## What it is
Online 3D Viewer is a free, open-source web application and JavaScript library for visualizing and exploring 3D models directly in the browser, built on three.js and WebGL. It supports importing many 3D file formats (gltf, stl, obj, step, ifc, fbx, and more) and exporting to several common formats.

## Use cases
- view 3D models in the browser without installing software
- embed a 3D model viewer in my website
- preview STL files before 3D printing
- convert 3D models between formats like gltf, obj, and stl
- inspect STEP or IGES CAD files online
- explore glTF models with measurements and camera controls

## When to choose
- you need a browser-based 3D viewer with broad format support
- you want to embed 3D model viewing in a web app via a JavaScript library
- you need a free, self-hostable alternative to proprietary 3D viewers

## When to avoid
- you need offline desktop CAD editing or modeling tools
- you require server-side rendering or headless 3D processing
- you need formats not listed among its supported imports/exports
