Best Free WordPress Accessibility Plugin: 7 Options Compared

The best free WordPress accessibility plugin for most sites is a checker, such as Accessibility Checker by Equalize Digital or Editoria11y, paired with WP Accessibility to patch common theme problems like missing skip links and focus outlines. No plugin makes a site compliant on its own. Plugins find problems or fix a few specific ones; people fix the rest and test with a keyboard and a screen reader.

Below we explain the four kinds of accessibility plugin, why none of them can promise compliance, and then compare seven plugins that are listed and maintained on wordpress.org. Every plugin fact comes from its wordpress.org page as of September 28, 2026. One of them, AtlasVoice, is our plugin. We include it only as an audio option, not as an accessibility or compliance tool.

The four kinds of WordPress accessibility plugin

"Accessibility plugin" covers tools that do very different jobs.

1. Checkers: find problems for you to fix

An accessibility checker plugin for WordPress scans your posts and pages and lists issues such as images without alt text, skipped heading levels, empty links or vague link text like "click here". Some show warnings inside the block editor as you write. They do not change your site; they catch problems while the author still remembers what the image or link was for.

2. Fixers: patch specific, known problems

Many themes ship with the same handful of gaps: no "skip to content" link, focus outlines removed for looks, links that are only identified by color, search and comment fields without labels, or a viewport that blocks zooming. Fixer plugins add or correct these in the page's code. That helps, but only for issues a plugin can safely repair everywhere.

3. Toolbars and overlays: a menu for visitors

A WordPress accessibility menu plugin adds a floating button that opens controls for text size, contrast, readable fonts, stopping animations and similar. Some products also try to repair the page automatically with JavaScript. These are usually called overlays, and they are the most debated category (more on that below).

4. Content features: extra ways to take in your content

A Listen button that reads an article aloud, a transcript for a podcast, or a plain-language summary gives people another way to use your content. They sit on top of an accessible page and do not fix barriers in it.

Why no plugin makes your site compliant

Standards such as WCAG apply to the whole site: structure, colors, forms, media, keyboard behavior and wording. Conformance means meeting every applicable success criterion, and many of them need human judgment. Software can spot missing alt text; it cannot judge whether your alt text conveys what the image is for.

Overlays get the strongest criticism. The Overlay Fact Sheet (opens in a new tab), signed by accessibility practitioners including contributors to the WCAG, ARIA and HTML specifications, concludes that no overlay can make a website fully compliant with any accessibility standard. It argues that toolbar features mostly duplicate settings that disabled users already have in their browser, operating system or assistive technology, and it urges site owners to fix problems at the source instead. Its list of overlay products includes Ally, the former name of Elementor's plugin that we compare below.

Regulators have noticed the marketing too. In January 2025 the US Federal Trade Commission announced an order requiring accessiBe to pay $1 million (opens in a new tab) to settle allegations that it misrepresented its AI tool, accessWidget, as able to make any website WCAG compliant. The FTC approved the final order (opens in a new tab) on April 22, 2025.

The better plugin authors say the same thing on their own pages. WP Accessibility states it is not intended to make a site compatible with any accessibility guidelines. Elementor says its plugin is not a substitute for a thorough accessibility audit. Editoria11y describes itself as a supplement to testing with real assistive devices, not a replacement.

The best free WordPress accessibility plugins compared

Figures are from each plugin's wordpress.org page on September 28, 2026. Ratings are the stars wordpress.org shows, with the number of reviews in brackets.

Accessibility Checker by Equalize Digital

Scans content each time you save or publish and shows issues in the editor, with more than 40 automated checks based on WCAG 2.2 and documentation for each issue. Scans run on your own server, so there are no per-page limits. The free version includes one-click fixes such as skip links, focus outlines, underlined links and labels for comment and search fields, plus an accessibility statement generator. Pro adds bulk scanning, full-site reports and more post types.

Editoria11y Accessibility Checker

Built for content authors. It highlights issues with plain-language tips on published pages and while editing in the block editor or Classic Editor. Its 50+ content tests cover alt text, link text, headings, tables, and reminders to caption videos and transcribe audio. Tests run in the browser and results are stored in your own database. The WordPress plugin was created by Princeton University's web development team; extra developer and contrast tests come with an optional "contribute what you can" supporter subscription.

