In Safari when you download a page you should be able to save as a PDF or open with a new program such as IBooks for example. Under the forward arrow drop box ( same one where you have the "add a bookmark" option) there should be an option entitled "Open In".
This would allow you to open page in a number of alternative programs and thus save file.
On my IPad there is no such option.
Any idea why and how to rectify please?
