If you sell ebooks online (or want to), you have to make your ebooks available to as many people as possible. For that reason, most authors use PDF format.
PDF stands for Portable Document Format. This format was created by a company called Adobe Systems to allow people to share their files no matter what kind of software they had, or even what kind of computer they had.
To read PDF files, you just need a free tool called Adobe Acrobat Reader, which you can download from adobe.com.
Now, the best way to create PDFs is to use Adobe Acrobat (also available at adobe.com). It makes sense, doesn’t it, since Adobe created this particular format?
Adobe Acrobat, however, is not free. At the time of this writing, the software is $299.00. If that amount is out of your reach right now, it is possible to create your PDFs for free until you are able to invest in Adobe Acrobat.
