We all have a huge collection of patterns that are not in PDF format. Some are html, some are paper patterns or in books. The very good news is that it is pretty easy to create a PDF from these other formats, right from your iDevice.

kC is not affiliated with any of these apps or websites, and I’m not sure I have an opinion on what is the “best” sometimes it just depends. And this is by no means an exhaustive list of the options, but it should get you started. For more feedback from a wide range of users visit our Ravelry Group.
