Understanding PDF Format

We have been working with PDF files since 1999 and developed complex software to display PDF files. We have learnt a lot about the PDF file format in that time and share our knowledge in the articles below.

There are also a large number of technical terms used with PDF so we have created a Glossary of Terms with all the keywords.

If you are interested in using our software to display your PDF documents (we can rasterize them, convert them to HTML5 or SVG, or provide a complete Java PDF Viewer) pdf why not setup a call with us and see if we can help?

Here is an overview of the topics covered in this article:
