Nitro Software was founded in Melbourne, Australia, by a team of three, proposed as an alternative PDF software to Adobe Acrobat.[4]

In 2015, the company reported 1 million licenses sold, and in 2018, it launched the Nitro Productivity and eSigning Suite.[4]

In 2018, Nitro PDF Pro was used by more than 650,000 businesses.[5]

In June 2021, the company purchased PDFPen, a Mac, iPad, and iPhone PDF editing app.[6]
