The software developer said that it was "fighting for a place on the corporate desktop" alongside the likes of Adobe, Google and Microsoft following the release of its latest product.
Global Graphics chief executive Gary Fry added: "Businesses should no longer need to pay for simple PDF creation and we hope our disruptive pricing strategy will begin to redraw the lines of this market."
The PDF software allows the creation of PDF, PDF/a or XPS documents from any Windows application that prints, from the Microsoft Office toolbar or from a drag-and-drop menu.
In addition, gDoc Creator allows the conversion of PDFs to Microsoft Word documents and includes a "flick view" feature that enables quick browsing between documents.
"Offering so much functionality for free will drive adoption in large enterprises at a time when their budgets are under extreme pressure," said Fry. "It also makes the basic free PDF software tools obsolete and puts real pressure on low-end paid-for PDF software."
The free PDF software is available for download by individual office workers and consumers, as well as under a corporate licensing scheme, and features a simple upgrade pass to gDoc Fusion, which allows document creation across multiple formats including Word, Excel PowerPoint, PDF, XPS, JPG, TIFF and PNG.
