Sharing & reviewing

Acrobat Reader’s supports sharing, tracking, and managing file shares whether read-only or sent for a collaborative review. Review service subscribers can easily enable team collaboration and collect feedback on any file. Highlights include:

  • Sharing view-only files (free) or sharing files for review (subscription) so that recipients can comment and markup files
  • A Share user interface and feature set that’s similar across the desktop, web, and mobile devices
  • Always synchronized files across any connected device
  • Easy controls for creating, participating in, and managing reviews
  • Real-time notifications of file views, changes, and participation as well as support for @mention tags
  • Pan, zoom, or scroll while in commenting mode.

Share and Review tags

You can easily determine a file’s share status since the app’s file lists indicate whether a file is simply Shared (view-only) or in Review. For example, when you search for a file, the search result displays the share tag as either SHARED or REVIEW. You can also use the Share view’s share tabs to determine what files are view-only or in review.


Share and Review tabs

When no document is open, you can view all your shared files from the Shared view.

  1. Tap image to view your shared files.

  2. Tap either For Viewing or For Review tabs to see your separate file lists.


    Both tabs list files grouped by Shared with you and Shared by you.


Initiating a share or review

Sharing a file is easy, and you can track and manage the share from your mobile device, the desktop, and the web. You’ll receive push notifications when reviewers participate.

  1. Open a PDF. If the top menu is not visible, tap the document.
  2. Tap image
  3. Add 1 or more email addresses.
  4. Optional: Tap the subject line and/or message text box to edit them.
  5. If you’re sending the file for review, enable Allow comments for review. View files are read-only. Review files allow recipients to add comments and annotations.
  6. For reviews, you can set a deadline: Tap image > Set Deadline. Set your date and tap OK.
  7. Choose Send.

The file automatically uploads to Document Cloud. Document recipients can access the file from the web as well as their desktop or phone. Alternatively, you can share a link to the file or a copy of the file.


Share options also include sharing a copy of a file or sharing a link to the file.

  • Sharing a link saves bandwidth and provides access to files stored in the cloud.
  • Sharing a file copy may save users time and provides alternate ways to deliver the file. For example, you can send a file as an email attachment.

To do so, use the Share method described above, and tap Create Link or Share a Copy.


If you don’t enter any email addresses prior to choosing Create Link or Share a Copy, the app invokes your app list. You can then email the file, save a copy to Google Drive, or share the file with any supported app you’ve installed.


Reviewing files

The review feature allows you to add comments and annotations, edit comments, reply to comments, and receive notifications when there is activity on your thread comments.

  1. When you receive a review invitation email, click the link. Clicking on a link in 3rd party mobile apps automatically opens the Acrobat Reader in the review.

  2. Sign In with your Adobe ID. The advantage of signing in is that you can edit or delete your comments at any time, including future sessions.

  3. Choose Join Review.

  4. Add, reply to, and delete comments as usual.

  5. The document is automatically saved, and all reviewers will see your comments.


    Using the image tag sends a push notification to the named reviewer. The app also sends notifications whenever a comment or annotation is added or changed.

There are two types of notifications: Requests and simple messages. Requests are like action items–these may be direct messages, requests to review a file, and so on.


Notifications include deadlines, reminders, real-time messages from the sender, and other messages. Depending on what you’ve permitted, notifications may also appear on your device’s home screen.


Managing reviews

While you will receive a notification email when reviewers view and comment on your file, you can actively monitor and track reviews online or from the desktop.
