MiConvert vs CloudConvert
A CloudConvert alternative for 3D models, CAD and OFD
CloudConvert is a strong general converter with a well-known API. It does not convert 3D model formats or Chinese OFD documents, and that is most of what people bring to MiConvert. This page compares the two on the conversions and limits we checked on 13 November 2026.

We opened CloudConvert's page for each pair on 13 November 2026. STEP to STL, STL to OBJ and OFD to PDF answered "This conversion type is not supported"; its CAD section lists DWF, DWG and DXF only.

Where CloudConvert is better
- Bigger free files: 1 GB against MiConvert's 100 MB on a free account.
- A full API with connectors for automation platforms such as Power Automate, plus team billing, a 99.9% SLA and SSO on its business plans.
- Pay-as-you-go credits that never expire, if you convert in bursts rather than every month.
Where MiConvert is better
- 3D models: STEP, IGES, STL, OBJ, 3MF, GLB, FBX, PLY, DAE and more convert to each other, with a 3D preview.
- OFD, the Chinese fixed-layout format used for e-invoices, opens and converts to PDF.
- No account needed for files up to 50 MB, and no daily cap: the free limit is 10 conversions an hour.
- Browser tools that never upload your file, such as the lithophane maker.
Questions
Is MiConvert free like CloudConvert?
Both have a free tier. CloudConvert gives 10 conversions a day once you sign up. MiConvert converts files up to 50 MB without an account, up to 100 MB with a free account, at 10 conversions an hour.
Can CloudConvert convert STEP to STL?
Not when we checked on 13 November 2026: its STEP to STL page said the conversion type is not supported, and its CAD converters cover DWF, DWG and DXF. MiConvert converts STEP and IGES to STL, OBJ, 3MF and other mesh formats.
Should I switch from CloudConvert?
Not if you need a production API with an SLA, or 1 GB files on a free plan: CloudConvert is better there. Use MiConvert for 3D and CAD files, OFD documents, and when you do not want to create an account.
