A Practical Guide to PDF Remediation

For most organizations, the website is the visible part of accessibility work — but the bigger, quieter gap is the PDFs. Years of published forms, reports, and notices are often completely unusable to someone relying on a screen reader. PDF remediation fixes that.

What makes a PDF accessible

An accessible PDF isn’t just a PDF you can open — it’s one that assistive technology can navigate the way a sighted reader navigates the visual layout. That requires:

• A tag structure that defines the logical reading order.
• Properly marked headings, lists, and data tables so relationships are clear.
• Alternative text for images, charts, and figures.
• Accessible form fields — labeled and keyboard-navigable.
• Document metadata — language and title set.
• Adequate color contrast.

The relevant standard is PDF/UA (the accessible-PDF specification), aligned with WCAG 2.1 AA and Section 508.

What remediation involves

Remediation is the process of taking an existing PDF and adding the structure above. Depending on how the file was created, that ranges from light tagging to rebuilding the reading order and tables. Scanned PDFs first need OCR to become real text at all. It’s detailed work, and automated “make accessible” buttons rarely produce a genuinely conformant result — they miss reading order, meaningful alt text, and complex tables.

Prioritize by impact

You don’t have to remediate everything at once. A sensible order:

1. High-traffic, high-importance documents first — applications, notices of rights, benefits forms.
2. Documents tied to a legal deadline or obligation.
3. The long tail, over time — and fix your authoring process so new PDFs are born accessible.

Documentation

For procurement and compliance, keep a record of conformance — a VPAT or conformance report for remediated materials.
