Overview
When you create PDF documents, there are simple steps you can take to ensure that readers using assistive technologies such as screen readers can access the information in your documents. In this guide, we review important methods for incorporating accessibility in your PDFs.
Adobe Acrobat is required to create accessible PDFs
You will need access to Adobe Acrobat in order to edit PDF documents. There are two options for obtaining Acrobat access:
Adobe Reader, unlike Adobe Acrobat, is a view-only application and does not have the ability to edit accessibility information.

- Acrobat on Windows: Click Menu and select Disable new Acrobat. Acrobat will restart.
- Acrobat on Mac: Click View and select Disable new Acrobat. Acrobat will restart.

Adding autotagging
Some applications such as Microsoft Word and Adobe InDesign will automatically tag their documents when converting them to PDFs, while other applications such as Google Docs will not apply tagging.
If your PDF is untagged, use Acrobat's autotagging feature:
Quick guide
- Click the View menu. Select Show/Hide > Navigation Panes > Accessibility tags.
- The Accessibility tags pane appears in the left panel. If you see the message No tags available, you will need to autotag the PDF.
- Click the Options icon and select Autotag document.
- If you are prompted, click Not now to opt out of cloud-based tagging.
- Once tagging is complete, the Accessibility tags pane is populated.
- Save the PDF.

- Click the Options icon and select Autotag document.
- If you are prompted, click Not now to opt out of cloud-based tagging.
- Once tagging is complete, the Accessibility tags pane is populated.
- Save the PDF.
Adding alternative text to images
Images are indicated in tagged PDFs by the <figure> tag, and they require alternative text to be accessible for readers with low vision or those using screen readers.
Alt text should describe the appearance or function of an image on a page. It should be a very concise sentence or two, as the most popular screen readers will stop reading alt text aloud after 125 characters. You do not need to include “Image of” or “Photo of” in the alt text as a screen reader will announce an image. Make sure to start the sentence with a capital first letter and end it with a period.
Use the Accessibility tags pane to locate images and add alternative text:
Quick guide
- Open the Accessibility tags pane.
- Locate the first tag that is labeled <figure>. Right-click the tag and select Properties.
- If the Alternative Text for Images field is blank, fill it in.
- Click Close.
- Repeat steps 2–4 until you have added alternative text to all <figure> tags in the Accessibility tags pane.
- Save the PDF.
Detailed guide (with screenshots)

- If the Alternative Text for Images field is blank, fill it in.
- Click Close.
- Repeat steps 2–4 until you have added alternative text to all <figure> tags in the Accessibility tags pane.

Using Accessibility Full Check
