CAD Exchanger
Desktop app and SDK that read, heal and convert over 30 CAD and mesh formats. A translator, not an authoring tool.
3D Viewers
3D viewers let you inspect, share and embed models without installing a full 3D suite. The category spans free web viewers for quick checks, platforms for publishing interactive models, and enterprise viewers for reviewing large CAD assemblies. Privacy of uploaded files is a real differentiator here.

3D Viewers: frequently asked questions
How can I view a 3D model without installing software?
Browser based viewers open common formats such as GLB, OBJ and STL directly, including the free viewer on this site. Files either stay local in your browser or are uploaded to a service, so check which one a viewer does before loading confidential work.
How do I embed an interactive 3D model in a website?
Publishing platforms provide an embed code similar to a video embed. For full control you can self host with open source libraries such as three.js or model-viewer, which render glTF models natively in the browser.
Why does my model look wrong in a viewer?
The usual causes are missing texture files, materials the format cannot carry, flipped normals or unit scale differences. Exporting to GLB with textures embedded removes most of these problems.
