Opening multiple PDFs in the same session now open the PDFs as tabs in the same application window. You can switch among the tabs from the top – tab name shows the name of the file opened in the tab. A previous button and a next button are displayed towards right to navigate through document tabs when the number of documents are high and don’t fit the document view.
Acrobat auto resizes tabs when the documents don’t fit in the view window. All the opened files are now listed towards the bottom of the Window menu. To switch to a particular opened document, either you can click the tab for the doc or choose its filename from the Window menu.
By default, the tabbed interface is ON. To enable the single document interface, clear the checkbox for the preference - Preferences > General > Open documents as new tabs in the same window (requires restart). Restart Acrobat.
To help you navigate and discover tools faster and more efficiently, Acrobat now lists tools in Tools center by categories. Tools related to similar functionalities and workflows are categorized together.
A new custom tool is displayed in the Customize category, and all third-party plug-ins are displayed in a new category named Add-ons.
When you click a filename in the recent file list, a details panel appears on the right showing a thumbnail preview of the file along with frequently used tools.
For local files, you can click the location to open the folder in Explorer. You cannot open the location if it’s Adobe Document Cloud or Dropbox.
The Remove from Recent option allows you to selectively remove files from the Recent file list.
Acrobat now supports Dropbox integration in the Home view, and allows you to easily perform standard operations on the files from within Acrobat/Reader - open, save as, create PDF, export PDF, and attach to email.
Once you add your personal or business Dropbox account, you see an entry of the same in the left pane and listing of files/folders in the right pane. Now all the actions specific to the selected file type are available for you from here, and also from a custom open/save dialog box.
- Search, sort, and filter commands are yet not available in the Home view for Dropbox files.
For more information, see Working with online accounts | Dropbox, Sharepoint.
The Combine Files tool now has a new simplified user interface. The new interface makes it easy for you to quickly combine files - add files, reorder/delete pages, preview a file, expand/collapse pages in a file, and combine them into one. You can also use the overlay tools to quickly delete pages. It now works better using touch gestures.
Hovering/clicking a file’s thumbnail shows the actions – delete the file, preview it, or expand the pages.
To collapse an expanded file, click the icon on its first page thumbnail.
For more information, see Combine or merge files into single PDF.
You can now search and select one of your recent files in a custom open dialog box. The dialog box now has the Recent option in the File List and a search box at the top.
The Recent files in the dialog box are supported only for PDFs. The files are displayed using list view. Thumbnail view and multi-file select are not supported yet.
It has now got a new look & feel, and a better reply experience.
Currently, Acrobat shows the Home screen even when no document is open. A new preference is added (Preferences > General) to switch off this behavior - Show Home screen when all documents are closed.
If you clear the preference, the Home screen is not displayed when no document is open.
New keyboard shortcuts to close Acrobat window:
- When a single document is open, press CMD+W.
- To close all Acrobat windows, press CMD+W+F4+Func.
Previously, for multiple documents, the Send for Signature feature didn't allow you to add form fields using the Prepare Form option. You had to open each document, add the fields, and then add the documents to the file list.
Now, the Prepare Form option is enabled for multiple documents. After adding the documents to the file list, if you initiate Prepare Form, the documents are converted into PDFs and combined into a single file. The combined file is opened for you to add appropriate form-specific fields. Once you are done, you can send the doc for signature.
For more information, see Send PDF documents for signature.
Because the dynamic nature of 3D provides the potential for it to be subject to security vulnerabilities, several new changes have been introduced:
- Auto-play of 3D content is disabled by default.
- The user interface has a new checkbox at Edit > Preferences > 3D & Multimedia > Enable 3D Content.
- 3D content has been integrated into the Trust Framework so that it’s possible to display 3D content for trusted content even when 3D is disabled.
For more information, see Enable 3D content in PDF.
You can now easily convert Adobe Photoshop (PSD), Adobe Illustrator (AI), and Adobe InDesign (INDD) files to PDF from within Acrobat using the Adobe Document Cloud CreatePDF service. When you choose any of these file formats for conversion, an asynchronous conversion is started and a progress bar is displayed. The file is uploaded to Document Cloud, converted into a PDF, and then the PDF is downloaded and opened in Acrobat. Meanwhile, you are free to continue working with Acrobat while the conversion is taking place.
Currently, these file formats are supported only for direct PDF conversion workflows, such as File > Create > PDF from File, Tools > Create PDF (Single File), and drag-and-drop. Also, the conversion is supported for only one file at a time. All other scenarios where PDF creation is a part of the larger workflow are not supported, such as Combine, Batch Create Multiple, Actions, etc.
Acrobat now supports AutoCAD 2015 version (64-bit). The Acrobat ribbon with PDF creation and review related features is now available for the AutoCAD version.
Acrobat now shows bulleted list and numbered list controls in the Format panel. You can now create new list items, convert an existing paragraph to a list item and vice-versa, and convert from one list type to another. Apart from the default set of list items, Acrobat now also detects addition list types in your document, if any, and shows them towards the bottom of the list pull-down menu, separated by a thin gray line.
You can also use Keyboard to add a list item. For example, before a paragraph, you can type number ‘a’ followed by the closing parenthesis ‘)’ and then add one space. It adds a numbered list starting with “a)”.
Acrobat detects paragraph and lists separately. Both paragraph and list may appear in the same bounding box while editing, however, after you save or save as the changed file and reopen it, the paragraph and list items are displayed in separate bounding boxes.
Several enhancements have been made for annotations spread across text boxes during editing:
- Highlights and other text-based annotations now work seamlessly while editing text. The annotations are bound to the text during editing, which reflows, expands or contracts, based on the editing done in and around them. If the text with the annotation is deleted, the annotation is deleted as well.
- Supported annotation types: Link, Replace text, Highlight, Underline, Strikeout, Caret, and Redact annotation.
- Page level annotations like Sticky note and typed written text can be selected, moved (by dragging), and modified.
- All the supported annotations can be deleted in editing by right-click context menu.
- If a bounding box is moved/scaled/resized, annotations are adjusted automatically. If a bounding box is deleted, annotations get deleted as well.
- You can now edit documents with outlined text (text without fonts) with high fidelity.
- The Revert to Image and the Convert to Text options in the right panel are now sticky, which means that Acrobat now remembers the option chosen by you and doesn’t default to the scanned document editing mode.

