You could have downloaded PDF2RTFService 1.1 for Mac from our application library for free. This free software for Mac OS X was originally developed by DEVONtechnologies, LLC. The program belongs to Productivity Tools.
From the developer:
PDF2RTFService is a free filter service from DEVONtechnologies that enables any Cocoa application able to read rich text files (RTF), for example TextEdit or Pages, to open Adobe PDF, PostScript (PS) and Encapsulated PostScript (EPS) files as paginated rich text documents. The actual conversion is done by Quartz and the PDFKit of Mac OS X 10.4 "Tiger" and PDF2RTFService post-processes and paginates the output.
