Open files

We recommend that you view PDFs in Acrobat Reader because other viewers may not display items such as sticky notes, highlights, freehand drawing, handwritten signatures, filled form data, and more. You can open files in Acrobat Reader from:

  • Email and file attachments

  • Browsers such as Firefox, Edge, and Chrome

  • Cloud locations such as Dropbox, OneDrive, and Google Drive

  • Your device


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 a file from the cloud

You can use Acrobat Reader to work on files from Adobe Document Cloud or other 3rd party storage providers, such as Dropbox, Google Drive, and OneDrive. The updated PDF file automatically saves back to the original cloud location. You can pre-install these supported apps or add to your account later when required.


To access a file from Document Cloud, Dropbox, OneDrive, or Drive:

  1. Go to filesicon Files page.

  2. Tap one of the cloud storage options.

    If your account is not connected, tap Add Account and complete the workflow.

  3. Once you get access, navigate to any file and tap it to open in Acrobat. Any changes to the PDF are automatically saved back to the cloud location.

  4. Alternatively, tap Browse more files to navigate to other storage locations that are accessible on your device.
