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.

STL → GLB
Local only

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.

GLB → STL
Local only

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.

OBJ → GLB
Local only

FBX to GLB Converter

Converts Autodesk FBX files, animation included, into GLB for three.js scenes, Unity and Godot projects, and AR pipelines.

FBX → GLB
Local only

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.

GLB → USDZ
Local only

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.

Optimize GLB / USDZ
Local only

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.

GLB → OBJ
Local only

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.

STL → OBJ
Local only

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.
