Schematicraft vs SchemConvert

Schematicraft is a schematic library and converter for sharing Minecraft builds across formats, with support for Hytale Prefab files as well. Its browser converter handles Litematica, WorldEdit/Sponge, legacy MCEdit, Structure Block/Create, Building Gadgets, Bedrock Structure, and Hytale Prefab, and lists 42 conversions. Before downloading, users can see which data will carry over or be dropped; formats that record a Minecraft version allow a version choice. Cross-edition and cross-game conversions translate block names, and some other data may not transfer. The public library has searchable builds, filters, and curated collections. Schematic pages show block counts, unique block types, dimensions, and material lists. Without an account, the converter accepts files up to 8 MB. Schematicraft says it does not keep uploaded files but records encountered formats, blocks, and versions to improve conversions. An official alpha mod adds in-game library access and integration with Create and Building Gadgets 2. Developers can use an API for search, library access, uploads, downloads, and conversion; API endpoints are rate limited.

SchemConvert is a free, open-source desktop tool for converting Minecraft schematic files between four formats: .nbt, .schem, .litematic, and .bp. The formats correspond to different Minecraft tools and workflows: .nbt is used by vanilla structure blocks, .schem by community programs such as WorldEdit and MCEdit, .litematic by Litematica, and .bp by Axiom for blueprints. It can process multiple schematics in one batch, and command-line conversion to .litematic is supported. The listed placement workflow is export-only, so the tool’s role is converting and exporting files rather than placing them. SchemConvert runs on Linux, macOS, and Windows desktop systems and requires Java 21 or later. The repository is published under the GPL-3.0 license. GitHub reports no published security advisories and no SECURITY.md file. The project is hosted on GitHub, where its owner describes occasional coding and contributions to ParchmentMC mappings.
