3D Model Converter
What it is
3D Model Converter is a web tool for viewing and converting mesh files in workflows involving CAD, modeling tools, 3D printers, and the web. It supports STL, OBJ, PLY, 3MF, FBX, GLB, glTF, STEP, and IGES. STL, OBJ, PLY, GLB, and glTF files can be 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, while large dependency packages can run into browser memory limits. OBJ and glTF workflows may need referenced MTL, BIN, and image files selected with the model. After export, the tool reopens the output and rejects files it cannot parse or that contain no renderable triangles. Its report compares available properties such as dimensions, triangles, materials, textures, units, and axis data. The free plan includes unlimited browser-local mesh workflows, five monthly cloud credits, and a 50 MB cloud-file limit. Pro costs $9.90 a month and includes 100 monthly cloud credits, batches of up to 20 files, and a 100 MB effective cloud-file limit.
For and against
For
- Supports nine listed 3D file formats.
- Several formats are processed locally in the browser.
- Export validation checks for renderable triangles.
- Free plan includes unlimited browser-local mesh workflows.
- Pro supports batches of up to 20 files.
Against
- Main local model files are limited to 100 MB.
- Large dependency packages may hit browser memory limits.
- Cloud conversion uses credits and file-size limits.
- Conversion does not repair mesh geometry.
The verdict
3D Model Converter offers a broad format list, browser-local routes for several formats, and cloud conversion for STEP and IGES. Review its upload limits and mesh-repair exclusions before using it for a specific model handoff.
Who it suits
This web tool may suit people moving mesh files among CAD, modeling, printing, and web workflows. It offers both browser-local mesh processing and cloud conversion for STEP and IGES.
