3D Model Converter

3D Model Converter's Overview

3D Converter is a free online 3D model converter for common mesh and scene files, designed for local browser-based conversion of STL, OBJ, PLY, GLB, and glTF files. It lets users preview models, check format-specific changes, and download a validated output without signing up or uploading files to a server. The tool emphasizes privacy, dependency-aware handling for OBJ and glTF packages, before-and-after validation, and honest reporting of feature loss such as materials, textures, hierarchy, animation, units, and axis data. It also includes a private 3D viewer for inspecting geometry, dimensions, and mesh statistics before conversion.

3D Model Converter's Pricing

Browser-local conversion routes and the 3D viewer are free to use without an account. The page also notes a 100 MB limit for the main local model file. Cloud CAD processing, saved history, and account storage are separate from the free local workflow.
