      • Pending
      • Reviewed/OK
      • Queued
      • Failed.
    • External PDFs: Select this option if the PDF file is not on your site.

      The External PDFs page opens.

    "Document remediation for compliance to WCAG 2.1 AA, Section 508, HHS or PDF/UA accessibility standards. Document remediation requires manual verification and can range in cost. When you submit PDF documents for remediation, we will review the document and give you a firm, fixed price for the remediation. Upon completion of the work, we will also provide a compliance report. We will let you know if there is any Alternative Text (Alt-Text) required for images that are not self-descriptive or any related additional information needed to remediate the document."

  3. Click OK to confirm.
  4. The remediated PDFs are sent to your email when they are finished.
  5. Remove the old PDFs from the website and upload the remediated PDFs.
