BuildSchematics Converter vs Schemalook

BuildSchematics Converter changes Minecraft schematic files between supported formats in a web browser. It accepts.litematic,.schem,.nbt,.mcstructure, and older pre-1.13.schematic files, and exports.litematic,.schem,.nbt, or.mcstructure. Legacy numeric block IDs are translated into modern blocks. Conversion happens in the browser, with files read from and written to the device; the maker says browsing, previewing, and downloading need no account. A 3D preview is available, but the workflow is export-only. In Java-to-Bedrock conversions, blocks and positions carry over, and stairs, logs, and slabs keep their orientation. Other rotations use defaults, container contents do not transfer, and blocks without Bedrock equivalents are omitted. The.nbt option is disabled for builds over 48 blocks on any axis. If Litematica or WorldEdit rejects a converted file as too new, the page advises selecting the Minecraft version being played. The free plan is free.

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.
