Someone just told you your PDFs need to be “508 compliant,” and now you’re staring at a folder full of forms and reports wondering where to even start. Good news: you’re in the right place, and this is more doable than it sounds.
Here’s how to make a PDF 508 compliant, step by step, in plain English, no technical background required.
First, a 60-Second Test You Can Do Right Now
Open one of your PDFs and try two things:
- Try to highlight the text with your cursor. If you can’t select individual words, if the whole page acts like one big picture, you have a scanned PDF. To a blind person using screen-reading software, that document is completely silent. Nothing to read at all.
- Press the Tab key. If it’s a form and Tab doesn’t move you from field to field in a sensible order, keyboard users can’t fill it out.
Failed either one? That’s normal, most PDFs do. Now let’s fix it. (Want a real report instead of a finger test? Upload your PDF to our free workspace and get a full accessibility check in about a minute.)
What “508 Compliant” Actually Means
Section 508 is the federal law that says government electronic documents must work for people with disabilities. In practice, a compliant PDF is one that a person can read and use with a screen reader (software that reads the screen aloud) or with only a keyboard.
For that to work, a PDF needs invisible structure behind the visible page, things called tags. Think of tags as the braille version of your document layered underneath it: they tell assistive software “this is a heading,” “this is a table,” “read this column first.” A PDF can look perfect and still have no tags at all. That’s why so many nice-looking documents fail.
The 6 Things Every Accessible PDF Needs
- Real text, not a photo of text. Words you can select and search.
- A real title. “Water Service Application, City of Example”, not “scan_final_v2.pdf”.
- Tagged headings. So screen reader users can jump between sections the way you skim with your eyes.
- Alt text on images. A short written description of every picture, chart, and logo.
- Labeled form fields. Every blank tells the user what goes in it.
- A sensible reading order. Content announces itself top to bottom, not scrambled.
Step-by-Step: Making Your PDF Compliant
Step 1: Go back to the source file
Here’s the secret experienced remediators know: the easiest place to fix a PDF is before it becomes a PDF. If you have the original Word document, start there. Use Word’s built-in Styles for headings (Heading 1, Heading 2) instead of just making text big and bold. Add alt text to images (right-click → Edit Alt Text). Give the document a title in File → Info. Then run Word’s own checker: Review → Check Accessibility.
When you export, use “Save as PDF” with “Document structure tags” turned on, never Print to PDF. Printing to PDF throws away all the structure you just built.
Step 2: If it’s a scan, turn the picture back into text
A scanned PDF is just a photograph of paper. Before anything else, it needs OCR (text recognition), and usually re-tagging from scratch. If you have a lot of these, our guide on turning scanned PDFs into accessible documents walks through what’s involved. Honest advice: heavily scanned libraries are the number-one thing people hand off to professionals, because rebuilding them properly is slow, detailed work.
Step 3: Fix the tags in the PDF itself
For fixes inside the PDF you’ll need Adobe Acrobat Pro (the paid version, the free Reader can’t do this). The key jobs: run Acrobat’s accessibility checker to get a to-do list, fix the tag structure so headings, lists, and tables are marked correctly, set the reading order, add alt text to images, and set the document language and title. Tables and forms are the fiddly parts, header cells must be tagged as headers, and every form field needs a label and a logical tab order.
Step 4: Test like a real user
This is the step almost everyone skips, and it’s the one that matters most. Acrobat’s checker passing does not mean a human can actually use your document, automated tools catch maybe a third of real problems. (We’ve written about why automated PDF checkers miss the most important errors.) The real test: turn on a free screen reader, NVDA on Windows, or VoiceOver built into every Mac, close your eyes, and try to read the document and fill out the form. Ten minutes of this teaches you more than any checklist.
Step 5: Fix what the human test found, and re-check
Screen reader announced the table like word soup? The tags need work. Tab jumped around the form randomly? Fix the tab order. Repeat until the document actually works, then run the checker one last time and keep a record, that documentation is valuable if anyone ever questions your compliance.
DIY or Get Help? An Honest Answer
Do it yourself when: you have the original Word files, the documents are simple (letters, memos, basic reports), and someone on your team has time to learn the tools.
Get professional help when: the PDFs are scanned, they’re full of tables, forms, or charts, there are dozens or hundreds of them, or a legal deadline is involved. Complex remediation is genuinely skilled work, a single complicated form can take hours to do right.
If you go the professional route, pricing is usually per page and gets cheaper in volume. Here’s our full breakdown of what PDF remediation costs, and what our manual PDF remediation service includes. Every file is fixed by hand and verified with a real screen reader before it comes back to you.
Common Questions
Can software just make my PDF compliant automatically?
No. Auto-tagging tools produce a rough draft at best, they guess at reading order and structure, and they guess wrong on anything complex. There’s no button that replaces human judgment about what an image means or how a table should read.
Does this apply to me if I’m not a federal agency?
Quite possibly. State and local governments face nearly identical requirements under the ADA’s new Title II web rule, with deadlines in 2027 and 2028, and it explicitly covers PDFs. Here’s our plain-English guide to Title II PDF requirements.
How long does it take to remediate one PDF?
A simple text document: well under an hour once you know the tools. A long report with tables and charts: several hours. A complex form: potentially a full day. This is why page count and complexity drive cost.
How do I know if my PDF passes right now?

Start With One Document
Don’t try to fix your whole library this week. Pick your single most-used public document, the form or notice people actually download, run it through the free workspace, and fix (or send off) that one first. Momentum beats perfection.
