Convert STEP to OFF Online
Convert STEP to OFF in seconds. STEP is the ISO 10303 CAD exchange standard; OFF's strength is this: a plain, easy-to-parse mesh structure. No software installation required — everything runs in your browser.

Why Convert STEP to OFF?
STEP works well for exact engineering geometry exchange between CAD systems and manufacturers, but has a real limitation: not readable by mesh-only tools like slicers without conversion. Converting trades that for this: a plain, easy-to-parse mesh structure.
If you need a file built for geometry-processing research and academic mesh exchange but only have one built for exact engineering geometry exchange between CAD systems and manufacturers, converting is usually the fastest path — STEP and OFF serve different enough purposes that recreating the asset from scratch rarely makes sense.
OFF was built around geometry-processing research and academic mesh exchange, which is precisely the gap STEP leaves open, since it's designed around exact engineering geometry exchange between CAD systems and manufacturers instead.
How to Convert STEP to OFF
- Upload your STEP file.
- MiConvert converts it to OFF, aiming to preserve what makes OFF useful: a plain, easy-to-parse mesh structure.
- Download the converted OFF file.
- Use it directly with geometry-processing research tools.
Key Conversion Features
- Bridges the gap between STEP's focus on exact engineering geometry exchange between CAD systems and manufacturers and OFF's focus on geometry-processing research and academic mesh exchange
- Purpose-built for the shift from exact engineering geometry exchange between CAD systems and manufacturers to geometry-processing research and academic mesh exchange, not a generic pass-through
- Produces output ready for geometry-processing research tools, picking up right where SolidWorks, Fusion 360, Inventor, CATIA left off
- 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
- Fast turnaround, typically under a minute per file

Frequently Asked Questions
Why does OFF 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 OFF is aimed at geometry-processing research and academic mesh exchange. Neither format is "better," they just fit different parts of a workflow.
Is OFF objectively better than STEP?
Not objectively — OFF is better specifically for geometry-processing research and academic mesh exchange. For exact engineering geometry exchange between CAD systems and manufacturers, STEP is still the right tool; that's exactly why both formats exist.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Is the conversion from STEP to OFF reliable?
Straightforward files convert reliably. STEP's limitation — not readable by mesh-only tools like slicers without conversion — combined with OFF expecting geometry-processing research and academic mesh exchange, means unusual or edge-case source files can occasionally need a second look.
