PDF (Portable Document Format) is rightly popular as a cross-platform means of exchanging documents, allowing those documents to be read on any type of system, irrespective of the operating system and application software that was used to originate it. So, for example, it would permit a document created using OpenOffice under Mac OS X to be read on a Windows PC without the need to install OpenOffice. Also see: How to edit PDFs for free.
We put six PDF editors through their paces and present our findings here. In addition to allowing you to create PDF documents, these packages let you edit your PDF files without the laborious process of editing the original source file in its native format and re-converting it to PDF. In addition, most of them also provide advanced features such as form creation, digital signature and ID certification, and collaborative review and commenting, that you generally don’t get with free PDF packages. We also take a look at one free package to see just how much you can get without spending a penny.
