The PDF Accessibility Audit: How to Evaluate Your Organization’s Document Library Before a Regulator Does

If you’re a compliance or accessibility officer, you already know the pressure is building. ADA Title II deadlines are on the horizon, Section 508 enforcement isn’t slowing down, and the volume of PDFs sitting across your organization’s servers, intranets, and public-facing websites is… a lot. The question isn’t whether your document library needs attention. It’s where to start.

The good news: you don’t have to fix everything at once. But you do need to know exactly what you have. A structured PDF accessibility audit defines the scope and puts you in the driver’s seat before an external complaint, a lawsuit, or a regulatory review forces your hand.

Here’s how to approach it.

Step 1: Take Inventory — All of It

Before you can prioritize, you need to know what exists. This sounds obvious, but most organizations don’t have a clear picture of how many PDFs they have, where they live, or who owns them.

Start by mapping your document sources:

• Public-facing website and portals — these carry the highest legal exposure and should be your first sweep
• Internal intranet or employee portals — especially relevant for Section 508-covered federal agencies and contractors
• Learning management systems — critical for higher education and employee training programs
• Shared drives and document repositories — often the “wild west” of an organization’s document library

Don’t try to manually catalog everything yourself. Work with IT to run a site crawl or repository export that pulls a list of every PDF file, its URL or file path, its file size, and when it was last modified. 

Step 2: Categorize by Risk Level

Not all PDFs carry equal risk. Once you have your inventory, sort documents into tiers based on two factors: public visibility and functional importance.

High priority — address first:

• Any PDF a member of the public must use to access services, benefits, or information (applications, forms, policy documents, legal notices)
• Documents required for legal or regulatory compliance
• High-traffic pages and downloads

Medium priority — address next:

• Frequently accessed reference documents, reports, or guides
• Documents used in customer-facing or student-facing workflows
• Anything linked from your homepage or key landing pages

Lower priority — address over time:

• Archived documents no longer in active use
• Internal-only documents with limited circulation
• Historical records unlikely to be requested

This tiering approach isn’t about ignoring lower-priority documents forever. It’s about making smart decisions with finite resources.

Step 3: Spot the Worst Offenders

Within your high-priority tier, some documents will be in worse shape than others. A quick accessibility spot-check can help you identify which ones need immediate remediation.

For each high-priority document, check for these common red flags:

• No tags at all — open the document in Adobe Acrobat and check File > Properties > Description. If the “Tagged PDF” field says “No,” the document is completely inaccessible to screen readers.
• Scanned PDFs without OCR — these are image-only files that contain no readable text. They’re invisible to assistive technology and to search engines.
• Complex tables with no header tags — tables are one of the most common accessibility failure points and one of the most confusing for screen reader users when done incorrectly.
• Images with missing or generic alt text — look for images that are unmarked as decorative or that have placeholder alt text like “image001.jpg.”
• Illogical reading order — especially common in multi-column layouts, documents created from PowerPoint, or anything with sidebars and callout boxes.

You don’t need to manually check every document at this stage; that’s what remediation tools are for. But a quick review of your highest-traffic, highest-risk documents gives you a more accurate picture of your starting point.

Step 4: Assess Your Document Pipeline

An audit isn’t just about the PDFs you already have, it also includes the ones you’re creating right now and every week going forward. Ask yourself:

• How are PDFs being created in our organization? (Word, InDesign, PowerPoint, third-party vendors?)
• Do the people creating those documents have any accessibility training?
• Is accessibility being built in at creation, or are we always remediating after the fact?

If your answer to the last question is “always after the fact,” that’s a process problem as much as a document problem. The audit is a good moment to flag this to leadership and begin a conversation about upstream changes to your document creation workflows.

Step 5: Build Your Remediation Roadmap

With your inventory, risk tiers, and spot-check results in hand, you’re ready to build a roadmap. A solid remediation roadmap includes:

• A prioritized document list with remediation status tracking
• Estimated volume by tier (number of documents and pages)
• Ownership assignments — who is responsible for remediating each document or category
• Target completion dates tied to your compliance deadlines
• A plan for ongoing documents so new PDFs don’t immediately become tomorrow’s backlog

This roadmap becomes your paper trail. If your organization ever faces a complaint or audit, the ability to demonstrate a structured, good-faith remediation effort matters — a lot.

You Don’t Have to Audit (or Remediate) Alone

If the scope of what you’ve uncovered feels overwhelming, that’s a normal reaction. Most organizations discover their PDF backlog is larger than they expected. The key is to have the right tools and processes in place to work through it efficiently.

Equidox is purpose-built for exactly this kind of challenge. Whether you’re dealing with a handful of complex, high-priority documents or thousands of files that need batch processing, Equidox’s AI-powered remediation platform helps compliance and accessibility teams work faster and more accurately than manual remediation alone, without sacrificing quality.

The regulator’s clock is ticking. Your audit is the first step toward getting ahead of it.
