OpenPDF is a free, open-source application that lets users read and edit PDF files without Adobe Reader or other Adobe programs.

The Portable Document Format or PDF is a file format developed by Adobe Systems. The goal of PDF is twofold. The first part is to encapsulate all aspects of a document, including text, graphics, layout information and so forth. PDF achieves this objective well. The second part is to deliver this encapsulation in a manner that’s independent of hardware and software. This is an objective that isn’t universally realized. Most users who need to read a PDF have to download and run Adobe Reader.

With OpenPDF, the developers seek to make PDF more accessible. While Adobe Reader is an option, it is a cumbersome solution in many environments and doesn’t support editing fully. Other alternatives exist as well, but OpenOffice, for instance, which is a very popular application, is an entire suite of tools. OpenPDF, on the other hand, is a standalone program with a very small footprint. It runs fast and efficiently and doesn’t demand a lot of resources in order to get the job done.

Released under the GNU General Public License, OpenPDF goes beyond basic PDF support. In fact, it supports PDF signature as well as PDF forms up to the 1.6 specification. It has AcroJS support and XFA scripting support, and in addition to allowing you to read complex PDF documents, you can edit, validate, save and print them. In addition to signing documents, you can select digital certificates and even attach files. In addition to format validation, OpenPDF support mandatory validation as well as automatic calculations.

One issue with OpenPDF is that it’s on a slow development track. This isn’t a big problem in terms of functionality. OpenPDF was designed to handle a particular job, and it does that quite well. Nevertheless, the program was developed in Spanish, and although the installer supports language selection, translations haven’t been provided beyond that installer yet. This will extend the learning curve for those that don’t read Spanish, but the menu system isn’t complex, and most users will be able to overcome this challenge in order to use what continues to be one of the top PDF programs available.
