Windows: We've featured many ways to convert single PDFs to editable formats like a Word Doc, but if you work with PDFs regularly, you may need something a bit more robust. Shareware batch converter PDFZilla is free for the next few weeks.
PDFs are an extremely popular document format, but come with the annoying caveat that you can't edit them without an expensive program like Adobe Acrobat. If you find that this is a major hindrance, you can convert them to other editable formats with PDFZilla: it can batch convert any number of PDF files into Word documents, RTF, TXT, Images, HTML and more in just a few clicks. It's pretty convenient if all you need to do is jump in a document and do some tweaks.
PDFZilla is normally $US29.95, but you can grab it for free right now until February 5th, 2011. PDFZilla is for Windows only.
