Hi there
Sorry for the confusion, with Acrobat’s premium subscription, you can compress a PDF file to reduce its size for easier sharing. To compress a PDF:
- Tap overflowicon > compressicon Compress PDF.
- In the compress dialog that opens, select a compression level and tap Compress in the top right corner.
It creates a compressed copy of the PDF file and saves it to Adobe cloud storage.
Note:
A file that has been compressed with ‘High compression’ level or to its smallest size cannot be compressed any further; an attempt to compress such a file gives an error message.
