Adobe Reader for iOS can open and view PDF files from email, on the Web or from any application that supports the “Open In” function. This means you can easily use just about any cloud storage service that has an iOS app to sync your PDF files on your iPhone or iPad. If you’d rather transfer files to your device, that’s pretty easy too; just use iTunes. One thing to be aware of is that Spotlight is not yet able to search inside PDF files at this time so you’ll want rename your files to something meaningful prior to transferring them.
Transferring PDF files to iOS Devices:
- Open iTunes and plug in your iOS device.
- In the devices Synch panel, select Apps.
- Under “File Sharing”, select Adobe Reader
- Drag your file(s) into the “Adobe Reader Documents” area
- Sync your device
Your files will now show up in the Adobe Reader “Documents” window.



This is great but this doesn’t work for a PDF folder.
I often have numerous related pdf docs neatly stored in relevant folders but can’t seem to add the folder, only single docs.
For folders, you definitely want to use a cloud based service. I use Dropbox and I love it for this sort of thing but any application that supports the “Open In” function on iOS will work.
