PDF Remediation Tool - How to use the PDF Document and Remediation Platform (PREP)


The PDF Document and Remediation Platform (PREP) is a cloud-based PDF remediation platform that simplifies and accelerates PDF remediation to ensure accessible communications among people with disabilities using assistive technology such as screen magnifiers, screen readers, and alternative computer input devices. PREP can assist any VT employee in creating PDFs compliant with VT Policy 7215 through time-saving automation integrated within the platform.

Why Use PDF?

The creation of a Portable Document Format (PDF), was and is a step forward in making information broadly available. When creating new content, we encourage best practices and proactively design PDF documents to address the related digital accessibility challenges. We also encourage the use of alternative formats of documents, such as Microsoft Word or HTML, for increased accessibility. If the digital accessibility challenges in PDF persist, the PDF Document and Remediation Platform (PREP) can play a remediating role in making your PDF document accessible.

PREP accelerates the learning curve in making complex documents accessible by limiting the need for manual decision-making during remediation and incorporating existing approaches and best practices in accessible document design. This software will help our faculty or staff in creating accessible educational materials for use across various instructional environments. Specifically, PREP is featured with:

  • Sophisticated AI-based auto-tag detection for PDF document remediation.
  • Ability to tag nested lists and table of contents (ToC).
  • Built-in optical character recognition (OCR) mode to recognize documents with poor quality or complex structures accurately, which helps remediate scanned documents.
  • A cloud-based platform, making access available from any Mac and Windows computer or tablets with connection to the internet.
