PDFs are the lifeblood of many companies. For businesses that send and receive a large amount of legal documents or other forms, PDFs are much more secure and professional looking than other document types. Unlike other document editor tools, PDFs can only be edited by the creator or those with a password, and information such as how recently the document was edited (and by whom) is hidden. However, sometimes you only need to create a PDF every once in a while, not every day, so you don't want to invest in dedicated PDF software. That's when free PDF editors come in handy. The list we've outlined here includes any document creation solution with an available free offering. They may only support one user or one project, but they're truly free offerings. Scaling, however, will often require full investments.
