Open files

You may recieve PDFs via a browser, email, or other non-Adobe apps. You can easily It’s easy to make these PDFs available in Acrobat, and you can quickly configure many apps and device features so that Acrobat is an integrated part of viewing, sharing, and reviewing workflows.

You can open a PDF in Acrobat from various applications, such as:

  • Apple’s Files app

  • Other Adobe apps such as Adobe Scan and Adobe Sign

  • Email and messaging apps

  • Outlook email attachments

  • Browsers

  • Cloud storage services like Document Cloud and Dropbox

“Copy to” vs “Open in”

To help you get your work done, Acrobat supports opening, sharing, and copying many document types to and from your device as well as other non-Adobe apps. Your file workflows may involve menu options for:

  • Open in Acrobat: The open in option is provided by your iOS) 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: Alternatively, copy to copies the file to Acrobat’s local documents cache 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.

Why use Acrobat?

Adobe recommends viewing PDFs in Acrobat Reader because other viewers (for example, Apple’s built-in PDF viewer and other PDF apps) do not display items such as sticky notes, highlight, freehand drawing, handwritten signatures, filled form data, etc. To use these cool features, simply copy the file to Acrobat.

Add Acrobat to the Share menu

The most common way to open files in Acrobat is to share PDFs (open it) from other apps via the Share menu (Tap shareicon). Sharing a file with Acrobat simply copies the file to Acrobat, and it opens automatically.

Acrobat may not appear in the app share list by default. To add Acrobat as a default item in the share list:

  1. Open a PDF in any app.

  2. Tap Open In… or the shareicon (varies by app and OS version).

  3. Swipe left until the More icon appears, and tap it.

  4. When the app list appears, tap Edit.

  5. Scroll down the app list and tap Copy to Acrobat.

  6. Tap Done to exit edit mode.

  7. Tap Done again to exit the Share settings dialog.

You should now see Acrobat as a share choice whenever you tap the Share icon from any app.


Browsers: Safari, Chrome, etc.

While different browsers may have different workflows, the most popular browsers share a common method. In both Safari and Chrome, open an online PDF Acrobat as follows:

  1. Tap the shareicon.

  2. Swipe left to show Acrobat.

  3. Tap Copy to Acrobat.



Email-to-Acrobat workflows vary across email apps; however, the two examples below describe a couple common scenarios. Note that some email apps experience known problems with many attachment types (not just PDF attachments).

  2. Tap Copy to Acrobat.

To add a custom location:

  1. In Acrobat, tap Files

  2. Tap More Locations.

When the file browser opens, you can do any of the following:

  • View a list of locations: Tap Locations. You may have the option to connect iCloud Drive from this screen.

  • Edit your locations list: Tap Locations > Edit to change your location’s list, or select a location and complete the connection workflow if required.


Files app integration

The iOS Files App (iOS 11+) allows you to easily find, organize, and manage all of your files. Available files include not only local files on your device, but also files on other iOS devices as well as cloud services such as Adobe Document Cloud. Adobe DC mobile app support for the Files app means you have greater control and ease of access for all your files and scans no matter where they reside.

AirDrop requires that you set up the target and receiving devices as described in Apple’s instructions. Devices should be on, unlocked, AirDrop-enabled, wireless and Bluetooth should be on, and so on. By default, the receiving device limits shares to people in the contacts list.

  1. Open the PDF you’d like to share.

  2. Tap shareicon > AirDrop.

  3. Choose the receiving device. If you don’t see the required device, it’s likely not set up correctly.

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 open it from your email as described above.
