ViewerJS is a JavaScript document viewer that renders PDF and OpenDocument Format (ODF) files directly in the browser, built on top of PDF.js and WebODF. It is self-hosted on your own webserver with no external dependencies, plugins, or third-party services required.

- display odt documents in browser
- show odp presentations on my site without plugins
- self-hosted document viewer for intranet
- render openoffice documents in a web app
- view spreadsheets in browser without google docs
- present slides directly from the browser
When to choose
- you need to display PDF or ODF documents on your own site without third-party services
- privacy matters and you cannot send documents to hosted converters like Google Docs or Zoho
- you need offline-capable document viewing with embedded font support
When to avoid
- you need to view proprietary formats like DOCX or XLSX natively
- you want a maintained library with active development and clear licensing
- you need AGPL-incompatible commercial use without purchasing a license
