About this 3D converter
Convert compatible STEP/STP files to GLB online when you need a browser-friendly 3D asset for web pages, product previews, real-time scenes, or simple sharing. Processing happens locally in your browser; source-format features that GLB cannot represent may not transfer.
Why convert STEP/STP to GLB?
Convert compatible STEP/STP geometry to a compact, browser-friendly GLB when you need easier web sharing, product previews, or real-time 3D delivery. This page previews the imported result before download.
What is preserved in the STEP/STP to GLB conversion?
The export focuses on compatible geometry and supported materials or animation data. Source-specific CAD history, application metadata, avatar settings, or unsupported effects may not transfer, so always review the downloaded GLB file before publishing.
Private browser processing
After sign-in and the one-time $1.90 format unlock, compatible conversion runs locally in your browser. Your source file is not uploaded to a conversion server by this workflow.
STEP and STP files from SolidWorks, Fusion 360, FreeCAD, and CATIA
Use a current desktop browser on Windows, macOS, or Linux to inspect compatible STEP or STP exchange files from SolidWorks, Fusion 360, FreeCAD, CATIA, Creo, or similar CAD software. The browser shows a tessellated display mesh, not native feature history, PMI, or manufacturing validation.
How to use this STEP converter
- Sign in and unlock this conversion once.
- Choose a compatible STEP/STP file from your computer.
- Preview the tessellated or imported result, then download the exported GLB file.

STEP converter FAQ
How do I convert STEP/STP to GLB online?
Unlock this STEP/STP to GLB converter once, choose a compatible source file, then preview and download the result in your browser.
Why convert STEP/STP to GLB?
GLB is a web-friendly format for browsers and real-time 3D workflows. The conversion makes compatible geometry easier to preview and share.
Are all source-format features preserved?
Not always. Source formats can contain application-specific materials, metadata, CAD precision, or avatar data that a web-ready export cannot retain. Review the result before publishing.
Do I need to install a STEP/STP to GLB converter?
No. This compatible STEP/STP to GLB conversion runs in a current browser after sign-in and the one-time format unlock.
Will every STEP/STP feature appear in the exported GLB?
Not necessarily. Review geometry, scale, orientation, materials, textures, and animations after export because source-specific data may not have a GLB equivalent.
Can I view a STEP or STP file from SolidWorks, Fusion 360, or FreeCAD?
Yes, for compatible exchange geometry. This is a local tessellated browser preview; use the CAD application for feature history, assemblies, tolerances, PMI, and engineering validation.
Is STEP to GLB conversion processed online?
Compatible conversion is processed locally in your browser. Your source model is not uploaded to a conversion server by this workflow.
What should I check after converting STEP?
Open the exported GLB and review geometry, scale, orientation, materials, and any animation before using it in a production scene or web page.
Is this STEP converter a subscription?
No. The format unlock is a one-time $1.90 purchase; VIP members can also access the tool.
