Some free PDF tools give you limited access to interactive features, but what if you want to go further? Perhaps you need to make minor alterations to the actual PDF document itself, or want to split or combine multiple documents into a single file? In the past, actually editing a PDF document meant an expensive purchase, but now Nitro Pro brings all the advanced functionality you need within the reach of individuals and small businesses too.

But PDF files need to do more than simply replicate the original design of a document – they’ve become increasingly interactive, with form-filling, annotations, digital signatures and much more. These days, you can create PDFs without having to shell out for the privilege – once of the best free tools for creating PDFs comes in the form of the excellent Nitro Reader. It doesn’t matter what application has been used to create the original document, by exporting it as a PDF you ensure it won’t change appearance when viewed elsewhere.

PDF files are quite simply the best means of sending a document to somebody else in a format you’ll know will appear exactly as you intend it to on their computer.
