## What it is
A framework-agnostic embedded file preview SDK for web applications that renders PDFs, Office documents, images, media, archives, emails, CAD drawings, 3D models, GIS data and more inside a single DOM container. It ships a plugin-based core with adapters for vanilla JavaScript, React, Vue, and Svelte.

## Use cases
- preview pdf and office documents in a web app
- embed file attachment preview in my application
- view zip archives and eml emails in the browser
- show cad dwg dxf drawings on a web page
- preview 3d glb stl models in react
- display geojson and kml map files in a viewer
- framework-agnostic file preview for vue and svelte

## When to choose
- you need in-page preview of many file formats without opening new windows
- your app mixes React, Vue, Svelte or vanilla JS and wants one shared preview core
- you want plugin-based extensibility for custom or proprietary formats
- you need production features like toolbars, themes, error states and multi-file queues

## When to avoid
- you only need PDF rendering and a lighter dedicated PDF library suffices
- you need server-side document conversion rather than client-side preview
- your target formats require optional dependencies you cannot ship
