Accessible PDF files are the ones that can be read using assistive software/hardware. In other words, files or documents that can be easily accessed by people with different-abilities are known as accessible PDF files. These documents have to meet the standard accessibility standard criteria such as ADA, DDA, Section 508 compliance, WCAG 2.0 & 2.1 guidelines, etc. The PDF files are made accessible by adding tags to various elements of the document such as title, prologue, epilogue, conclusion, and so on. These labels help the assistive technologies in finding the order in which it has to be read. However, remediating such files without missing the author’s intent of conveying is an uphill task. Plus there are no tools to check whether the documents are completely accessible or not. In such a scenario, collaborating with an outsourcing vendor is an intelligent option.
