What World Repair Studio is

World Repair Studio is a free desktop editor for Minecraft Java Edition world saves and region files. It helps you inspect terrain, select chunks, move builds between compatible saves, and prepare areas for Minecraft to generate again. An isometric view combines surface colors and terrain heights for reviewing terrain before selection. Its 2D region map supports filters and overlays for age, status, biome, entities, structures, coordinates, and other stored data. World tabs and selection context let you copy and paste selected areas between open Java Edition saves. You can export selected chunks or images before destructive work. Removing selected chunks allows Minecraft to regenerate them, but the software does not automatically diagnose every corrupt save. Inspection, selection, copying, and 3D viewing are non-destructive; deleting, importing, or changing chunk data requires confirmation. Release 1.0.0 is based on MCA Selector 2.8, uses Java 21 with JavaFX, and is distributed under the MIT License.
