumbnail.
Who it’s for: Players who keep many singleplayer worlds and want each save to show a recognizable view, without opening an image editor to prepare the icon.
