In their own words
Chunker
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.
UAssetGUI
UAssetGUI is a desktop tool for examining and modifying Unreal Engine game assets by hand. It supports .uasset, .umap, .usmap, .utoc and .ucas files, as well as JSON. Windows is supported directly; Linux setup runs the Windows executable through Wine. Command-line arguments can export and import UAssetAPI JSON without opening the graphical interface, and custom C# scripts can extend the program. Portable mode, available in v1.1.0 or later, keeps configuration and saved mappings in a Data folder beside the executable. The v1.1.0 release added opening and saving .utoc and .ucas containers through built-in retoc integration. Pre-built binaries and an experimental build are available from the repository’s Releases page. Release notes report support for Unreal Engine 5.6 and 5.7, while earlier notes identify limits for some Unreal Engine asset support. UAssetGUI is free under the MIT License, which provides the software without warranty. The maintainer announced retirement from UAssetGUI development, though future contributors or releases might follow.
