According to Wikipedia, freeware is copyrighted computer software which is made available for use free of charge, for an unlimited time, as opposed to shareware where the user is required to pay (e.g. after some trial period or for additional functionality). Authors of freeware often want to "give something to the community", but also want credit for their software and to retain control of its future development. Sometimes when programmers decide to stop developing a freeware product, they will give the source code to another programmer or release the product's source code to the public as free software.

Using doPDF you can freely convert documents to searchable PDF files from any Windows application. It installs as a printer driver and helps you generate the PDF files by simply selecting the "print" command from any application (you can convert your Word documents, Excel sheets, PowerPoint presentations, AutoCad drawings, company’s reports, contracts, workflows, agreements, marketing plans, forms, products list, price list, charts, emails or web pages). The resulted PDF files can be viewed on any computer with a PDF viewer (reader) installed.
