hi all, I've searched quite a bit for the answer to this question but have not found an answer or solution. I'm backpacking around Asia and have been wanting to read a few PDFs, but 99% of the time have no wifi or other connection. I have air shareing etc but don't have a computer to connect to to dled PDFs with. I have insta paper but it stupidly doesn't seem to work with PDFs. Is there an app hat allows you to enter a URL for a PDF then downloads it for offline viewing? Mail app sorts works for this but not long term. Thanks!
