About This Tool
Preparing Web 3D models for 3D printing requires converting GLB binary files to STL mesh format. This tool extracts geometry from GLB files and generates clean STL output compatible with popular slicers like Cura, PrusaSlicer, and Chitubox.

Frequently Asked Questions
Will textures and colors be preserved in the STL file?
No. STL is a geometry-only format that stores mesh data without textures, colors, or materials. Only the shape and surface geometry from your GLB file will be converted. If you need color information, consider converting to 3MF instead.
Is the output STL binary or ASCII?
By default the converter outputs binary STL, which is more compact and widely supported by 3D printing software. You can toggle the format option if you need ASCII STL for debugging or manual inspection.
Can the converted STL be used directly for 3D printing?
The converted STL contains the original geometry and can be imported directly into popular slicers like Cura, PrusaSlicer, and Chitubox. We recommend checking that the model is a watertight (closed) mesh before slicing.
How are multiple meshes in a GLB handled?
All meshes contained in the GLB file are merged into a single unified STL file. If you need to process individual meshes separately, consider splitting them in modeling software before converting each one.
Is the conversion secure? Will my data be leaked?
Completely secure. All processing happens locally in your browser — files are never uploaded to any server and data is cleared when you close the page. Your 3D models always stay on your device.
