3D Model Converter
What 3D Model Converter is
3D Model Converter is a web tool for viewing and converting mesh files in workflows involving CAD, modeling software, 3D printing and the web. It supports STL, OBJ, PLY, 3MF, FBX, GLB, glTF, STEP and IGES. STL, OBJ, PLY, GLB and glTF files are parsed in the browser without being sent to the server; STEP and IGES use a separate cloud route after the user starts an upload. The main local model file limit is 100 MB, and large dependency packages may encounter browser memory limits. OBJ and glTF workflows can also need related MTL, BIN or image files. After export, the tool checks whether the result can be parsed and contains renderable triangles. Its report compares available details such as dimensions, triangles, materials, textures, units and axis data. The free plan includes unlimited local workflows and five monthly cloud credits, with a 50 MB cloud-file limit. Pro costs $9.90 a month and adds 100 monthly cloud credits and batches of up to 20 files.
Who it suits
It suits people moving mesh files among CAD, modeling, printing and web workflows, especially when browser-local processing is useful. Users converting STEP or IGES should be prepared for the separate cloud upload route.
What it does well
- Supports nine listed mesh and CAD formats.
- Several file types are processed locally in-browser.
- Export validation checks parsing and renderable triangles.
- Free plan includes unlimited browser-local workflows.
- Pro supports batches of up to 20 files.
What to know first
- Local model file limit is 100 MB.
- Cloud files are limited to 50 MB on Free.
- Large dependency packages may meet browser memory limits.
- Conversion does not repair mesh geometry.
Limits
The free plan includes five cloud credits per month, 24-hour cloud history, a 50 MB cloud file limit, and a standard queue. The main local model file is limited to 100 MB. Pro costs $9.90 a month and has 100 cloud credits monthly, a 100 MB effective cloud file limit, and batches of up to 20 files; team workspaces are excluded.

Getting started
- Open https://3dconverter.org/.
- Choose a supported file workflow: local processing is available for STL, OBJ, PLY, GLB, and glTF; STEP and IGES use cloud conversion.
- Select the model file; include referenced MTL, BIN, or image files for OBJ and glTF workflows when needed.
- Use the free plan or choose Pro at $9.90 a month for its cloud credits and batch conversions.
- Export the converted file and review the output validation and quality report.
Verdict
3D Model Converter covers a broad set of formats and separates browser-local workflows from cloud conversion for STEP and IGES. Its checks assess export validity, but the tool does not fix geometry defects or add printable wall thickness.
Questions
Is 3D Model Converter free?
Yes. Its Free plan costs nothing and includes unlimited browser-local mesh workflows and five cloud credits per month.
How much does Pro cost?
Pro costs $9.90 a month. It includes 100 cloud credits per month and batches of up to 20 files.
Which formats does it support?
Supported formats are STL, OBJ, PLY, 3MF, FBX, GLB, glTF, STEP, and IGES.
Which files are processed locally?
STL, OBJ, PLY, GLB, and glTF routes parse selected files in the browser without sending them to the server. STEP and IGES use a cloud conversion route after an upload is started.
What platforms can I use it on?
The listed platform is web.
Does conversion make a mesh ready to print?
Conversion does not repair non-manifold geometry, fill holes, remove self-intersections, or create printable wall thickness.
