To get PDF files of the factory service manual (not the owner's manual), go to hmaservice and select your car under "Shop". You will see the main categories of the service manual, i.e. General Information, Engine Mechanical System, etc. There are usually about 15 categories. To the right of each main heading is a printer icon. If you have a print-to-pdf driver installed (like PrimoPDF) you can print each category to create a PDF file. Each category prints as one long PDF file, so you end up with about 15 PDF files. This is generally the same thing people are selling on eBay. It is piracy, but since Hyundai provides the online manuals at no cost they aren't losing sales so they probably don't care. Or, Hyundai doesn't know about the eBay sellers.
For the other sections, ETM, DTC, TSB, etc. on hmaservice, you would have to print each page individually and would end up with hundreds of pages. Not practical to do. But, having the service manual as PDF files is a good thing to have on a tablet or smartphone so you have repair information handy should a problem happen on the road.
