Drop your .schematic file below. The converted .aschem file will download automatically.

How it works
1
Select your file. Drop any standard .schematic file — exported from WorldEdit, Schematica, or any compatible tool.
2
Instant conversion. The file is decompressed and parsed right here in your browser. Block IDs and metadata are bit-packed into Astra's format.
3
Download and import. The .aschem file downloads automatically. Import it in-game via the Schematics menu.
Good to know
100% offline
Your schematic files never leave your device. All processing runs locally in JavaScript — no servers, no uploads.
Astra .aschem format
The .aschem format is custom-built for Astra Client 2. It packs block ID and metadata into a single integer per block for efficient in-browser handling.
Using the converted file
Once you have your
.aschem, open the in-game Schematics menu and press
Import. See the
full guide in the docs.
