Creating Accessible PDFs
PDFs that are created from an electronic source are already well on their way to being accessible, but some tweaks on the resulting PDF are needed. The most common method is to convert a universally designed Word Document to PDF using the Adobe Acrobat plugin.
Following are the most important steps you can take to make your converted PDFs more usable.
If you prefer to use a downloadable, printable version, guides for both Acrobat X and Acrobat XI are available in Word and PDF format below. The instructions on this page are for Acrobat X only.

Using the Acrobat Plugin
Most importantly, follow the Universal Design tips for Word Documents before conversion, including using styles for headings. Many of the actions you take to make a Word document accessible will translate over into your PDF.
- In the Acrobat toolbar, enable a setting in the Preferences menu:
- Check the box for "Accessibility and Reflow with tagged Adobe PDF" under the Settings tab (if it is not already checked).
- Use either the "Save As Adobe PDF" option in the "File" menu...
Or the "Create PDF" option on the Acrobat toolbar.
Following these steps will help to ensure that the structure of your Word document will carry over into the new format, making the PDF easier to navigate without you having to do the work twice.
Pitfalls to Avoid
Avoid using the Adobe PDF option found in your printers list. If you "Print to PDF," all the accessible formatting you just did in Word will be lost!
Cleanup After Conversion
Set the Document Language
Screen readers look at the document properties to determine the pronunciation they should use while reading the document.
In order to set the language of your pdf:
- Click on File > Properties.
- In the Advanced Tab of the Properties window, use the Language Drop-down Menu to select the language.
Set the Tab Order
The Tab Order is the order in which a keyboard user will go through the information on the page. The tab order does not always make sense compared to the way you read a document visually, so you need to specify that it should match the document structure (which we will also be checking in a moment).
- In the Page Thumbnails navigation pane on the left side of the document, select all pages.
- Click on the navigation pane dropdown menu.
- Select "Page Properties"
- On the "Tab Order" tab, select the "Use Document Structure" option:
Check the Reading Order
During PDF creation, the reading order is often mixed up and needs to be corrected. This usually happens with images, which for some reason all end up at the end instead of dispersed throughout the text.
To check the reading order, first open the Accessibility Toolbar by clicking on View > Tools > Accessibility:
This opens a toolbar on the right side of the screen, giving you several options for tweaking accessibility within the document. Select TouchUp Reading Order.
Your page should now have some numbers on it. These are the 'Tags' that determine the reading order. If the order is incorrect, select "Show Order Panel" on the TouchUp Reading Order window:
The Panel will show up on the left side of the document, where you can drag the items into the correct order.
Run the Accessibility Checker
In the Accessibility Toolbar, click on Full Check and accept the default settings in the window that pops up.
The report will display on the left side of the document where the table of contents is normally shown. The report may include issues not discussed on this page. See the links below if you are ready to go further.
