## What it is
A browser-native file preview library that renders Office documents (DOCX, XLSX, PPTX), PDF/OFD, CAD files (DWG, DXF), archives, email, diagrams, 3D, and media directly in the browser without server-side conversion. It ships adapters for Vue, React, Svelte, jQuery, and Web Components, with WASM workers and assets that can be self-hosted for private deployments.

## Use cases
- preview docx files in a web app without a conversion server
- render dwg and dxf cad drawings in the browser
- embed pdf and office document preview in an internal web app
- preview xlsx and pptx files client-side
- self-host a document viewer so private files never leave the network
- add file preview to vue or react applications
- preview email and archive files in the browser

## When to choose
- you need in-browser preview of Office, PDF, or CAD files without uploading them to a SaaS converter
- your app is internal/private and files must stay on your network
- you want one viewer API across many formats and frameworks
- you need offline-capable preview with self-hosted WASM and font assets

## When to avoid
- you need pixel-perfect fidelity for complex Office documents that only server-side conversion provides
- you only need simple PDF viewing and a lighter-weight pdf.js wrapper suffices
- your target formats require heavy server-side rendering unsupported by browser parsing
