We make your PDF PDF/UA compliant.

What is an Accessible PDF?
Today, it is very crucial for your content to reach every type of audience. An accessible PDF is a document that follows standards that increases its readability. This makes content usage easier for people with disabilities and individuals using screen reader software.
A PDF is considered accessible if meets certain technical criteria such as proper heading structure, hyperlinks, alt text for images, appropriate colors, correct fonts, easy table navigation, lists, and transcript for video and audio.
What is PDF Remediation?
PDF remediation refers to the process of making a PDF document accessible. PDF remediation involves a range of techniques to ensure that the document meets the accessibility standards, such as PDF/UA or WCAG. This may include adding tags, headings, alternative text, and other elements to the PDF file, as well as ensuring that the reading order is correct.
Adding Tags to PDF
A significant part of making the PDF document accessible is to ensure the PDF is tagged. A tagged PDF includes an underlying tag tree which clearly defines the structure of the PDF document. Tags allow screen readers to read and navigate the PDF. PDFix allows you to very quickly and easily add tags to a PDF using the “Autotag” feature.
PDFix Compliance with PDF/UA
The Web Content Accessibility Guidelines (WCAG) and PDF/UA standards cover a wide range of guidance for making content accessible. PDFix supports compliance with various PDF standards, therefore making it an excellent choice for companies working with PDF documents that require standards compliance.
