Schemalook vs SchemConvert

Schemalook is a free web-based Minecraft schematic viewer and toolkit. Its viewer opens.litematic,.schem,.schematic, and.nbt files in 3D, with orbiting, zooming, shadow and day/night controls, and layer-by-layer inspection. It counts required blocks and links each block to a wiki page containing recipes and stats. Files remain on the device unless saved to a Schemalook library. Saved builds can be private, shared by link, or limited to specific people, with download controls. The pixel-art tool converts PNG, JPG, and WebP images into block schematics, accepting files up to 10 MB and 4096 pixels per side. A map-art tool supports layouts up to 4×4 maps. Palette generation suggests block combinations by texture colour and permits palettes of three to eight blocks. The converter exports litematic, schem, nbt, and Bedrock mcstructure formats and warns about replacements for older game versions. The free viewer upload limit is 7 MB, and the workflow is export-only.

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.
