When it comes to remediating accessibility issues in PDF documents, a best practice is to make changes to the source document. So, what is a source document?

A source document is the document in its original source file type. Many people create documents in Word and convert them to PDF. The .docx file created by Word is the source document. The same goes for PowerPoint files converted to PDF. The .pptx file created by PowerPoint is the source document.

The next time you request assistance remediating accessibility issues make sure you have the source document. It will make the remediation process easier and more efficient.
