Create Accessible Files Prior to Converting to a PDF
Before you generate a PDF, use the Accessibility Checker () to add tags and resolve any issues in the document. This is also important to do if you are not converting to a PDF and sharing the original format.
.

- In the Save As dialog box, select Options.

Adobe Acrobat Pro
Accessibility Check on Existing PDF Files
You can use the to make a PDF document accessible after it has already been generated, or if you do not have the original file. Follow the directions to navigate to the Accessibility Checker Options.
The check will produce a list of accessibility issues with a dropdown providing details and ways to make fixes.
Please note, though, that this check doesn’t differentiate between essential and non-essential issues, so they suggest that you review all issues to determine which must be resolved and which do not. You may also not be able to fix all of the issues and may be required to go back to the original file or create a new one.
Fix Issues within Acrobat
Once the checker has run, if there are any issues to resolve, you can fix (most of) them within Acrobat. First, click on the item with an issue within the list, then click on the ellipses button in the top right and choose "Fix."
If you have questions about the issue or aren’t sure how to resolve it, the ellipses menu has an "Explain" option, and when an issue is selected and this is clicked, it will open a web page with details on the issue and how to resolve it.
Missing Alt Text: Once you click on one image issue, it will allow you to cycle through any other images that are missing alt text. If the image is decorative, like a spacer line, you can mark it as decorative. Other images, like logos, photos, and charts, should have descriptive alt text.
Issues can range from missing alt text to heading issues and more. Some may not be able to be fixed within Acrobat and must be addressed in the original file.
Be sure to save the file after you have made the appropriate fixes.

Tips for Creating Accessible Content
Follow these basics when making any file:
-
Use headings for structure. These will also be tagged when you create the PDF and allow a user to navigate the file by section.聽
-
Use good color contrast. Use the to verify your colors are accessible (i.e., if you have text with a colored background).
-
Add alt text for images.
-
Use simple layouts that are easy to navigate and understand.
-
Use descriptive link text. For example, 鈥渃omprehensive 2024 sales report鈥 vs. 鈥渓earn more.鈥澛
-
Use legible fonts and font sizes.
-
Use plain, simple language. Avoid using too much jargon or acronyms.聽
-
Make sure color isn鈥檛 the only way you are conveying information.
-
Keep important information in the body of the document, vs. the header or footer.
Note: The more complex the content, the more potentially complex making it accessible will be, i.e. images of charts, complex tables, interactive elements, and more. These are a guideline and may not be applicable to all content or content types.
