PDF – Portable Document Format – is an electronic document format designed by Adobe. PDF provides several advantages over other electronic document formats:
- PDF captures all formatting and layout information (unlike HTML)
- PDF is easy to generate - if you can print it, you can convert it to PDF
- PDF is portable across all common computing platforms
- PDF is an open specification
Because of this, PDF has become the de facto standard for electronic documents.

When selecting a PDF software vendor, make sure you pick one who knows PDF!
