Orbit the whole structure, fly through the inside in first person to check rooms and redstone, or slice it one layer at a time like a blueprint. There is also a walkthrough that places the build block by block, in the order you would actually build it.
Opens .litematic, .schem, .nbt and Bedrock .mcstructure — plus the legacy .schematic that downloads from before Minecraft 1.13 still use, which stores numeric block ids and is translated to modern blocks as it loads.
The materials panel counts every block in the build, sorted by how many you need, so you can gather for a build before placing a single block of it.
Switch on Edit to place, remove and pick blocks straight in the 3D view, or drag out a box and fill, replace, hollow or clear it in one go. Editing works in Layer view too, one slice at a time. Undo is unlimited, and the edited build downloads as .litematic, .schem, .nbt or .mcstructure — the file you opened is never touched.
The file is read and rendered in your browser. There is no upload, no account, and no install — and no size limit beyond what your own machine can hold.
Need the build in a different format? Convert it to Litematica, WorldEdit, a structure block file or Bedrock — also without uploading anything.
