Question 1

Which schematic formats can I convert between?

Accepted Answer

You can open .litematic (Litematica), .schem (WorldEdit / Sponge), .nbt (structure block), .mcstructure (Bedrock) and the legacy pre-1.13 .schematic, and write out .litematic, .schem, .nbt or .mcstructure.

Question 2

Can I open an old .schematic file?

Accepted Answer

Yes. Files saved before Minecraft 1.13 store numeric block ids rather than names, and they are read here and translated to modern blocks, so an old download can be converted to Litematica or WorldEdit and used in a current world.

Question 3

Are my files uploaded anywhere?

Accepted Answer

No. The conversion runs entirely in your browser. The file is read on your own device and the converted copy is written there too.

Question 4

Why will my converted file not open in Litematica or WorldEdit?

Accepted Answer

Both refuse a schematic that claims a Minecraft version newer than the one reading it. Set the Minecraft version control to the version you actually play and convert again.

Question 5

How good is the Java to Bedrock conversion?

Accepted Answer

Blocks and their positions carry over, and stairs, logs and slabs keep their orientation. Other rotations fall back to a default, container contents are not carried across, and any block with no Bedrock equivalent will be missing. Preview the result before you build on it.

Question 6

Why is the structure block option sometimes unavailable?

Accepted Answer

A vanilla structure block cannot load anything larger than 48 blocks on any axis, so the .nbt option is switched off for builds above that rather than handing you a file the game will refuse.
