What a11yfy Actually Does
If you run a WordPress site — a university, a government contractor, a healthcare portal, anything covered by the European Accessibility Act (EAA) or ADA Title II — you probably have a graveyard of PDFs sitting in your media library: old brochures, board minutes, syllabi, tax forms, annual reports. Most of them were never built with accessibility in mind, and now regulators are starting to notice.
a11yfy is a new WordPress plugin that attacks this problem in two stages. First, it scans a PDF directly in your browser — no server round-trip, no upload — checking it against PDF/UA-1, the ISO standard for accessible PDFs, using the 42 checkpoints defined by the Matterhorn Protocol (the standard test suite most PDF/UA validators, including the well-known veraPDF, are built on). That scan is free and runs locally, which matters if you're dealing with PDFs containing sensitive data like student records or medical forms — nothing leaves your browser during the check.
Second, if the scan turns up problems — missing tags, no reading order, untagged tables, missing alt text, image-only pages with no OCR layer — you can pay to have a11yfy actually fix it. That step sends the file to EU-based servers for remediation: adding structure tags, fixing reading order, running OCR on scanned/image-only pages, and generally rebuilding the PDF so it passes PDF/UA-1 checks rather than just getting flagged.
How the Credit System Works (and What's Murky About It)
Here's the part that's less polished than the rest of the plugin: pricing isn't disclosed on the WordPress.org plugin page itself. Remediation runs on a credit system, and the plugin listing states usage is typically 1-3 credits per page, depending on how broken the PDF is — a clean, mostly-tagged PDF that just needs alt text costs less than a scanned, image-only PDF that needs full OCR and structural rebuilding. But the actual dollar cost per credit isn't published in the plugin repo; you're redirected to a11yfy.com/pricing to see current rates and buy credit packs.
For a first-look review, that's a real friction point. If you're a solo consultant or small nonprofit trying to budget for remediating, say, a 40-PDF backlog before an EAA compliance deadline, you can't get a hard number without leaving WordPress and creating an account on the marketing site. Budget-conscious teams should treat this as a required step before rolling this out past a test PDF — check current per-credit pricing on a11yfy.com before assuming costs.
Where It Actually Fits
Use case 1 — Pre-audit triage. You've got 200 PDFs on a university site and a compliance deadline. Instead of manually opening each one in Acrobat, install a11yfy, batch-scan your PDF library for free, and get a prioritized list of which files fail PDF/UA-1 and why. This alone is worth installing even if you never buy a credit.
Use case 2 — Fixing scanned government forms. Image-only PDFs (old scanned forms with no text layer) are one of the most common accessibility failures and the hardest to fix manually. a11yfy's OCR-based remediation is built for exactly this — feeding in a flat scanned form and getting back a tagged, readable, EAA-compliant PDF.
Use case 3 — Ongoing compliance for a content team. A comms team that regularly uploads new PDFs (press releases, reports) can run every new upload through the free scanner as a pre-publish check, catching accessibility regressions before they go live, and only spending credits on the files that actually fail.
Where it's a weaker fit: if you need heavy manual control over remediation — reordering tag trees by hand, fixing complex nested tables, or doing forms/interactive field remediation — you'll likely still need a dedicated desktop tool alongside it.
How It Compares
| a11yfy | Adobe Acrobat Pro | Axe PDF Accessibility Checker | PDF Accessibility Wizard | |
|---|---|---|---|---|
| Where it runs | Inside WordPress; free scan in-browser, remediation via EU servers | Desktop app (Windows/Mac) | Desktop/enterprise tool | Standalone automated remediation tool |
| Pricing model | Credit-based (1-3 credits/page for remediation); rates on a11yfy.com/pricing | Subscription, ~$19.99/mo (Acrobat Pro DC individual) | Enterprise licensing, quote-based | Per-license or batch pricing, quote-based |
| Standard checked against | PDF/UA-1, 42 Matterhorn Protocol checkpoints | PDF/UA (via built-in accessibility checker) | WCAG/PDF/UA rule sets | PDF/UA remediation focus |
| OCR for scanned PDFs | Yes, included in paid remediation | Yes, via Acrobat's OCR tool | Scanning/checking only, no OCR remediation | Yes, automated OCR remediation |
| Best for | WordPress sites with a PDF backlog needing quick triage + fixes without leaving the CMS | Teams needing full manual tagging control and broader PDF editing | Enterprises needing rigorous automated compliance auditing at scale | Batch remediation outside a CMS workflow |
| No-install trial | Free scan, no account needed for scanning | 7-day free trial | Demo/trial via sales contact | Varies by vendor |
The Honest Verdict
a11yfy's smartest move is doing the free scan entirely client-side and putting it inside WordPress, where your PDFs already live — you're not exporting files to a third-party dashboard just to find out if they're broken. That alone makes it worth installing today if you manage any PDF library on WordPress and haven't run a PDF/UA audit before.
The remediation side is promising — EU-based processing plus OCR for image-only files covers the two hardest, most common failure modes (untagged structure and no text layer). But the opacity around per-credit pricing on the plugin page itself is a real gap for a first release. Before you commit budget to fixing more than a handful of files, go price out credits on a11yfy.com directly, and test the free scanner against a few of your worst PDFs first to see how many credits a typical fix will realistically cost you.
