About PDFPDF – Portable Document Format – is an electronic document format designed by Adobe. PDF provides several advantages over other electronic document formats:

- 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
