How to open a .litematic file
- 1
Find the file
Litematica saves schematics in the schematics folder of your Minecraft instance (for example .minecraft/schematics). Downloads from build sites are often .litematic too.
- 2
Drop it here
Drag the .litematic onto the viewer or tap to choose it. It is read inside your browser, so there is no upload and no waiting in a queue.
- 3
Look around
Drag to orbit, scroll or pinch to zoom. Use the layer slider to see the build grow from the ground up, or show a single layer to copy it block by block.
- 4
Take what you need
Download the material list as CSV for your survival build, a PNG snapshot to share, or the whole build as GLB or OBJ for Blender and other 3D apps.
Private by design. The schematic is unpacked and drawn by JavaScript running on your own device. It is never uploaded to a server, so private builds and unreleased maps stay private, and the viewer keeps working on a slow connection once the page has loaded.
What is a .litematic file?
.litematicLitematica schematic- The save format of the Litematica mod (Fabric and Forge). A gzip-compressed NBT file holding one or more named regions. Each region has a position, a size, a block-state palette and the blocks packed as bits inside 64-bit numbers.
RegionsSeveral boxes in one file- A schematic can hold several selection boxes, for example a house and a separate farm. The viewer places every region at its saved offset, including boxes saved with a negative size, so the whole build lines up the way it does in game.
PaletteBlock states- Each region lists the block states it uses, such as minecraft:oak_stairs[facing=north]. The material list groups them by block, so stairs facing different ways count as one line.
.schem / .schematic / .nbtAlso accepted- WorldEdit .schem, old MCEdit .schematic and vanilla structure block .nbt files open here too. For those, the Schematic Viewer page explains the differences.
Why open a litematic outside Minecraft?
Litematica is the most popular way to share builds on Java Edition, but checking a download normally means starting the game, loading a world, placing the schematic and walking around it. That takes minutes, and on a phone or a school laptop it is not possible at all. A browser viewer answers the simple questions in seconds: what does it look like, how big is it, and what will it cost to build.
Size matters before you commit to a project. The viewer reads the enclosing box of all regions and shows it as width x height x length in blocks, so you know whether a build fits your plot, your render distance or a server's height limit. The shown block and face counts also tell you how heavy the build will be for a weaker PC.
Planning a survival build with the material list
The material list counts every non-air block in the view and sorts it from most to least used. Counts of 64 or more are also shown in stacks, which is how you will gather them in survival. Air, cave air, structure voids and similar helper blocks are left out, because you never place them.
The list follows the layer slider. Set it to layer 10 and you get only what layers 1 to 10 need, which is handy when you build in stages or share the work with friends. Switch to a single layer to see exactly which blocks go on that row. The CSV opens in Excel, Google Sheets or Numbers, so you can tick items off as you collect them.
About the colours you see
This viewer does not use Minecraft's textures. Each block is drawn in a flat colour from our own palette, chosen to look close to the block in game: oak planks are warm tan, deepslate is near black, and all sixteen dye colours of wool, concrete and glass have their own shade. Glass, ice and leaves are drawn see-through so you can look inside.
Slabs, carpets, snow layers, torches, flowers, fences and walls get simpler shapes than the real models, so a staircase reads as a staircase-coloured cube and a torch is a thin post. That keeps very large builds smooth on phones, and it is enough to read the layout and count blocks. If you need exact textures, the GLB or OBJ export keeps one material per block type, so you can assign your own resource pack textures in Blender.
What this litematic viewer does
Multi-region files
Every region in the .litematic is placed at its saved position, including regions saved with a negative size.
Layer slicer
Show layers 1 to N, or only one layer, with a slider and one-step buttons.
Material list in stacks
Block counts sorted by use, shown in stacks of 64, downloadable as CSV.
GLB and OBJ export
One mesh and one material per block type, 1 unit = 1 block, ready for Blender.
Big builds stay smooth
Hidden faces between solid blocks are removed, so only the surface is drawn.
Private and free
Runs fully in your browser. No account, no upload, no watermark.
Limits, honestly
- Blocks are flat colours from our own palette, not Minecraft textures, and complex block models (stairs, doors, beds) are simplified to boxes.
- Entities and block entity contents (chest items, sign text, banners, item frames) are not shown.
- Builds with more than about 6 million visible faces are shown a few layers at a time; use the slider to move through them.
- Files up to 200 MB and up to 64 million blocks in the enclosing box can be opened; very large files need a desktop browser with enough memory.
- Bedrock Edition .mcstructure files are not supported yet.
