Equidox PDF Remediation

Making PDFs Accessible for Everyone

Use Equidox, an online PDF remediation tool, to fix and deliver accessible PDF documents for all website visitors.


Equidox is a web-based PDF remediation tool that allows you to correct inaccessible PDF documents and export an accessible PDF or HTML version. Using the various zone recognition and tagging features, you can specify headings, image descriptions, columns, tables, lists, and a logical document reading order to produce an accessible document.

Upload your PDF document and use Equidox's manual and automated settings to remediate your PDF into an accessible version. For documents that have the same visual layout and design, you can save your remediation settings to apply to multiple PDFs documents.
