What it is

SchemConvert is an open-source Java utility that moves Minecraft schematic files among .nbt, .schem, .litematic, and .bp formats. Linux, macOS, and Windows are supported, provided Java 21 or newer is installed. A simple JAR-based GUI handles one-off jobs, while the command line accepts an input file and optional output format.

  • WorldEdit Version tag may be missing after some conversions
  • Reported .litematic conversion error despite Java 21

Who it suits

Players exchanging builds between current Minecraft schematic tools Groups that need GUI or command-line conversion Desktop users comfortable installing Java 21 or newer

Choose SchemConvert when your group needs a free way to move builds among vanilla structure files, WorldEdit-style schematics, Litematica, and Axiom blueprints. It works across the three major desktop platforms and provides both a GUI and command-line conversion paths. Before relying on it for a shared library, check the output in your target tool: legacy .schematic support is absent, WorldEdit metadata has been an issue, and some Litematic conversions have failed. Java 21 or newer is part of the setup.

Questions

Which Minecraft formats can SchemConvert handle?
The utility works with .nbt, .schem, .litematic, and .bp files.
Which systems can run SchemConvert?
Linux, macOS, and Windows are supported when Java 21 or later is installed.
Can it convert several schematics at once?
Yes. Batch conversion is supported. A folder-based recursive batch workflow is still an open request.
Does it have a graphical interface?
Yes. Download the JAR, select the input and output files, then press Convert.
How does the command line choose an output format?
The CLI takes an input file and may receive an output format. If none is supplied, it derives the format from the output filename; supplying only a format places the result beside the input.
Does it support the old .schematic format?
The application has no .schematic format selector. The maintainer describes that format as old and low priority.
What should I know about WorldEdit compatibility?
One reported .nbt-to-.schem conversion was missing the Version tag required by WorldEdit 7.2.16, so inspect converted files before sharing them.
