If you ever read PDF files on your computer and you don't have the official (free but huge) Adobe program installed, it's a fair bet that you're using Nitro PDF instead. This free program, loved by tens of millions of people around the world, opens PDF files quickly and efficiently but doesn't suffer from the unnecessary bloat that the Adobe product does.

But what about if you want to create a PDF file, rather than simply read one? How easy is that? And what would it cost? The answers turn out to be "very" and "nothing".

Primo PDF, from the people behind the Nitro PDF reader, is a Windows printer driver. Install it on your PC and then open any program. Create some data and then, from the File menu, choose Print. Alongside your normal printer, you'll see a new option. You can now "print" to a PDF file. Which means that, instead of your output appearing on paper, you'll end up with a PDF file that looks just like the paper-based version would have.

This means that you can now use almost any program on your PC to create PDF files.

Primo PDF is free, and is a 7 MB download. The program is malware-free according to VirusTotal and Web of Trust.  Read More