Sa11y

A lightweight quality assurance assistant that runs in Preview mode and highlights over 80 checks with short tooltips explaining each fix. It is 100% free and open source, lets you switch off irrelevant checks, and supports multisite defaults. Editoria11y's core tests are co-maintained with Sa11y, so the two catch similar content issues; Editoria11y adds editor warnings and site-wide reports.

WP Accessibility by Joe Dolson

A long-running free accessibility plugin for WordPress that fixes common theme and core issues: skip links with your own targets, missing language attributes, keyboard focus outlines, labels for standard form fields, post titles on "read more" links, removing tabindex problems and re-enabling zoom. It also includes a color contrast tester, and every feature can be switched off to suit your theme.

Web Accessibility by Elementor (formerly Ally)

Combines three tools: an Accessibility Assistant that scans a URL on demand and suggests fixes (including AI suggestions), a floating usability widget for visitors, and an accessibility statement generator. It needs a connection to an Elementor account and uses a third-party service run by Elementor. Some widget features, such as white labeling and usage analytics, are in paid plans.

Accessibility Widget by OneTap

A toolbar that works without an account and offers font size, line height, contrast modes, reading line, hiding images and stopping animations, in 44 languages. Some modules and profiles, including its text-to-speech and keyboard navigation modules, are Pro features.

AtlasVoice (our plugin): audio, not a fix

AtlasVoice adds a Listen button that reads posts, pages and WooCommerce products aloud. The free version uses the voices built into each visitor's browser, with no account or API key, and can highlight the text as it is read (off by default). Pro adds AtlasVoice Cloud voices, and can use Google Cloud, OpenAI or ElevenLabs voices with your own API key, billed by that provider. Version 2.4, currently a public beta and not yet on wordpress.org, adds a free natural voice with 100,000 characters a month, saved as MP3 on your site.

To be clear about its limits: a Listen button does not fix any barrier in your page and does not make a site compliant. Screen reader users already have speech; audio mainly helps people who can read the page but prefer or benefit from listening. The Overlay Fact Sheet even counts early text-to-speech add-ons among the first overlays, so treat audio as a content feature, and test that any player's controls work with a keyboard on your theme.

Which accessibility plugin should you pick?

• You write a lot of posts and want mistakes caught early: Accessibility Checker or Editoria11y. Choose Sa11y for the lightest fully free option.

• Your theme lacks skip links, focus outlines or form labels: WP Accessibility, or the free fixes in Accessibility Checker. Pick one tool for each fix, not two doing the same job, then check the result with the keyboard. Fixing the theme itself is still the lasting solution.

• You build with Elementor and want guided fixes: Elementor's Accessibility Assistant scans pages and walks you through repairs. Judge the visitor widget separately.

• Visitors ask for text size or contrast controls: a toolbar such as OneTap can be offered as a convenience after the page itself is fixed, never instead of fixing it. Test it with a keyboard and a screen reader.

• You want an audio version of your articles: an audio player like AtlasVoice. Our guide on how to add text to speech to WordPress (opens in a new tab) walks through the free setup.

A sensible free stack: one checker, one fixer for your theme's gaps, and regular manual testing.

What accessibility plugins can't do for you

None of these can be fully automated.

• Alt text quality. A checker flags missing alt text; only a person can write alt text that says what the image is for, or mark a decorative image as decorative.

• Headings that make sense. Use H2s and H3s in order, with words that describe each section.

• Color contrast choices. Pick brand colors, button styles and text over images that keep enough contrast.

• Captions and transcripts. Videos need accurate captions and audio needs a transcript. Automatic captions need a human edit.

• Keyboard testing. Press Tab through menus, forms, pop-ups and sliders. Focus should always be visible, follow a logical order, and never get trapped.

• Screen reader testing. Try key pages with NVDA on Windows (free) or VoiceOver, built into Macs and iPhones.

• Forms and error messages. Every field needs a visible label, and errors should say what went wrong and how to fix it.

Next steps

Start with a checker on your most-visited pages, fix what it finds at the source, then do a keyboard and screen reader pass. If you sell to customers in the EU, our overview of audio articles, accessibility and the European Accessibility Act (opens in a new tab) explains where audio fits in that work. When the basics are in place and you want to offer a Listen option, AtlasVoice is free on wordpress.org (opens in a new tab).
