Simplified Share experience for viewing, reviewing, and signing

The new sharing experience simplifies the way you share PDFs for viewing, reviewing, or signing. The Share interface in the right pane is now replaced with a new modal dialog box that provides you with the following four main tasks to choose from:

• Get a Link: Share a link to your PDF file for viewing or review. Next, select Allow Comments for Review to get easy and fast feedback.
  
• Invite People: Select this option to invite people to view or review PDF files by email. Next, select Allow Comments for Review to get easy and fast feedback.
  
• Attach to Email: Select this option to send a PDF file as an attachment in an email.
• Request Signatures: Send your documents for signature using Adobe Sign.

For more information, see Share and track PDFs online (New experience | Old experience).

Unified Sign tool for both signers and senders

Fill and Sign and Adobe Sign (formerly known as Send for Signature) are now consolidated into a single Sign tool where you can either fill & sign a document or get a document signed from others. It includes a simplified experience that asks you who needs to fill and sign first: you or others and then walks you through the steps to complete the task. It's the one place for all your form filling and signature needs.

1. Select Fill & Sign in the right pane or from the Tools center. The Fill & Sign interface is displayed.

2. Choose an option based on who needs to fill and sign the document/form first:

a. If you want to fill and sign the document/form, choose Me. The Fill & Sign options are displayed.

b. If you want to send the document to others for signature, choose Others. The Send for Signature Using Adobe Sign options are displayed.

Guided Fill & Sign with new share options

Acrobat now smartly recognizes that you have a form to be filled as soon as you open it for viewing – it then guides you to fill the form right there. Once you’re in the Fill and Sign interface and click Me, the fill and sign options automatically appear in the toolbar. After you complete the form and click Next, a new sharing dialog box is displayed showing the following options:

• Get a Link: Choose this option if you want to share a read-only copy of your document with others.
• Request Signatures: Choose this option if you want to send the document to others for getting their signatures.

For more information, see Send documents for signature.

Reopen PDFs from the last Acrobat/Reader session

You can now restore the previous session of open PDFs in Acrobat. When Acrobat closes unexpectedly, the Reopen Closed PDFs contextual tip is displayed. Click Restore.

Alternatively, to restore the previous session, click File > Reopen PDFs from last session.

Reopen recently closed tabs

To reopen a recently closed tab, right-click the tab of an open PDF and select Reopen Closed Tab. Select this option again to open multiple closed tabs. Alternatively, use the keyboard shortcut Alt + Shift + T. Acrobat reopens the files in the sequence they were closed.

Improved search experience

When you type the first few letters to search in a PDF, Acrobat provides suggestions for the matching word and its frequency of occurrence in the document. When you select a word, Acrobat highlights all the matching results in the PDF.

For more information, see Searching PDFs.

Contextual discovery of Acrobat tools

Acrobat now provides contextual tips based on the action performed on a PDF. These tips are intuitive and a huge time-saver. Acrobat guides you to:

• Share after you change a PDF.

• Use the Organize Pages tool after you combine files or try to use page thumbnails.
  
• Add a comment and use the Enhance Scan tool when you use the highlight tool on a scanned document. Also, in the Enhance Scan tool, when there are no scanners listed, Acrobat guides you to use Adobe Scan mobile app.

• Use the Review service if you are making comments on a PDF or working on a revised version of a document on which you have received feedback.

Commenting experience improvements

Acrobat now provides quick actions in a floating toolbar to perform contextual actions when you view a PDF. You do not have to open the commenting tool to access these actions.

• Actions on text selection: Highlight Text, Strikethrough Text, Underline Text, Edit Text & Images, and Copy Text.

• Actions on image selection: Add Sticky Note, Highlight Text, Edit Text & Images, and Copy Image.

• Actions on highlight selection: Add or Delete Note.

Improved @mention experience while reviewing documents

When you add a comment, the @mention is consistently present in the comment box for easy access and reviewer selection.

View MIP-protected files in Acrobat Reader and Acrobat on Mac desktop

Now you can use Adobe Acrobat and Acrobat Reader Mac desktop applications to open files protected with MIP (Microsoft Information Protection) solutions including Azure Information Protection (AIP) and Information Protection using Office 365.

Acrobat Reader and Acrobat now auto-detect a MIP-protected file and prompts you to download the corresponding plug-in from the help page. Once you download and install the plug-in, the protected files open like any other PDF in Acrobat or Reader.

Dropped support for Mac OS X 10.11

Acrobat no longer supports Mac OS 10.11 as Apple declared the end of support for this version in August 2018. Adobe recommends that you update your Mac OS to the latest version and install the latest version of Acrobat and continue receiving Acrobat updates.
