For public documents

Accessible PDFs and the ADA Title II web rule. 6 guides, newest first.

Check what a PDF gives a screen reader

  1. Acrobat Accessibility Checker "Failed" and "Needs manual check" items: what each needs

    What Acrobat Pro's Full Check means by "Tagged content - Failed", "Figures alternate text - Failed", "Title - Failed" and four more, the fix Adobe gives, and how an item can pass while the file still fails a screen-reader user.

    Updated

  2. "Accessible version on request" or an alternate copy: does it satisfy the Title II web rule for posted PDFs?

    Mostly no. For a PDF the web rule covers, the Justice Department says neither a staffed phone line nor a statement telling people how to request an accessible copy meets the requirement.

    Updated

  3. What PDF remediation costs per page in 2026

    If you're budgeting to make posted PDFs accessible before your ADA Title II or Section 504 date, the most useful public price list is Washington State's cooperative contract for document remediation.

    Updated

  4. Which posted PDFs do you have to fix for the ADA Title II web rule?

    Some PDFs posted before your compliance date may qualify for an exception from the web rule's WCAG 2.1 AA requirements. This page walks through a way to sort your files, using the rule's own words.

    Updated

  5. PAC 2026 AI-assisted check warnings: "detected a Table element, but no corresponding structural element exists"

    PAC 2026.1 shows AI-assisted check items as warnings, not failures, and leaves them out of its PDF report. How to decide which to fix, with what we found on three public reports.

    Updated

  6. ADA Title II web rule after the April 2026 extension: your compliance date and which documents it covers

    DOJ's April 20, 2026 interim final rule moved the ADA Title II web and document deadlines to April 26, 2027 (50,000 or more) and April 26, 2028 (under 50,000 and special districts). Find your date by government type, see which posted documents the rule covers, and read the exact rule sentence next to each answer. The extension also moved the cutoff for "preexisting" documents.
