How do I save a document to iCloud or OneDrive?

I found a way to do this. Tap briefly on the PDF document in safari. A not-very-obvious bar appears at the top of the document, with "save to iBooks" on the right and "more" on the left. Tap more, then scroll along the available apps until you see OneDrive and "import with OneDrive" (Or Dropbox).

Another bar will appear at the bottom with "upload to OneDrive" (Or Dropbox). Tap that, select your file location if you wish, then you're done. I know this is an old thread, but I found it whilst trying to find an answer, so I hope this reply helps someone.

Current release of Office for Mac has added support for iCloud Drive, it's under 'more' in the list.

That function has to be built into the app by the 3rd party developer. If in the Adobe Reader app it does not give you that function then you cannot save it to the cloud.

Going by the example you give:

Download PDF file from web, or cloud service (using Dropbox here): Select the file, tap the Share icon (square box with up-facing arrow), tap "Open In...", tap "Open in Adobe Reader"

The Adobe Reader app will open and display the file as you'd expect.

To save the opened file within Adobe Reader to another cloud service, again tap the Share icon, tap "Open In...", then select the cloud service you want to save (or share) the file in.

The key is the Share icon/option. If the app does not support Sharing, you can't share/save the file elsewhere.

It is built in to MS Office for iPad, it was added last month.

Deggie is correct that it must be built into the app, and it is built in to Office for iPad

Yes, I realize that. I have MS Office for iPad. But since the OP went on to say, "But when I download, for instance, a PDF file and open it in Adobe Reader, how in the world can I save that document to a cloud account (preferably iCloud) so that I can open it in another PDF reading app?" that is why I answered the way I did and then SergZak added even more pertinent information to specific to Adobe Reader (I don't use that app).

Why use Dropbox when ICD can do the same thing?

unless you prefer DropBox?

I'll add that I do NOT have the option within Adobe Reader to save specifically to iCloud but I'm assuming it's because I don't have iCloud Drive enabled on the iPhone 5s/Apple ID that I just tested this on. I do have the ability however to share to Dropbox, Box, OneDrive, Google Drive and a couple of others.

Adobe Reader is not iCloud compatible (in terms of saving files). You can of course open PDF files in it from other sources, and save files to other apps, including apps that do connect to iCloud.

While I use iCloud Drive for a variety of apps, I have found DropBox a more useful cloud solution much of the time because it seems to offer more integration with other apps (in my case, most notably Mailbox, which can can retrieve directly from DropBox for sending attachments).

Of course, the problem can also be approached from teh other direction: there are apps for working with PDF files other than Adobe Reader, many of which may work with iCloud.

Dropbox seems to be the most widely supported online storage solution, but for me the lack of security that using DB entails is too high a price to pay, especially when there are less penetrateable systems available.

Any app can open iCloud Drive files, not all of them can save it back there.

Actually DropBox has done a pretty good job of correcting those issues in recent months (per my company's security team as well as other sources).

But it took years, and a Conressional enquiry before they stopped lying about it. I do no trust them.
