Which Minecraft schematic formats can the viewer open?

The viewer opens .litematic (Litematica), .schem (WorldEdit / Sponge), .schematic (legacy MCEdit), .nbt (Java structure blocks), .bp (Axiom blueprints), and .mcstructure (Bedrock structure blocks).

Can I view Bedrock .mcstructure files?

Yes. Drop a Bedrock .mcstructure structure-block export (or a zipped one) onto the viewer and it renders in 3D just like a Java schematic, with the same layer-by-layer guide, materials list, and export options.

Do I need to install anything?

No. The viewer runs entirely in your browser — no download, no extension, no Minecraft install required.

Are my schematic files uploaded to a server?

No. Files are read and rendered locally in your browser. Nothing is uploaded to Bloxelizer's servers.

Can I view schematics that use modded blocks?

Yes. Import the mod .jar in the Mods panel and the viewer will render its blocks with their real textures alongside vanilla blocks.

Can I open a schematic from a URL?

Yes. Use the URL field in the sidebar, or open the page with a ?url=… query parameter pointing at the file.

Is the schematic viewer free?

Yes. The Bloxelizer schematic viewer is a free web tool with no account required.

Can I convert the schematic to another format after viewing it?

Yes. Use Bloxelizer's Converter to convert between .litematic, .schem, .nbt, .bp, and .mcstructure with the same browser-based engine.

What's the difference between .litematic and .schem?

.litematic is the format used by the Litematica mod for schematic overlays and pixel-perfect building guides. .schem is the newer Sponge/WorldEdit format used by servers and plugins. Both store block data and NBT, but .litematic supports multiple regions and per-block metadata that .schem does not. Bloxelizer converts freely between them.

Does the viewer work on mobile?

Yes. The viewer runs on mobile browsers with a touch-optimized layout — drop or paste a file, pinch to zoom, and swipe to orbit. WebGL2 is required, so any modern iOS Safari or Android Chrome build works.

How large a schematic can I open?

The viewer handles builds up to several million blocks. Very large builds automatically switch to optimized rendering so layer-by-layer scrubbing stays responsive.

Can I share a link that opens my build for someone else?

Yes. Upload the schematic somewhere it's publicly reachable and share https://bloxelizer.com/viewer?url= . The viewer fetches the file and renders it locally — nothing hits Bloxelizer's servers.

Drop your schematics anywhere

Preview them in 3D, follow them layer by layer, or convert to another format. Bring in several and they land in one scene. Everything runs on your machine, nothing is uploaded.
