Top new features and changes in October 2019 release of Acrobat DC
Acrobat DC

Acrobat DC with Adobe Document Cloud services is the complete PDF solution for working with your most important documents across desktop, web, and mobile devices. Get the latest Acrobat update – on the Help menu, click Check for updates and follow the onscreen instructions to complete the update process.

Star your important files and access them across devices

You can now star your important files in Acrobat to access them later from any device. You can star files from your local machine, in Document Cloud, or any third-party storage. You can’t star files that you sent or received for signing.

On starring, local files are copied to Document Cloud. Third-party storage files are not copied to the cloud. You can find all your starred files from the Starred tab in the Home view. A filled star icon in Recent indicates that the file is starred. When you unstar a file, the file is removed from the Starred tab but is retained in the cloud.

Starred tab in Home view

Star a file from Home or Viewer:

  • In the Home view, hover the cursor on the PDF file, and click the Star icon next to the filename.
Star a file from Recent
  • Open the PDF file in Acrobat DC and click the Star icon in the toolbar.
Star a file from the Viewer

When you star a PDF file for the first time, you are prompted to select if you want to access the starred files on all your devices or on a particular device.

Starring a file for the first time

You can change the preference anytime by going to Edit > Preferences > Adobe Online Services.

Simplified 1-click compress PDF experience

Now you have a single-click option to generate an optimized version of a PDF file directly from the File menu in Acrobat. After you have edited a PDF document, compress the size of the file by choosing File > Compress PDF or Reduce File Size.

Unified edit text and form fields experience

Easily create forms that require multiple signers

When you send documents for signature from Acrobat through Adobe Sign, you need to place form fields on the document and mark where signers need to fill in data and sign. In the previous release, we introduced a simple version for placing these form fields for a single signer. In this release, we are extending the simple version with the capability of assigning fields to multiple signers.

When you select a signer from the right pane, all fields created are assigned to the selected signer.

Simplified mode for multiple signers

You can switch the assignee of any field using the floating toolbar. The assigned colors to the signers make it easy to distinguish the fields for respective signers.
