Fixing Inaccessible PDFs Using Adobe Acrobat Pro DC
How to test: If No: This is an image file and is not accessible. If No , this document needs to be tagged. Tags provide the structure on which accessibility is built. This can also provide a fairly though not entirely accurate representation of the order in which screen readers will read the content. Study the document visually to determine what the heading structure should be.
Keep in mind that headings should form an outline of the page, as explained in the Overview of accessible documents. There are a variety of ways to explore the tag tree.
This will expand the tag tree if needed and highlight the selected tag. Then click on any tag to see the content associated with that tag highlighted in the document.
Headings should be marked up with tags that are equivalent to HTML headings tags i. Some authoring tools may create tags that have heading-like names e.
Security and signatures[ edit ] A PDF file may be encrypted for security, or digitally signed for authentication. The user password encrypts the file, while the owner password does not, instead relying on client software to respect these restrictions. An owner password can easily be removed by software, including some free online services.

Even without removing the password, most freeware or open source PDF readers ignore the permission "protections" and allow the user to print or make copy of excerpts of the text as if the document were not limited by password protection. Not only can they restrict document access but they also reliably enforce permissions in ways that the standard security handler does not. The signature is used to validate that the permissions have been granted by a bona fide granting authority.
Adobe Reader verifies that the signature uses a certificate from an Adobe-authorized certificate authority.

Any PDF application can use this same mechanism for its own purposes. Metadata[ edit ] PDF files can contain two types of metadata. This is stored in the optional Info trailer of the file. A small set of fields is defined, and can be extended with additional text values if required. This method is deprecated in PDF 2.
In PDF 1. This allows metadata to be attached to any stream in the document, such as information about embedded illustrations, as well as the whole document attaching to the document catalog , using an extensible schema.
Usage restrictions and monitoring[ edit ] PDFs may be encrypted so that a password is needed to view or edit the contents. PDF 2.

PDF files may also contain embedded DRM restrictions that provide further controls that limit copying, editing or printing. These restrictions depend on the reader software to obey them, so the security they provide is limited. Default display settings[ edit ] PDF documents can contain display settings, including the page display layout and zoom level.
Adobe Reader uses these settings to override the user's default settings when opening the document. Intellectual property[ edit ] Anyone may create applications that can read and write PDF files without having to pay royalties to Adobe Systems ; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.
Some software can automatically produce tagged PDFs, but this feature is not always enabled by default. Adding tags to older PDFs and those that are generated from scanned documents can present some challenges. One of the significant challenges with PDF accessibility is that PDF documents have three distinct views, which, depending on the document's creation, can be inconsistent with each other.
Supercharge your PDF experience.
The three views are i the physical view, ii the tags view, and iii the content view. The physical view is displayed and printed what most people consider a PDF document.They just click to open, view, comment, sign. Buy now.
For example, sharing a file through email no longer takes the file name and automatically makes it the subject line of the email.
That I can get used to but it's made it more difficult to use in my opinion. If a message appears saying that the file could not be opened in Acrobat, then that file type cannot be converted to PDF by the drag-and-drop method.
