Glyph & Cog designs and implements software for manipulating electronic documents. Current offerings include software libraries, components, and consulting services related to reading, viewing, and converting PDF files.

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.

Glyph & Cog owns and maintains the open source Xpdf project. The Xpdf code and expertise provide the base for our libraries and consulting services. Our commercial licensing options allow you to incorporate the Xpdf code into your own applications.

If you're interested in our existing products, if you'd like to discuss custom work, or if you just have questions, please don't hesitate to contact us.
