The PDF format (Portable Document Format) is the most used format to send documents that can't be altered over the Internet. The only problem is that the vast majority of people can't pay for the application to create and manage PDF files par excellence, Adobe Acrobat.
A great alternative to Adobe Acrobat
But in the last few years, this problem has been solved with the launch of applications, like doPDF, that allow us to create PDF files by means of a virtual printer.
Ideal if you're looking for a free tool that will allow you to create PDF files.
When doPDF is installed on a computer, the only possibility that its interface offers us is to choose a file and transform it into a PDF file, this is mainly due to the fact that its interface isn't the important part of this application, it's actually the virtual printer that it creates when installed. The virtual printer will allow the user to create PDF files from any application that offers us the possibility to print, only requiring to choose the virtual printer instead of the normal printer.
