Convert STP to USDZ Online
Convert STP to USDZ in seconds. STP (STEP) is the 3-letter extension for the STEP CAD standard; USDZ's strength is this: a single file ready for iOS AR viewing with no external references. No software installation required — everything runs in your browser.

Why Convert STP to USDZ?
If you need a file built for Apple's AR Quick Look distribution format but only have one built for exact engineering geometry exchange between CAD systems and manufacturers, converting is usually the fastest path — STP (STEP) and USDZ serve different enough purposes that recreating the asset from scratch rarely makes sense.
STP (STEP) is typically produced by or used with SolidWorks, Fusion 360, Inventor, CATIA, for exact engineering geometry exchange between CAD systems and manufacturers. USDZ is expected by iOS AR Quick Look instead, for Apple's AR Quick Look distribution format — converting bridges that gap.
STP (STEP)'s limitation: not readable by mesh-only tools like slicers without conversion. USDZ's strength: a single file ready for iOS AR viewing with no external references — it doesn't share that constraint.
How to Convert STP (STEP) to USDZ
- Upload your STP file.
- MiConvert converts it to USDZ, aiming to preserve what makes USDZ useful: a single file ready for iOS AR viewing with no external references.
- Download the converted USDZ file.
- Use it directly with iOS AR Quick Look.
Key Conversion Features
- Purpose-built for the shift from exact engineering geometry exchange between CAD systems and manufacturers to Apple's AR Quick Look distribution format, not a generic pass-through
- Converts STP into USDZ, aiming to preserve what matters most: a single file ready for iOS AR viewing with no external references
- 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
- No local software installation required for either side — not SolidWorks, Fusion 360, Inventor, CATIA, not iOS AR Quick Look — everything runs in the cloud
- Produces output ready for iOS AR Quick Look, picking up right where SolidWorks, Fusion 360, Inventor, CATIA left off

Frequently Asked Questions
What's the real difference between STP and USDZ?
STP (STEP) is built around exact engineering geometry exchange between CAD systems and manufacturers (the 3-letter extension for the STEP CAD standard). USDZ is built around Apple's AR Quick Look distribution format instead (a zipped, self-contained package of USD) — different enough that this is a genuine format conversion, not just a rename.
Is USDZ objectively better than STP?
Not objectively — USDZ is better specifically for Apple's AR Quick Look distribution format. For exact engineering geometry exchange between CAD systems and manufacturers, STP (STEP) is still the right tool; that's exactly why both formats exist.
Can I convert the file back from USDZ to STP afterward?
Only what USDZ actually carries can come back — anything specific to STP (STEP)'s role in exact engineering geometry exchange between CAD systems and manufacturers that didn't survive the original conversion won't reappear.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
What software works with the converted USDZ file?
USDZ is used by iOS AR Quick Look. If you were working with SolidWorks, Fusion 360, Inventor, CATIA (which produces STP (STEP)), this conversion is the direct bridge between the two.
