PDF Accessibility Checker

The Accessibility Checker API verifies if PDF files meet the machine-verifiable requirements of PDF/UA and WCAG. It generates a report summarizing the findings of the accessibility checks. Additional human remediation may be required to ensure the reading order of elements is correct and that alternative text tags properly convey the meaning of images. The report contains links to documentation that assists in manually fixing problems using Adobe Acrobat Pro.

API Parameters

Input Document

A PDF document for which accessibility is to be checked.

Page start (pageStart)

This parameter specifies the starting page for the accessibility check. If "pageStart" is not provided, the first page is considered the default start page. It should be greater than or equal to 1.

Page end (pageEnd)

This parameter specifies the ending page for the accessibility check. If "pageEnd" is not provided, the last page is considered the default end page. It should be greater than or equal to 1.

REST API

See our public API Reference for the PDF Accessibility Checker API.
