GLB to STL Converter
Processing entirely on your device — large files may take a moment.
STL is what 3D printers and slicing software (Cura, PrusaSlicer) expect — the final step before printing. If your files are still in GLB format, this page is the shortcut: GLB is the compact binary form of glTF — "the JPEG of 3D": one file carrying geometry, materials and textures, made for the web, AR and game engines.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

Frequently asked questions
Is this GLB to STL converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What happens to colors and materials?
The STL format only stores geometry, so colors, textures and materials from the source file are dropped — the shape converts perfectly, appearance does not. If you need materials, convert to GLB instead.
