TDF Image Alt Scanner scans your entire WordPress site for images with missing or low-quality alt text and gives you a single place to fix them — across posts, pages, custom post types, the Media Library, and WooCommerce products.
Missing alt text is one of the most common and most expensive mistakes on the web:
<ul>
<li>SEO — Google uses alt text to understand image content. Missing alts hurt image search rankings and reduce the contextual relevance of your pages.</li>
<li>Accessibility — Screen readers depend on alt text. Missing alts exclude users with visual impairments from understanding your content.</li>
<li>Compliance — WCAG 2.1 / 2.2 and the European Accessibility Act both require alt text on meaningful images. UK and EU sites that ignore this face increasing legal exposure.</li>
</ul>
TDF Image Alt Scanner finds the gaps in minutes and gives you the tools to fix them.
<h4>How it works</h4>
<ol>
<li>Click Run scan. The plugin walks your posts, pages, custom post types, Media Library, and WooCommerce galleries.</li>
<li>Each image is classified as Missing, Decorative, Filename (alt text equals the file name — useless to screen readers), or Valid.</li>
<li>The Results table shows everything in one place. Edit alt text inline; mark genuinely decorative images so they’re skipped by screen readers; export everything to CSV for review.</li>
<li>Re-run the scan whenever you want to see your compliance score improve.</li>
</ol>
<h4>Free version features</h4>
<ul>
<li>Full site scan — every image on your site.</li>
<li>Compliance score dashboard with scan history.</li>
<li>Sortable, filterable bulk-edit table — filter by status, post type, or sort by date.</li>
<li>Inline edit and save per image, with “mark as decorative” toggle.</li>
<li>Detection of missing alt, decorative alt, and “alt equals filename” cases.</li>
<li>CSV export of every audit row.</li>
<li>Scans posts, pages, custom post types, Media Library, and WooCommerce products (including variations and gallery images).</li>
<li>Gutenberg-aware: handles core/image, core/cover, core/gallery, and nested blocks.</li>
</ul>
<h4>Pro features (sold separately)</h4>

<li>Per-image and bulk “Suggest with AI” actions, with review-before-save.</li>

<li>Email and Slack reports of new missing alt text.</li>
<li>Branded PDF compliance reports referencing WCAG 2.1 / 2.2.</li>
<li>Compliance score trend chart over time.</li>
<li>Page builder integrations: Elementor, Beaver Builder, Bricks, Divi.</li>
<li>Cost estimator for AI bulk jobs.</li>
</ul>
<h4>Privacy</h4>
TDF Image Alt Scanner does not send any data off your site. The plugin only uses the WordPress REST API to communicate between the dashboard and your site’s database.
If you upgrade to Pro and enable AI alt text generation, you will be entering your own API key for one of the supported AI providers. In that case, image URLs and prompts are sent directly from your site to the AI provider you’ve chosen — TDF Image Alt Scanner never sees or stores them.
<h4>Source code & building from source</h4>
The admin dashboard is a React app compiled with Vite. The unminified source is shipped inside the plugin zip at <code>admin/react/src/</code> and can be rebuilt with:
<pre><code>cd admin/react && npm install && npm run build
</code></pre>
That regenerates the bundle at <code>admin/dist/</code>. Source files: <code>admin/react/src/*.jsx</code>, <code>admin/react/src/*.js</code>, <code>admin/react/src/styles.css</code>. Build config: <code>admin/react/package.json</code>, <code>admin/react/vite.config.js</code>.

The European Accessibility Act (in force since June 2025) and WCAG 2.1 AA make 
accessibility a legal requirement, not a nice-to-have. NINJA AI Accessibility 
scans every published post and page for the barriers you can actually fix and 
scores each one 0–100, worst-first.
This is not an accessibility “overlay.” Overlay widgets don’t create 
compliance — courts have repeatedly ruled against them, and in 2025 a large 
share of accessibility lawsuits targeted sites that had one installed. We don’t 
hide problems behind a toolbar; we find the real ones in your content and tell 
you how to fix them.
What it checks (per post/page, scored 0–100):
<ul>
<li>Image alt text (WCAG 1.1.1) — flags images with no <code>alt</code> attribute. Valid 
decorative images (<code>alt=""</code>) are correctly left alone, so you don’t get 
false positives.</li>
<li>Link purpose (WCAG 2.4.4) — empty links and vague text like “click here” 
or “read more” that tell a screen-reader user nothing out of context.</li>
<li>Heading structure (WCAG 1.3.1) — skipped heading levels and multiple H1s 
that break the document outline.</li>
<li>Frame titles (WCAG 4.1.2) — embedded iframes (video, maps) with no title.</li>
<li>Table headers (WCAG 1.3.1) — data tables missing <code><th></code> header cells.</li>
</ul>
EAA readiness panel: checks for a published accessibility statement and a 
declared document language.
Honest about its limits. Some criteria — colour contrast, keyboard focus 
order, theme landmarks — depend on rendered styles and can’t be judged from 
content alone, so we never claim to. Use this to fix what’s findable and pair 
it with a manual review for full WCAG 2.1 AA / EAA conformance. The free plugin 
runs entirely on your site and makes no external requests.
<h3>NINJA AI Accessibility Pro (optional add-on)</h3>
NINJA AI Accessibility Pro (from https://ninja.si — not the WordPress.org 
directory) adds one-click, AI-assisted remediation (e.g. generating descriptive 
alt text from each image) and Accessibility Watch — it re-scans on a 
schedule and emails you when a new publish introduces a barrier or your score 
drops. Pro is the only part that contacts ninja.si, and only after you register.

NINJA AI Accessibility

Audit your content for WCAG / EU Accessibility Act issues — alt text, headings, links, frames, tables — scored with a fix list. No overlay, no fluff.
