Chunker vs TrenchBroom

Chunker converts Minecraft worlds between Java Edition and Bedrock Edition, processing worlds locally on the user's machine. It can transfer level settings and world data such as blocks, biomes, and tile entities, as well as multiple dimensions, containers, items, and in-game maps. It can upgrade or downgrade worlds between supported game versions. Inputs include world folders, ZIP archives, and MCWORLD files, with drag-and-drop support. Users can adjust conversion and export settings and save settings for later conversions. The command-line interface supports conversion and workflow integration, but requires Java 17 or higher. Entities and player inventories are not converted; structure data such as villages and strongholds is listed as unsupported or limited. Chunker is free at free and open source under the MIT license. It is available for Windows, macOS, Linux, and through a web interface. Supported versions vary by edition: the listed ranges are Bedrock 1.12.0–1.26.50 and Java 1.8.8–1.21.11 and 26.1–26.3. Check compatibility before converting a world.

TrenchBroom is a free level editor for brush-based engines such as Quake, Quake 2, and Hexen 2. It provides a 3D workspace alongside up to three 2D views. Brush editing includes vertex changes, clipping, scaling, shearing, and constructive solid geometry operations for merging, subtracting, or hollowing shapes. A UV view handles textures and supports multiple material collections. The entity browser accepts drag-and-drop placement and definitions from FGD, ENT, and DEF files, while model display includes mdl, md2, md3, bsp, and dkm formats. An issue browser filters map problems, helps resolve them, and offers automatic quick fixes. TrenchBroom can call external compilers and launch game engines, but those compilation tools are separate. It supports several Quake, Valve, Hexen 2, and package formats. The 2026.2 requirements list Windows 10 1903+, Linux with glibc 2.33+, or macOS 13+, with OpenGL 2.1 and GLSL 1.2 hardware.
