Frequently Asked Questions
Which 3D file formats can I convert?
You can load STL, OBJ, PLY, GLB, glTF, 3MF, FBX, and COLLADA (DAE) files, and export to GLB, glTF, STL, OBJ, or PLY. Just pick your source format and target format from the dropdowns.
Is my 3D model uploaded to a server?
No. Conversion runs entirely in your browser using WebGL and JavaScript. Your model file never leaves your device, which keeps your designs completely private.
Why does my converted STL or OBJ lose colors and textures?
STL, OBJ, and PLY store geometry only, so materials and textures are not preserved. To keep materials, convert to GLB or glTF, which support embedded materials.
What is the difference between GLB and glTF?
They are the same format — glTF is a JSON file (often with separate assets), while GLB packs everything into a single binary file. GLB is the most convenient for sharing and web use.
