3D model conversion tools
Convert between STL, GLB, OBJ, FBX and USDZ, and optimise meshes before shipping them to a viewer or a printer. Useful when a slicer wants STL, a web viewer wants GLB, and an AR preview on iOS wants USDZ. Conversion happens locally in your browser.

STL to GLB Converter
Converts STL 3D models to GLB (glTF binary) entirely in your browser, no upload or account needed, ready for web viewers, Unity, or Godot.
GLB to STL Converter
Pulls mesh geometry out of GLB or glTF files and exports clean, printable STL, handy for slicing software and 3D printers.
OBJ to GLB Converter
Turns Wavefront OBJ meshes into GLB (glTF binary), the format most web viewers, Unity, Godot, and AR tools expect by default.
FBX to GLB Converter
Converts Autodesk FBX files, animation included, into GLB for three.js scenes, Unity and Godot projects, and AR pipelines.
USDZ Converter
Converts 3D models to USDZ so they open directly in AR Quick Look on iPhone and iPad, no separate app install needed to view them.
3D Web & AR Optimizer
Reduces polygon count and texture size on 3D models, exports the result as GLB or USDZ, and generates ready-to-paste viewer embed code.
GLB to OBJ Converter
Extracts mesh geometry from GLB or glTF files and exports it as Wavefront OBJ for editing in older desktop 3D modeling tools.
STL to OBJ Converter
Converts STL mesh files to Wavefront OBJ format, useful when an older modeling tool or export pipeline expects OBJ instead of STL.
3D Model Viewer
Loads GLB, glTF, OBJ, or STL files for a quick preview right in your browser; drag to orbit the model, scroll to zoom in.
