can i download a pdf to ipad to read later offline?
No problem. I prefer using the free Adobe Reader app.
Yes - you just need an app that supports PDFs e.g. the free iBooks or Adobe Reader apps
iBooks is free and will be suitable.
You should use "iBooks" by Apple for this. After it is downloaded, view the PDF via Safari or Mail and you should see the "Add to iBooks" button.