After (all the 8 pages converted as a single spreadsheet)
Allow Acrobat DC installation without removing existing Acrobat 10.x on a computer
Now Adobe Acrobat DC can co-exist with Adobe Acrobat X (10.x) upon installation. Acrobat DC installs in a different folder and does not uninstall Adobe Acrobat X.
- The components such as Adobe PDF Printer, PDFMakers (MS Office, browsers, etc.) and AcroPDF (PDFViewer in browsers) cannot co-exist due to their interaction with third-party applications. Therefore, only the latest version-specific components are available in the co-existence environment.
- Acrobat features that require a 3rd party hooks will either provide a message to the user or run using Acrobat DC hooks.
A new preference to enable PDF thumbnail previews in Windows explorer
In the April 2015 release of Acrobat/Reader DC, the PDF Shell component was removed due to which you couldn’t see the thumbnails of PDF documents in explorer. To allow you to see the thumbnails again, a new user preference is added for both Acrobat/Reader DC (32-bit machines only) -Preferences > General > Enable PDF thumbnail previews in Windows Explorer . By default, the option is OFF. Also, the preference is enterprise tunable.

What's new and changed
Improved performance and quality of OCR for Camera Images
Generally, camera images are captured at 72 DPI. Therefore, it becomes difficult to get a good quality output from running OCR on such images.
Acrobat now up-scales the resolution of the camera images while performing OCR, which results in significant increase in OCR accuracy for camera images. The time taken to perform the OCR on such images has also been reduced significantly.
Add or configure multiple signers
When sending a document to multiple signers, you can now specify their email IDs while preparing the document. It enhances the usability by allowing you to associate the desired email IDs for each signature field easily.
Add email id to a signature field
The email id is populated on the Send for Signature page
Supported file types for signing
Besides PDF, you can now send MS Office files, various image files, HTML files, and text files for signing. The list of supported file types are: DOC, DOCX, RTF, XLS, XLSX, PPT, PPTX, TXT, HTML, HTM, CSV, TIFF, TIF, BMP, GIF, JPG, JPEG, and PNG.
Sign tool available for fillable forms
The tool is now available for fillable forms in Acrobat DC and Acrobat Reader DC. When you open a fillable form, and then choose the Fill & Sign tool in the RHP or in the Tools center, you see the Signtool in the secondary toolbar.
Fill & Sign > Sign tool for a fillable form
Auto-complete email addresses
The Send & Track app now supports auto-complete of email addresses in the Send To field. The auto-complete suggestions are populated from a combination of the following:
- Local contacts: List of names and email addresses from the email messages that you have sent using the default email client.
Note: The default email client integration is currently functional only for Outlook on Windows.
- Send & Track invitations: List of email addresses from the personalized invitations that you have sent for sharing files using the Send & Track app, including the web and desktop clients.
Auto-complete email addresses in the Send To field
Resize Comments pane
When a PDF document has annotations or comments, you can now expand the Comments pane for better readability of the long comments.
To resize the pane, align your cursor along the left boundary of the pane and then hold and drag towards left or right.
Resizable comments pane
You can expand the pane only for annotations, and not for any other tool in the right pane.
Show Sticky and Highlight tools as quick tools
Acrobat DC now shows these two tools as quick tools, by default.
Tools center retains position of tools
The tools in the Tools Center remain at their position irrespective of their position or addition in the tools shortcut in the RHP.

Allow Acrobat DC installation without removing existing Acrobat 11.x on a computer
Now Adobe Acrobat DC can co-exist with Adobe Acrobat XI (11.0.12 or higher) upon installation. Acrobat DC installs in a different folder and does not uninstall Adobe Acrobat XI.
The components such as Adobe PDF Printer, PDFMakers (MS Office, browsers, etc.) and AcroPDF (PDFViewer in browsers) cannot co-exist due to their interaction with third-party applications. Therefore, only the latest version-specific components are available in the co-existence environment.
Currently, this co-existence scenario is not supported for Acrobat installation using Creative Cloud app for desktop.
HiDPI support for PDFMaker
PDFMaker now supports HiDPI displays and provides aesthetically appealing interface.
Access AATL and EUTL security settings via authenticated proxy server

Support for 64-bit TWAIN drivers on Mac
Acrobat DC now supports 64-bit TWAIN drivers on Mac OS.
- The previous version was based on the ECMAScript 3 standard. The new version is based on ECMAScript 5.
- SpiderMonkey version 24 does not support E4X, but we have retained E4X support by forward porting it from SpiderMonkey version 17. Therefore, the E4X users would be unaffected for now.Note that the E4X support may be dropped in future.
