What it is

3D Model Converter is a web tool for viewing and converting mesh files between modeling, CAD, 3D-printing, and web workflows. It lists STL, OBJ, PLY, 3MF, FBX, GLB, glTF, STEP, and IGES support. STL, OBJ, PLY, GLB, and glTF files can be parsed locally in the browser without sending them to the server, while STEP and IGES use a cloud conversion route after a verified upload begins. The main local model file limit is 100 MB, and large dependency packages can meet browser memory limits. OBJ and glTF workflows may require accompanying MTL, BIN, and image files. After export, the tool reopens the result and rejects files that cannot be parsed or contain no renderable triangles. Reports compare available dimensions, triangles, objects, materials, textures, units, and axis data. The Free plan costs nothing and includes unlimited local workflows, five cloud credits monthly, 24-hour cloud history, and a 50 MB cloud-file limit. Pro costs $9.90 a month and adds 100 cloud credits, 30-day history, priority queue, and batches of up to 20 files.

Spec sheet

Purpose
3D Converter provides browser-local mesh viewing and conversion for handoffs between modeling tools, 3D printers, and the web.Read 30 Sep 2026 · 3dconverter.org
Intended users
The maker describes the product as serving practical workflows involving CAD, printing, modeling tools, and the web.Read 30 Sep 2026 · 3dconverter.org
Support
The site lists [email protected] and provides a contact form.Read 30 Sep 2026 · 3dconverter.org
Cloud processing
STEP and IGES use a separate cloud conversion path after a verified user starts an upload.Read 30 Sep 2026 · 3dconverter.org
Dependencies
OBJ and glTF workflows can require selecting referenced MTL, BIN, and image files together with the model.Read 30 Sep 2026 · 3dconverter.org
File size limit
The homepage limits the main local model file to 100 MB; large dependency packages may encounter browser memory limits.Read 30 Sep 2026 · 3dconverter.org
Local processing
STL, OBJ, PLY, GLB, and glTF routes parse selected files in the browser without sending those files to the server.Read 30 Sep 2026 · 3dconverter.org
Notable limitation
The site says conversion does not repair non-manifold geometry, fill holes, remove self-intersections, or create printable wall thickness.Read 30 Sep 2026 · 3dconverter.org
Quality report
The report compares dimensions, triangles, objects, materials, textures, units, and axis data when available.Read 30 Sep 2026 · 3dconverter.org
Security and privacy
The privacy policy says the service implements appropriate security measures to protect personal information from unauthorized access, alteration, disclosure, or destruction.Read 30 Sep 2026 · 3dconverter.org
Supported formats
The site lists STL, OBJ, PLY, 3MF, FBX, GLB, glTF, STEP, and IGES as supported formats.Read 30 Sep 2026 · 3dconverter.org
Validation
After export, the tool reopens the output and rejects files that cannot be parsed or contain no renderable triangles.Read 30 Sep 2026 · 3dconverter.org

Strong points and limits

Strong points

  • Supports nine listed 3D formats
  • Local browser parsing for several formats
  • Export validation checks renderable triangles
  • Quality report compares model properties
  • Pro batches up to 20 files

Limits

  • Local main model files limited to 100 MB
  • STEP and IGES use cloud processing
  • Conversion does not repair mesh defects
  • Pro costs $9.90 a month

Who it suits

3D Model Converter suits people moving files between CAD, modeling tools, printers, and the web who want browser-local mesh handling or cloud conversion. It supports both individual conversions and Pro batches.

Verdict

3D Model Converter provides a clear split between private browser-local mesh workflows and cloud conversion for STEP and IGES. Its validation and comparison report help check outputs, but geometry repair is outside the conversion process.
