Make a PDF Accessible

Printer-friendly Instructions

HTML pages achieve accessibility better and more consistently than PDF files and should always be your first choice whenever possible. The most common reasons to use PDFs are to:

  • Publish secure printable documents that cannot be altered or copied
  • Preserve the formatting of documents for printing

If you must publish a PDF to the website, it must still legally meet all of the same accessibility requirements as an HTML web page. That means content, heading structure and image alt tags must all be part or your PDF document.

Below are ways to improve PDF accessibility using Adobe Acrobat Pro DC.  Also refer to the webinar listed under Accessibility links.

Steps to remediate a PDF file using Adobe Acrobat Pro DC

Add a Descriptive Title

File > Properties > Description Tab > Title

In the Dcoument Title window add a descriptive Title

File > Properties > Initial View > Windows Options > Show Dropdown > Document Title

Click the Accessibility tool in the Tools Bar

If you do not see Accessibility in your Tools bar, click More Tools, find Accessibility and in the dropdown, click Add Shortcut.

Select the Accessibility tool from right hand menu in Acrobat

Set alt tags to images and figures

A pop-up box will appear and highlight each image that you need to set an alt tag for. Describe the image in as few words as possible but still get the purpose of the image across. Text inside images is highly discouraged because it is inaccessible, but if there is text inside of an image, the alt text field is the best place to add it. If the image is not essential to the information being presented, add a space and click "decorative image."

in Accessibility Tool mneu, select alt text and cycle through all images in the set alt text window and add descriptive text

Click “Autotag Document”

This will search and tag headers, paragraphs, images if you have them in your document. If the document is already tagged, click "No."

In the accessibility Tool menu, click the autotag button

Run Full Check

In the Accessibility Tool menu, select the Full check button and then start check in the window that appears

Running a full check may reveal additional errors. Often they will be related to page structure in your original document. If possible, make the original document more accessible by using headers where you can.

The check will create a left side window of completion or additional errors.

Save your document.
