What is the difference between .schematic and .schem?

.schematic is the older MCEdit-era format based on numeric block IDs, while .schem is the newer Sponge format based on namespaced block states.

Will every old block convert exactly?

Common blocks convert reliably, but some legacy metadata has no exact modern equivalent. Preview the result before using it in a world.

Why do some blocks look different after converting?

The 1.13 flattening changed how many blocks and their states are defined, so a handful of legacy metadata values have no exact modern match and fall back to the closest block.

Does this need Minecraft 1.12 or older installed?

No. The conversion runs entirely in your browser, so you can upgrade old .schematic files without opening a legacy Minecraft client.

Convert .schematic to .schem

Convert the legacy MCEdit .schematic format used by Minecraft 1.12 and older into the modern .schem format used by current WorldEdit installations.

The .schematic and .schem formats

The legacy .schematic format from the MCEdit era stores blocks as numeric IDs with a separate metadata array, a design from before Minecraft's 1.13 flattening. The modern Sponge .schem format instead lists namespaced block states such as minecraft:oak_stairs[facing=east]. Converting maps each legacy numeric ID and data value to its flattened block state so that current WorldEdit and FAWE installations can read an older schematic library without an old client.

How to convert .schematic to .schem

Upload the legacy .schematic file.

Check the converted palette and orientation in the preview.

Export as .schem for a modern WorldEdit-compatible file.

When to use this conversion

This is designed for bringing older schematic libraries into a current editing workflow without first opening them in an old Minecraft client.

Compatibility notes

Legacy numeric block IDs are mapped to modern block names where possible. Because Minecraft's flattening changed block data substantially, inspect unusual blocks and states in the preview.
