Your website’s accessibility doesn’t stop at your pages: every PDF you publish is part of your compliance. EqualWeb Accessibility finds every PDF on your site and puts a complete accessibility workflow next to each file, a free PDF/UA checker with scores and shareable reports and AI-powered remediation that returns a tagged, fully accessible PDF. It also carries the EqualWeb accessibility widget your visitors use on every page, with the button designed from WordPress.

Up to 100 MB and 200 pages per document
The original structure, layout and visual design are preserved exactly

Automatic classification and triage by where each PDF is used
Light and dark theme, English UI, accessible design
Accessibility widget
Paste the installation code from your EqualWeb account once; the plugin loads the widget on every page the right way (deferred, with its integrity hash), never as raw code
Design the accessibility button from WordPress: side, vertical position, size, colours, icon (14 icons or a short text), shape and outline, with a live preview of the real widget and a contrast readout
Menu language: automatic (the page language) or any of the widget’s languages
Use your own button if you prefer: a shortcode places an accessible button that opens the EqualWeb menu
“Check on your site” confirms the widget really is on your pages
Hide the widget from logged-in administrators while you edit
Pricing
The widget comes with your EqualWeb plan. PDF checking is free forever. Remediation uses credits – about 1 credit per page, a one-time payment per document, with no ongoing fees. Volume pricing starts at $2.50 per page and drops to $1.00 per page at higher volumes.
Upgrading from version 1.x
Version 1.x of this plugin only embedded the widget code. Your installation code and on/off setting are imported on the first visit to the plugin page after the update; the widget keeps working with no action needed, and you can now design the button from the Accessibility Widget tab. The old settings page address opens the new tab.
External services
This plugin connects to EqualWeb services. Nothing is sent to anyone else.
When the widget is turned on, every public page of your site loads the widget script from EqualWeb’s content delivery network (cdn.equalweb.com, the exact core version and integrity hash named in your installation code) in the visitor’s browser, with your EqualWeb site key. The script then contacts EqualWeb’s widget service (access.equalweb.com) for the menu, its styles and usage statistics for your site, as described in EqualWeb’s privacy policy. No personal data is sent by this plugin itself; the browser requests carry what any script request carries (the visitor’s IP address, user agent and the page address). The plugin’s “Check on your site” fetches your own front page from your server and reads the widget’s language list from cdn.equalweb.com (cached for a day).
Free PDF checks run through this service, which holds EqualWeb’s key for the free checker so that your site needs no account. These calls are made by the web server, from the plugin’s admin screen, never from the public pages of your site.
Site registration, once per site, before the first free check. What is sent: your site address (the Site Address in Settings > General), the address of the plugin’s verification page (/wp-json/eqw/v1/verify), a one-time code, the platform name (“wordpress”), the plugin edition (“wp”), the plugin version, the WordPress version and what started the registration (“page”, “button”, “check” or “host_change”). The service then fetches the verification page once, from the internet, to confirm that the site runs this plugin, and answers with a site token that the plugin stores in the database. When: automatically after an administrator opens one of the PDF tabs of the plugin page (retried on a schedule while it fails: after 10 minutes, 1 hour, 6 hours, then daily), when an administrator clicks “Try again”, before the first check on a site that is not registered yet, and before a check after the site address has changed. Registration never runs on activation, never from the Accessibility Widget tab, and never for visitors.
Free checks. What is sent: the PDF file you check, with the site token. When: when you run a free check on a file (this includes the bulk check action), and while the plugin polls for the result.
With every request to this service: the site’s host name, the platform name, a tenant identifier (the host name, prefixed by the blog id on a multisite network) and the plugin version, in the request headers X-Eqw-Site, X-Eqw-Platform, X-Eqw-Tenant and X-Eqw-Plugin, so that usage can be attributed to this installation.
Failure diagnostics: when a registration fails, the service keeps a diagnostic record for 30 days: the failure reason, what the verification page answered (HTTP status, redirect target, page title, server and cache headers), the plugin and WordPress versions, what started the attempt, and the name, number and country of the network the request came from (its autonomous system). The IP address itself, the one-time code and the site token are not stored in that record.
EqualWeb API (login.equalweb.com)
AI remediation is optional and requires an EqualWeb account and credits.
What is sent: the document you choose to remediate, authenticated with your EqualWeb API key, together with the attribution headers listed above. The key is stored encrypted, used only in server-side requests, and never exposed to site visitors.
When: when you start a remediation, when you save an API key (the key is validated before it is stored), when the Settings tab opens with a key saved (to show the credit balance), and for free checks on a site with a saved API key (those run on your account instead of the check proxy). “View report” links open report pages on this host in your browser.
Service provider: EqualWeb.

Frequently asked questions.
Do I need an EqualWeb account for the widget?
Yes. The widget belongs to your EqualWeb account, where you register your website and get its installation code. Create an account at login.equalweb.com.
EqualWeb told me to update the widget code. What do I do?
Copy the new installation code from your EqualWeb account and paste it in the Accessibility Widget tab. Every core version comes with a new code and integrity hash, for security; the plugin never changes the version on its own.
Can I use my own accessibility button?
Yes. Turn on “Use my own button” in the widget options and place the shortcode [equalweb_button text="Accessibility"] where the button should appear. Your theme styles it; EqualWeb opens the menu from it.
I updated from version 1.x. Where did my settings go?
They were imported: the Accessibility Widget tab shows your site key and the widget stays on. If your old code could not be read, it is kept as it was and the tab asks you to paste the current code from your EqualWeb account.
Is the PDF checker really free?
Yes. Scanning and full reports are free and require no account. Only remediation uses EqualWeb credits (about one credit per page).
What file types can I remediate?
PDF (including scanned PDFs), Word, PowerPoint and Excel. Whatever you send, the result is a tagged, accessible PDF.
What are the size limits?
Up to 100 MB per file and up to 200 pages per document.
Which standards are files checked against?
PDF/UA (ISO 14289), aligned with WCAG 2.2, Section 508, the ADA and EN 301 549.
Will links to my PDFs break when I replace a file?
No. “Replace original” keeps the same URL, so existing links serve the accessible version. A backup is kept and can be restored anytime.
Where is my API key stored?
Encrypted in your site’s database, used only in server-side requests. It is never printed in HTML or exposed to visitors.
Where are my documents processed?
In EqualWeb’s secured cloud, which is certified to ISO 27001.
Free checks are “not set up” on my site. What now?
The plugin page explains the reason and what to do. Free checks need a site that is reachable from the internet over https://, whose verification page (/wp-json/eqw/v1/verify) answers anonymous requests directly: not behind a login, a redirect, a firewall rule or a page cache. Fix the cause, then click “Try again”. The “Technical details” block holds what EqualWeb support needs.
