Add your 3MF file
Drop one or more .3mf files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .3mf mesh to .usdz rewrites the same triangles for a different toolchain. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .3mf mesh to .usdz rewrites the same triangles for a different toolchain. 3MF, the 3D Manufacturing Format with extension .3mf, is the modern replacement for STL in 3D printing. One .3mf file carries a complete print job — watertight meshes with declared units, colors, materials, multiple objects, and even slicer settings — inside a compact ZIP-based package.
A .usdz file is a single-file package containing a USD scene together with every texture and asset it references. It is an uncompressed ZIP archive with strict alignment rules, so its contents can be read straight from disk without unpacking — which is what makes it viable as a mobile AR format. For this route the practical draw is one file carries the whole scene, textures included — no missing-asset problems and native, zero-install rendering across Apple platforms — balanced against uncompressed by design, so packages are considerably larger than a compressed equivalent, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .3mf, ecosystem support outside 3D printing is still thinner than OBJ or STL. Switching to .usdz buys you one file carries the whole scene, textures included — no missing-asset problems, which is why it is the better fit for publishing an AR model that opens directly on iPhone and iPad with no app. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | 3D Manufacturing Format (.3mf) | Universal Scene Description ZIP (.usdz) |
|---|---|---|
| Format type | Vector — resolution-independent geometry instead of pixels | Container — quality depends on the codecs and settings inside |
| How it stores data | an OPC package — the same ZIP-with-XML convention as .docx — whose 3D payload is an XML model part | the package is a ZIP with STORED entries only — never deflated — so readers can memory-map the payload in place |
| Strongest at | saving complete print projects with slicer settings preserved | publishing an AR model that opens directly on iPhone and iPad with no app |
| Weak spot | ecosystem support outside 3D printing is still thinner than OBJ or STL | uncompressed by design, so packages are considerably larger than a compressed equivalent |
| Metadata | the core specification defines metadata elements for title, designer, description, license, and creation date, and vendor extensions attach slicer and production settings | uSD layer metadata — up-axis, metres-per-unit, default prim — is present in the package; the geometry-only targets cannot carry it |

Select .usdz in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if USDZ is selectable, the route is real and validated.
Press Convert. The mesh is parsed, retriangulated where needed, and rewritten locally with full validation.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid USDZ file. Outputs keep the original filename with the .usdz extension.
The conversion is exact at the resolution you rasterize to — vectors have no pixels until they are drawn. Pick dimensions that match the largest size you will display, because unlike .3mf, a .usdz raster cannot be enlarged cleanly afterwards.
Yes — the .3mf file is processed inside your browser tab and never uploaded. The mesh is parsed, retriangulated where needed, and rewritten locally with full validation. Close the tab and the file is gone from memory.
iOS and macOS render USDZ natively through AR Quick Look and Preview; Blender, Maya, Houdini, Omniverse and Adobe Aero import it. Android relies on separate viewers and generally prefers glTF. Novus Convert both reads and writes USDZ locally: it is the output of eleven mesh routes as well as an input of its own, which is why promoting it unblocked far more pages than its own.
It depends on the content: the package is a ZIP with STORED entries only — never deflated — so readers can memory-map the payload in place. Convert one representative file first and compare before batch-processing a large set.
In .3mf, the core specification defines metadata elements for title, designer, description, license, and creation date, and vendor extensions attach slicer and production settings. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .3mf → .usdz → .3mf is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
