Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange. The format includes a subset of the PostScript page description programming language, a font-embedding system, and a structural storage system.
Over the years PDF has become an extremely important file format. If you want to create documents that can be viewed under all major operating systems, PDF is the ticket, as it maintains the overall look and feel of documents regardless of what platform they are viewed under.
This article focuses on useful PDF tools which can help you create PDFs as well as small utilities/libraries that help you work with PDF. It doesn’t seek to overlap with our articles on PDF manipulation tools and PDF viewers as they are covered in separate articles.
Here’s our verdict captured in a legendary LinuxLinks chart. Only free and open source software is eligible for inclusion.
Let’s explore the 21 PDF tools at hand. For each title we have compiled its own portal page, providing a screenshot of the software in action (where appropriate), a full description with an in-depth analysis of its features, together with links to relevant resources.
