Subscribers to Adobe Acrobat Premium or Adobe Acrobat Pro DC can combine up to 12 files into a single PDF. You can also combine files from any integrated file location such as Dropbox and Drive.

Sometimes working with smaller file sizes is easier and faster–operations on large files can take longer and/or consume more bandwidth. Premium users can compress files to reduce their size. Files must not have been previously compressed.
To compress a file:
Tap ** @gt; Compress PDF**.
Optional. After compression completes, tap Open to open the file.
After compression, the file is save backed to original location; for example, to the device, Adobe Document Cloud, Google Drive, etc.
File compression is only available for files which have not already been compressed in any app (including desktop Acrobat). Attempting compression on a file which has already been compressed results in an error.
