December 2021 release

Acrobat introduces enhanced editing capabilities with a seamless multi-page editing experience. You no longer have to manually adjust the content to fix overlaps while editing a PDF document. The new auto-adjust layout mode in Acrobat automatically adjusts the content and reflows.

Key features:

  • Text and images adjust automatically across pages as you edit.
  • Document layout and margin are preserved while editing.
  • Navigate and select text freely across paragraphs using the cursor.
  • Make text or images inline or in front of document content.
  • Select content easily across boxes on a page.

For more information, see Edit PDFs with the new auto-adjust layout experience.


The new auto-adjust layout experience is available only for qualified English PDF documents. Adobe is testing this new experience in Acrobat. Therefore, the experience may not be available to all users.

If you compose an email and attach a PDF document, Acrobat prompts you to use the Request Signatures tool based on the PDF filename and the email subject. For example, if you use terms like form, application, and more, Acrobat recognizes these terms and prompts you to use the Request Signatures tool in Acrobat. You see one of the following prompts:

Request Signature prompt
Variant 1

Request Signature prompt
Variant 2

When you open a document that requires filling or signing, Acrobat prompts you to use the Request Signatures tool.

Similarly, when you search for files in Acrobat, the results include files shared with you, all agreements, and non PDF files saved on your Document Cloud account.
