Convert STEP to GLB Online
Convert STEP to GLB in seconds. STEP is the ISO 10303 CAD exchange standard; GLB's strength is this: a single efficient file bundling geometry, materials, and textures. No software installation required — everything runs in your browser.

Why Convert STEP to GLB?
The short version: STEP is optimized for exact engineering geometry exchange between CAD systems and manufacturers, GLB is optimized for fast-loading real-time delivery for web and AR viewers, and this converter exists for the moment those two needs don't line up.
GLB was built around fast-loading real-time delivery for web and AR viewers, which is precisely the gap STEP leaves open, since it's designed around exact engineering geometry exchange between CAD systems and manufacturers instead.
GLB is the compact binary form of glTF, built around fast-loading real-time delivery for web and AR viewers. Converting from STEP — built around exact engineering geometry exchange between CAD systems and manufacturers instead — closes that gap.
How to convert STEP to GLB
- Upload your STEP file.
- MiConvert converts it to GLB, aiming to preserve what makes GLB useful: a single efficient file bundling geometry, materials, and textures.
- Download the converted GLB file.
- Use it directly with Three.js, Babylon.js, iOS/Android AR viewers.
Key Conversion Features
- Free for files up to 50MB, 100MB for registered accounts
- Understands that STEP is the ISO 10303 CAD exchange standard and GLB is the compact binary form of glTF, rather than treating the conversion as a blind format swap
- No local software installation required for either side — not SolidWorks, Fusion 360, Inventor, CATIA, not Three.js, Babylon.js, iOS/Android AR viewers — everything runs in the cloud
- Built to handle the real-world quirks of files meant for exact engineering geometry exchange between CAD systems and manufacturers, not just a textbook version of the format
- Bridges the gap between STEP's focus on exact engineering geometry exchange between CAD systems and manufacturers and GLB's focus on fast-loading real-time delivery for web and AR viewers

Frequently Asked Questions
Do I need any special settings before uploading my STEP file?
No special setup is required — upload the file as-is. STEP files meant for exact engineering geometry exchange between CAD systems and manufacturers convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Why would I need GLB instead of just keeping STEP?
Mainly when your workflow specifically calls for fast-loading real-time delivery for web and AR viewers — that's GLB's whole reason for existing, and STEP isn't built to provide it, since it's focused on exact engineering geometry exchange between CAD systems and manufacturers instead.
Why does GLB exist as a separate format instead of everyone just using STEP?
Because they're built for different jobs — STEP is aimed at exact engineering geometry exchange between CAD systems and manufacturers, while GLB is aimed at fast-loading real-time delivery for web and AR viewers. Neither format is "better," they just fit different parts of a workflow.
Can I convert the file back from GLB to STEP afterward?
Only what GLB actually carries can come back — anything specific to STEP's role in exact engineering geometry exchange between CAD systems and manufacturers that didn't survive the original conversion won't reappear.
