Using Acrobat Reader app to open PDFs enables you to use advanced editing and viewing features such as sticky notes, highlights, freehand drawing, handwritten signatures, filled form data, and more. You can use Acrobat Reader app to open files from:
Apple’s Files app
Other Adobe apps such as Adobe Scan and Adobe Sign
Email and file attachments
Browsers such as Firefox, Edge, and Chrome

In workflows that ask you whether to open Acrobat just once or always, choose Always to set Acrobat as the default PDF viewer. This helps you provide broad support for the PDF standard and free PDF features such as sharing, commenting, and more.

Open from iBooks
iBooks does not offer an “Open In” or “Share” option. To transfer a PDF document from iBooks to Acrobat Reader, email the PDF document to yourself and follow the steps under Open PDFs from email.
“Copy to” vs “Open in”
Acrobat supports opening, sharing, and copying many document types to and from your device as well as other non-Adobe apps. Your file workflow may involve following menu options:
Open in Acrobat: It opens the file in Acrobat Reader app and results in both Acrobat and the source app sharing a single file. For example, when choosing “Open in” while sharing from the Files app, Acrobat uses a reference to the source file. The file is not copied to Acrobat. Any changes made to the file in Acrobat save those changes back to the original file.
Copy to: It copies the file to Acrobat’s local storage which only Acrobat may access. Changes are saved to Acrobat’s private copy and the original file remains unchanged.
Note that workflows might use both the Open In and Copy To features since Acrobat makes copied files accessible to other apps. For example, you can “Copy To” a file from Mail into Acrobat and then use the Files app to “Open In” that same file into PDF Expert. Similarly, from PDF Expert you may choose “Import From” > Choose files, and browse to Acrobat to open a file. Changes made in these external apps are saved back to Acrobat.
