Convert your worlds between editions/versions.
The Universal Minecraft Tool's Converter is the first ever to support conversion options like mixed output chunk versioning and depth fixing which are crucial to getting correct terrain regeneration after the 1.18 world height update.
The highly-requested feature, output version targetting, is finally here! Specify which version the output world should be and the Converter will make all the necessary decisions to best optimize the world for that target version.
The Universal Minecraft Tool spares no expense when it comes to output world accuracy. During conversion, an internal layer uses a pseudo 'universal format' for entity, tile entity, and item conversion. A sophisticated database was manually populated to deal with the unique undocumented edge cases brought about by snapshot and beta updates to ensure unrivaled accuracy.
In 2020, the Universal Minecraft Converter was the first software to solve a conversion issue introduced in the Java Aquatic update, persistent block property storage. Block properties needed to be recalculated during conversion which was no easy task because each block's properties were dependent on the blocks around it, even across chunks.
Recently, the problem has returned and now affects Bedrock edition. Thankfully, the Universal Minecraft Tool's Converter has completely revamped block property recalculation to be faster, more accurate, and supports both Java and Bedrock editions!
The Converter will efficiently recalculate lighting and heightmap information if the output world version requires it. This is very important because an input world may not have any lighting or heightmap information stored whatsoever. Missing lighting will cause very bad performance and a completely dark world while missing heightmap information can break beacons, lighting, map items, and more.

The Universal Minecraft Tool takes full advantage of your CPU's multiple cores by intelligently assigning certain tasks to run in parallel. This enables incredibly fast conversions for high core count CPUs.
This is more than just running the same step across multiple cores, however. The Converter will run completely different steps at just the right times to speed up block property and lighting recalculations (which were formerly single-threaded operations).
There are so many more amazing features still in development that will expand the capabilities of the Converter. Keep an eye out for these additions, you won't be disappointed!
