Follow the prompts to complete the Make Accessible action. The Accessibility toolset is displayed in the secondary toolbar. The Accessibility Checker Options dialog box is displayed. Select a page range if you prefer to check individual pages of a document. Select one or more of the Checking Options.

The report displays one of the following statuses for each rule check: Passed : The item is accessible. Verify the item manually. Failed : The item didn’t pass the accessibility check. Use Read Out Loud to experience the document as readers who use the text-to-speech conversion tool experience it. Save the document as accessible text and then read the saved text file in a word-processing application.

This exercise enables you to emulate the end-user experience of readers who use a braille printer to read the document. Fix accessibility issues Acrobat Pro.

Skip Rule:. Runs the checker again on all items. Choose this option after modifying one or more items. Displays a report with links to tips on how to repair failed checks. Accessibility issues. Prevent security settings from interfering with screen readers. Or, fix accessibility permissions manually:. Image-only PDF. The Scan toolset is displayed in the secondary toolbar. Tagged PDF. If this rule check fails, the document isn’t tagged to specify the correct reading order.

To specify tags manually, do one of the following: Enable tagging in the application in which the PDF was authored, and re-create the PDF. The Add Tags Report appears in the navigation pane if there are any issues. The report lists potential problems by page, provides a navigational link to each problem, and provides suggestions for fixing them.

For more information, see Reading Order tool overview. Open the Tags panel and create the tags tree manually. For more information, see Edit document structure with the Content and Tags panel. Logical reading order. Document language. If the language doesn’t appear in the drop-down list, you can enter the ISO code for the language in the Language field.

This setting applies the primary language for the entire PDF. Set the language for all text in a subtree of the tags tree. Open the Tags panel. Expand the Tags root and select an element. Then choose Properties from the Options menu.

PDFs can conform with this provision in several ways, including outlines 7. G G G Not addressed in ISO No Accessibility Support impact. Then, it builds a tag tree that reflects that information. It also creates tags for any links, cross-references, and bookmarks that you added to the document in Acrobat. The Add Tags To Document command adequately tags most standard layouts. However, it cannot always correctly interpret the structure and reading order of complex page elements.

Tagging these pages by using the Add Tags To Document command can result in improperly combined elements or out-of-sequence tags. These issues cause reading order problems in the PDF. You can add a watermark to a tagged PDF without adding it to the tag tree. Once you have a tagged PDF, evaluate the document for reading order problems, tagging errors, and accessibility errors, and then repair them as needed.

Whichever method you use to tag the PDF, use Acrobat to touch up the tagging and reading order for complex page layouts or unusual page elements. It may incorrectly tag all of these elements as figures. Similarly, this command may erroneously tag graphical characters within text , such as drop caps, as figures instead of including them in the tag that represents the text block.

Such errors can clutter the tag tree and complicate the reading order that assistive technology relies on. If you tag a document from within Acrobat, the application generates an error report after it completes the tagging process.

Use this report as a guide to repair tagging problems. For example, if the web page relies on tables for its layout design, the HTML code for the table may not flow in the same logical reading order as a tagged PDF would require, even though the HTML code is sufficiently structured to display all the elements correctly in a browser.

Depending on the complexity of the web page, you can do extensive repairs in Acrobat Pro by using the Reading Order tool or editing the tag tree in Acrobat. For more information, see the guidelines on the W3C website.

Creating tags in the authoring application generally provides better results than adding tags in Acrobat. For more information about creating accessible PDFs, see www. You can combine multiple files from different applications in one operation to create a single PDF. For example, you can combine word-processing files with slide presentations, spreadsheets, and web pages. If you start with a mix of tagged and untagged PDFs, tag the untagged files before proceeding.

When you insert, replace, or delete pages, Acrobat accepts existing tags into the tag tree of the consolidated PDF in the following manner:. When you insert pages into a PDF, Acrobat adds the tags if any for the new pages to the end of the tag tree. This order occurs even if you insert the new pages at the beginning or the middle of the document. When you replace pages in a PDF, Acrobat adds the tags if any from the incoming pages to the end of the tag tree.

This order occurs even if you replace pages at the beginning or the middle of the document. Acrobat retains the tags if any for the replaced pages. Pages whose tags are out of order in the logical structure tree can cause problems for screen readers.

Screen readers read tags in sequence down the tree, and possibly do not reach the tags for an inserted page until the end of the tree. To fix this problem, use Acrobat Pro to rearrange the tag tree. Place large groups of tags in the same reading order as the pages themselves. To avoid this step, plan on inserting pages to the end of a PDF, building the document from front to back in sequence.

This approach places the tags for the content after the tags for the title page. Essentially, they are large pieces of empty tag tree sections. These redundant tags increase the file size of the document, slow down screen readers, and can cause screen readers to give confusing results.

For best results, make tagging the last step in the conversion process. Use Acrobat Pro to delete the tags of deleted pages from the tag tree. For more information, see Create merged PDFs. Acrobat Pro, Acrobat Standard. Use one of these applications to open untagged or tagged PDF forms except PDF forms that are created from Adobe Designer to add fillable form fields, such as text boxes, check boxes, and buttons. Add descriptions to form fields, tag untagged forms, set the set tab order, manipulate tags, and perform the other PDF accessibility tasks.

Authoring applications. Use the forms tools in Acrobat Pro to add fillable form fields. Moreover, if you tag the form during conversion to PDF, the authoring application can generate inappropriate tags for the text labels of the form fields. In a complex form, for example, the text labels for all the fields can run together into a single line. Such reading order problems can require time-consuming work in Acrobat Pro to split the labels apart. In this case, producing an untagged PDF form from the authoring application is sometimes the better course.

You can then use the Forms tools in Acrobat Pro to add fillable form fields before you tag the entire document. Some forms are straightforward enough that you can produce a tagged PDF from the authoring application. Then perform light touch-up in Acrobat Pro after you add the fillable form fields. Forms tend to have relatively complex layouts compared to documents that have a simple, single-column structure.

The success that an application has in analyzing and tagging a form depends largely on the original formatting and layout of a document, and the types of fields that it uses. When you design a form, include headings, instructions, and fields in which users are to enter data. At a minimum, give each field a label. Also add special instructions for fields that need them.

Use graphics tools to draw lines and boxes.
