GLB to STL
Convert your GLB file to STL, right in the browser.
Your model goes here.
Choose your file or try the original sample below. No installation or sign-up.
01 / HOW IT WORKS
Open, inspect, then use your result.
- 01
Open your file
Choose, drop or paste your GLB file. All three input methods use the same local checks.
- 02
Look from every angle
Orbit, zoom and switch between standard views. Read the dimensions and object count beside the model.
- 03
Download the converted file
After conversion, download STL. Open the result in your destination software and check the units before use.
02 / TRY IT YOURSELF
A real file. A result you can check.
This original four-hole plate measures 80 × 50 × 8 mm. The sample uses the input format for this page. Use the default unit and axis settings to reproduce those dimensions.
Original public sample. Your uploads are never added to this gallery.

03 / FORMAT & USE
GLB to STL
Extract static triangle geometry from a GLB for an STL workflow. Scene transforms are applied, metre coordinates become millimetres and Y up is converted to Z up.
What this viewer supports
STL discards materials, textures, transparency and object hierarchy. Only supported static mesh geometry is exported; no animation posing, skin baking or mesh repair is performed.
Supports files up to 32 MiB, 1 million triangles and 2,000 mesh objects. For larger assemblies, export only the parts you need.
04 / QUESTIONS
Know your input. Understand your output.
Will transparent surfaces or colours be preserved in STL?
No. STL has no material or transparency model. The triangle geometry is exported regardless of its display material, so inspect the result before slicing.
Do I need an account or credits?
No. These tools are free and run in your browser. No account, subscription or credits are required.
Is my model uploaded?
No. Your selected file is read and processed in this browser. The page downloads its CAD engine and public samples, but does not upload your model. Refreshing or leaving the page clears the current file from the tool.
How are units and orientation handled?
Dimensions use millimetres with Z up. GLB uses metres with Y up; exported STL is mm/Z-up and OBJ is mm/Y-up.
Can I paste a file from my computer?
Copy a file in your file manager, then paste here. Your browser must expose the clipboard as a file; a copied path or text will not open a model.
