Nitro PDF Professional also provides plenty of power for working with PDFs created by others. You can create PDF-based fillable forms complete with advanced support for field controls and JavaScript actions. Once created PDFs can be enhanced and embellished by assembling multiple files, cropping pages, editing text, adding headers and footers, Bates numbering, links and more. This takes the form of a Nitro PDF ribbon tab, which provides additional functionality including support for links, bookmarks and security, as well as the option to create your PDF and email it directly. Crucially for its target market, Nitro PDF Professional also provides built-in macro-based support for the main Microsoft Office 2007 apps: Word, Excel and PowerPoint. To create your PDFs, you can convert a wide range of file formats directly from the main Nitro PDF application, or you can select the Nitro PDF printer driver and output to PDF from any application. Most importantly, Nitro PDF Professional 6’s engine produces smaller files that are faster to open and which, on average, are created in less than half the time than with the previous version. You can also now save files that are compliant with the PDF/A-1b archiving specification and store all conversion settings for later re-use. This now provides greater control over parameters such as font embedding, image compression and security. So what does Nitro PDF Professional let you do? First, you need to be able to create your PDF, and Nitro PDF Professional 6 sees a complete overhaul of its conversion engine.

You can start making the most of your PDFs immediately. Even better, this interface ties in so seamlessly with the main Office 2007 apps there’s effectively no learning curve. With separate tabs for each of the main tasks – review, forms, view and so on – it’s a model of clarity.

Where the Adobe program scatters its functionality through a confusing mix of dropdowns and toolbars, the Nitro PDF Pro interface is based on an Office 2007-style Ribbon. Nitro PDF Professional’s main aim is to duplicate Acrobat Standard, but thankfully that isn’t the case when it comes to the interface.
