WorldEditSchematic Viewer

Open WorldEdit .schem schematic files in your browser. Inspect any region exported from WorldEdit or FastAsyncWorldEdit in 3D. No install, no server, no upload.

What is a .schem file?

.schem is the schematic format used by WorldEdit, the most widely deployed building tool on Minecraft servers, and by its forks like FastAsyncWorldEdit. A .schem is essentially a region snapshot: block ids, blockstates, biomes, and a bounding box, all stored as compressed NBT.

Why view .schem files outside WorldEdit?

WorldEdit ships with //paste and //schem load for pulling schematics into a world, but there's no built-in preview. To see what's inside a file before pasting it, players historically had to spin up a fresh creative world or rely on clunky third-party tools.

Shulkr opens .schem files directly in the browser. No install, no account, and the file never leaves your device. Useful for auditing community schematic packs, comparing variants, or figuring out what an unlabeled download contains before pasting it into a live server.

Shulkr supports the modern Sponge .schem format used by WorldEdit, FastAsyncWorldEdit, and similar tools. Files saved in the legacy pre-1.13 .schematic format need to be re-saved as .schem in WorldEdit first.

FAQ

Frequently asked questions

How do I open a .schem file?

Open the Shulkr viewer and drag the .schem file anywhere on the page (or click Open a schematic). Shulkr parses the WorldEdit format directly. No in-game paste, no server, no conversion needed.

What is a .schem file?

.schem is the modern Sponge schematic format used by WorldEdit and its forks (FastAsyncWorldEdit, AsyncWorldEdit). It stores blocks, blockstates, biomes, and a bounding box in a compressed NBT file. It replaced the older .schematic format around Minecraft 1.13.

Does this work with FastAsyncWorldEdit (FAWE) schematics?

Yes. FastAsyncWorldEdit produces standard Sponge .schem files, which Shulkr opens without any extra steps. The same applies to AsyncWorldEdit and other WorldEdit forks that follow the .schem format.

Can I preview a server schematic before pasting it?

Yes. Drop the .schem into the Shulkr viewer to see exactly what's in it before running //paste on your server. Useful for auditing community schematic packs, comparing variants, or inspecting an unlabeled download.

What if I have the older .schematic format?

Shulkr currently supports the modern .schem (Sponge) format, .litematic, .nbt, and .mcstructure. The legacy .schematic format used before Minecraft 1.13 is not supported. Re-save it from WorldEdit as .schem to open it.

Are my files uploaded to a server?

No. Everything runs entirely in your browser using WebGL and JavaScript. Your schematic files never leave your device.

Can I link directly to a schematic URL?

Yes. Add a url query parameter containing a direct link to a supported schematic file.*/viewer?url=https://www.example.com/schematic.litematic*The linked file must end in .schem, .litematic, .nbt, or .mcstructure, stay under the remote import size limit, and be publicly reachable. shulkr validates the URL before fetching it, so use public schematic links only.
