Q: Hello everybody Can I move a PDF a document from my ipad air icloud email to icloud drive if so how Thank You for any Help

Tap it in the email to open, tap the share icon in the bottom left corner, choose 'copy to iBooks' or any other app such as PDF expert that will open PDFs,

I'm not sure you can do that on a mobile device.

Maybe I am missing something, but when I do that the PDF shows up I iBooks, but not in iCloud Drive.  I can also save to Dropbox, but I don't see how to save to iCoud.  I was expecting to see an iCloud icon like the Dropbox icon.  Is there something I need to do to turn it on?  I tried the more, but no luck. Is iCloud just not as robust as Dropbox? I have a huge iCloud storage and only a small Dropbox.

Yes that's right, you need to open it in an app that can save it to iCloud drive.

Is there any such app for a PDF?

There are loads of apps for pdf's, you need one that works with iCloud though. I use pdf expert and as I say, I open the pdf from the email in pdf expert, then I save it to iCloud drive.
