Nitro PDF Software revolutionised the market for PDF software in April 2005 when it launched the world's first true alternative to Adobe Acrobat - Nitro PDF Professional. Nitro PDF Professional lets users create, convert, edit, secure, manipulate and collaborate using PDF.
Nitro PDF Professional has won multiple "Product of the Year" and "Top Buy" awards and is sold internationally in retail stores, online, and through corporate resellers and VARs.
In March 2007, Nitro PDF Software launched Nitro PDF Express - a fast, lightweight PDF creator and converter. As with the release of Nitro PDF Professional, Nitro Express broke new ground for PDF software value. In December 2007, Nitro PDF Software acquired PDF Download, one of the Web's most popular PDF products.
Nitro PDF software is used by hundreds of thousands of businesses worldwide, with customers including American Airlines, Bank of America, Disney, General Motors, Hewlett Packard, IBM, the US Department of Defense, the US Department of Energy, the US District Courts, and Microsoft.
Nitro PDF Software is jointly headquartered in San Francisco, California and Melbourne, Australia; with operations spanning the US, Europe, Asia and Australia.
