PDF accessibility
Make Your PDF ADA Compliant
ADA compliance for documents means screen-reader access. Upload your PDF, see what fails, and download a tagged, machine-verified version — visually unchanged.
US web accessibility lawsuits routinely cite PDFs — menus, reports, forms, statements — that screen readers can't parse, and the DOJ's ADA Title II rule makes WCAG conformance an explicit requirement for state and local government content. What makes a PDF 'ADA compliant' in practice is the machinery of accessibility: a tag structure screen readers can walk, a declared language, a real title, alt text on images, and text that extracts as text. Ceereo audits those requirements free, then remediates the file — threading tags into your original PDF without changing a visible pixel, and re-verifying the result.

How it works
From upload to accessible PDF in four steps
The fastest way from an inaccessible PDF to a tagged, verified one — no tag panel, no service queue, no visual changes.
- Step 1
Upload your PDF
Drop in the PDF you need to make accessible. Your file is processed only to audit and remediate it, and is never used to train models.
- Step 2
The document is audited
Every PDF/UA and WCAG machine check runs: tags, reading order, language, title, alt text, font embedding and text integrity.
- Step 3
The structure is written in
Headings, paragraphs, lists, tables and figures are tagged in reading order, with headers and footers marked as artifacts to be skipped.
- Step 4
Download the accessible PDF
Get your own file back with a full tag structure, re-audited and pixel-compared so you can prove nothing visible changed.
In short
An ADA-compliant PDF is one assistive technology can actually read: tagged structure, declared language, document title, alt text, extractable text. Ceereo audits these machine checks free and produces a remediated, tagged PDF that is pixel-identical to the original, with a before/after verification report.
What makes a PDF ADA compliant?
In practice: a tag structure (headings, paragraphs, tables in reading order) that screen readers navigate, a declared document language and title, alt text on meaningful images, embedded fonts, and genuine extractable text. These map to WCAG and PDF/UA requirements referenced by ADA enforcement. Automated tools verify and fix the machine-checkable layer; complex judgment calls (nuanced reading order) may still warrant human review.
US enforcement era
The deadline math changed in 2026
ADA Title II's web rule now requires WCAG 2.1 AA for state and local government content — PDFs included — with compliance dates of April 26, 2027 (entities of 50,000+) and April 26, 2028 (smaller entities) after the DOJ's April 2026 one-year extension. Private-sector suits keep citing inaccessible documents. The affordable middle between 'ignore it' and '$3–10 per page services' is exactly what this tool is.

Why not do it by hand?
Ceereo vs. doing it manually
Remediating a PDF by hand in Acrobat's tag panel takes days and rarely verifies clean the first time. Here's the difference.
Output quality
What the remediated PDF looks like
Every run produces a tagged, machine-verified PDF that is pixel-identical to your original. Here's what you get.
- Tag tree with headings, paragraphs, figures in reading order
- Language, title, and viewer metadata repaired
- Running headers/footers marked as artifacts (skipped by readers)
- Pixel-diff verification on every page

Frequently asked questions
Does this guarantee I can't be sued?+
No tool can promise that. It makes your PDF pass automated PDF/UA checks and documents it — which removes the machine-detectable failures that complaints and scanners flag first.
Will my PDF look different?+
No — the fix inserts invisible structure only, and a pixel-level comparison verifies every page is unchanged.
What can't be fixed automatically?+
Pages that are pictures of text (scans) need OCR; interactive forms need field labeling we don't support yet. The audit tells you when your file needs those.
