History
editNitro Software was founded in Melbourne, Australia to developed PDF software as an alternative to Adobe Acrobat.[4]
In 2015, the company had sold 1 million licenses.[4]
In June 2021, the company acquired PDFPen, a PDF editing app for Mac, iPad, and iPhone.[5]
Controversy
editIn May 2025, the company sent a letter to all owners of perpetual licenses older than version 13, informing them that their previously lifetime license will be deactivated unless they 'upgrade' to a subscription model.[6]
As of June 2025, Nitro Software was graded F by the Better Business Bureau for the company's failure to respond to customer complaints.[7] As a result, Nitro Software is no longer rated by Better Business Bureau.[8]
