Unsurprisingly, Nitro Pro is also tightly integrated with Nitro Cloud, the company’s web-based service for sharing and collaborating on PDF documents with other users. These close ties mean Nitro also ships with plugins for Word, Excel, PowerPoint and Outlook, compatible with 64-bit iterations of Office as well as 32-bit versions.

Nitro Pro’s interface is tied in closely to Microsoft Office 2019, sporting the same user interface to provide familiarity for those moving between the two apps. Throw in form filling, collaboration tools and the ability to combine PDF files from multiple documents, and you have a tool that – if not quite the equal of Adobe Acrobat – is more than capable for most people’s needs at less than a third of the price, even after the recent price rises. Nitro pairs this functionality with a set of powerful editing tools, with both line- and paragraph-based text editing possible alongside the ability to swap out or insert images. This improves with each release, and version 10 introduced an auto de-skew function and improved text, images and table recognition. Unlike free products, Nitro Pro’s PDF creation tools are capable of producing editable files from the likes of Word and Excel documents, while it also comes with a serviceable OCR engine for scanning in editable versions of paper documents too. Nitro Pro is a powerful tool for creating, editing and converting PDF documents.
