Need to remediate a PDF for accessibility? Adobe Acrobat Pro DC offers features to help improve the accessibility of a PDF.
Do you have access to the original source document(s)? It is almost always easier to make the source document accessible before converting it to a PDF. At least, it will be a good start.
Be sure to use Adobe Acrobat Pro and not Adobe Reader. Adobe Reader does not have the tools needed to make the changes to your PDF.
Determine if your PDF is an image-only, a readable, or a tagged document.
If your document is an image-only, perform text recognition with Acrobat's optical character recognition (OCR) tool.
If your PDF has fillable form fields, add interactive form controls.
If your PDF contains linked text, add links.
Ensure the multimedia embedded or linked to your document(s) are in accessible formats.
Document tags are needed to tell screen readers and other assistive technology how to interpret the content and determine the reading order of the pages. Your document cannot be fully accessible without adding document tags. Remember, if you need to edit the content of your document during or after tagging, you may need to re-tag the document or form.
Add a descriptive document title to your file.
