When you need this
The most common path in 2026: an AI generator (Meshy, Tripo, Hunyuan) gives you a .glb, but your slicer — Bambu Studio, PrusaSlicer, Cura — wants .stl. Drop the GLB above and the STL will land in your slicer, geometry intact.
GLB to STL — FAQ
Does the STL keep my model’s colors?
No — STL physically cannot store color. If you’re printing on a multi-color machine, convert to 3MF instead; it carries color and material assignments.
Is my GLB uploaded anywhere?
No. The converter runs as WebAssembly in your tab; your file never leaves your device.
What’s the maximum file size?
No hard cap — processing is local. Above ~200 MB, parsing may take a while on low-RAM devices.
