What Is ObjToSchematic and What Does It Do?

Updated

ObjToSchematic is a tool that converts 3D models into Minecraft blocks. You can upload a model such as .OBJ or .GLB (or a .PNG/.JPG image) and turn it into a build you can paste into a world. It runs in two ways: directly in your browser, or through a Minecraft mod for Java Edition. The site states that the browser version requires no account or payment, and that AI generation from an image or text prompt is free and uses 20 credits per generation.

What it converts and where the output goes

The tool's stated purpose is to take 3D models and produce Minecraft Java and Bedrock formats such as .litematic, .schem, and .mcstructure. The feature list also mentions compatibility with tools like MCEdit, Litematica, FAWE, Axiom, and Blender, so the output can feed into existing building workflows rather than only into the game itself.

Input Output / destination
.OBJ, .GLB 3D models Java and Bedrock schematic formats (.litematic, .schem, .mcstructure)
.PNG, .JPG images (via AI generation) A generated 3D model, then converted to blocks
Text prompt (via AI generation) A generated 3D model, then converted to blocks

The two ways to use it

In the browser

Upload a model or generate one with AI, then convert and download the result. The site describes this path as running in your browser with no account or payment needed. This is the lower-friction option if you just want a schematic file to import elsewhere.

As a Minecraft mod (Java Edition)

The site lists these steps:

  1. Install the mod — download it from CurseForge and place it in your .minecraft/mods folder.
  2. Import a model into your world — open the mod menu with the P key and upload a 3D model or generate one from a prompt.
  3. Position, rotate, and scale — enter Edit Mode with the G key to move, rotate, and scale the object.
  4. Customise in the settings menu — open the mod menu again with P to adjust the available settings.
  5. Paste into your world — click the paste button, or build in survival using ghost blocks and the slice viewer.

The mod is listed as supporting versions 26.1 and 26.2.

Features that affect the result

  • Palette control — you choose which blocks are included or excluded from the build, which is the main lever for matching a style or a survival-legal block set.
  • Ghost preview — translucent blocks let you build in survival, and block picking is supported.
  • Slice viewer — builds can be sliced down to one layer at a time, useful for large or complex models.
  • Customisable pipeline — the site says every stage of the conversion exposes settings you can tweak.
  • Speed — the browser version runs on WASM and the mod uses multithreaded Java.

When to choose which

Use the browser if you want a schematic file quickly and don't need to place it in-game through a mod. Use the mod if you're on Java Edition and want to position, rotate, and scale the build inside your world before pasting, including in survival with ghost blocks.

The site reports 9,609 models converted and describes the tool as "trusted by builders," but those figures are the site's own counters and shouldn't be read as independent validation. For setup details beyond the steps above, the site points to its wiki and a Discord community (listed at 1,187 members, 243 online at the time of the page).
