4 Free Ways to Generate a Webpage Accessibility Audit Report in Chrome

You run an accessibility scan. The results appear in a browser panel. WAVE doesn’t let you export them. axe DevTools does, but only if you pay for Pro. Close the tab, and the findings are gone.

Getting those results into a format you can share with a developer or file for a compliance review requires something different. There are free tools that produce downloadable accessibility reports, but not all of them produce something usable. A CSV with raw data works for developers who know how to read it. An HTML file that opens with a promotional coupon banner doesn’t belong in a client folder. The format of the output determines whether the findings reach the people who need to act on them.

This post explores four free accessibility audit report options available in Chrome: Lighthouse, and three dedicated extensions. For each one, here’s what it exports and where it falls short.

What is a webpage accessibility audit report?

An accessibility audit report is a structured document of the accessibility issues found on a webpage. Each finding maps to a WCAG criterion and severity level, with enough detail for a developer to act on it and a stakeholder to read it.

A useful report includes:

• An accessibility score
• A full issue list with severity level, WCAG criterion, plain-language description, and affected code snippet per finding
• A best practices section covering patterns that don’t formally violate WCAG but still create barriers for screen reader and keyboard users

All automated reports cover only what can be detected programmatically. How a screen reader handles a flow, or whether keyboard navigation feels right, requires manual testing.

4 free ways to generate an accessibility report in Chrome

1. Lighthouse

Lighthouse is built into Chrome DevTools. No installation needed. Press F12, go to the Lighthouse tab, select only the Accessibility category (uncheck the rest), and click Analyse page load. Selecting Accessibility alone keeps the PDF export focused on accessibility findings only. Export the audit as JSON or HTML via the download icon, or use Print > Save as PDF.

Pros:

• An accessibility score and a list of violations with references to accessibility standards and the affected elements
• Quick to run on any page, with no setup

Cons:

• No severity breakdown. Issues are flagged but not rated according to severity
• No best practices section. Findings are limited to detectable WCAG violations
• Not formatted for handoff. The output is structured as a developer audit, not a client document

Developers find it useful as a quick signal. For client handoff or compliance filing, it’s the wrong format.

Free Chrome extensions with accessibility audit report export

Lighthouse gives you a score, not a shareable report. If the goal is a document you can hand off, that requires an extension purpose-built for accessibility. The three below all offer free report exports from Chrome. Here’s what each one actually produces.

2. Includia Accessibility Checker

Includia Accessibility Checker is a free Chrome extension that scans the page against WCAG criteria and exports a CSV. Install it from the Chrome Web Store, open the page you want to audit, click the extension icon, run the scan, and download the export.

Pros:

• All the raw data: impact level, issue title, description, CSS selector, and affected HTML for every finding
• Useful if you’re piping results into a spreadsheet or a build pipeline

Cons:

• The CSV export strips the score and summary visible in the extension UI. What you download is raw data rows only, with no aggregate context
• No formatting. A non-technical reader can’t interpret it, and it’s not suitable for a compliance review as-is

3. EqualWeb Accessibility Checker

EqualWeb is a free Chrome extension that generates an HTML report with an accessibility score, issue breakdown by severity, WCAG references, affected elements, a list of passed checks, and flags for items that need manual review. Same flow: install, open the page, scan, download.

Pros:

• A structured HTML document covering violations, incomplete checks, and passed checks
• Accessibility score, severity breakdown, WCAG references, and affected elements
• More readable than a CSV and closer to something you could share

Cons:

• The HTML format requires a browser to open and isn’t structured for direct client handoff
• Better suited to internal review than formal compliance filing or external sharing

4. Accessibility Checker by WebYes

Accessibility Checker by WebYes is a free Chrome extension built for accessibility auditing, with a dedicated PDF report designed for sharing. It runs on the rendered page in your browser, so it picks up dynamically loaded content and works on pages behind a login.

Click the extension icon and hit “Audit this page.” The scan runs in seconds against your selected WCAG criteria. Results are organised by severity. Each finding includes the WCAG criterion, conformance level, plain-language description, and the affected code snippet. A separate best practices section flags patterns that don’t technically break WCAG rules but still create real friction for screen reader and keyboard users.

Click “Download Report” to export a PDF that includes:

• Page URL, audit date, device type, and WCAG guideline
• Accessibility score out of 100 with a plain-language rating
• Full issue list: severity, WCAG criterion, description, and affected code snippet per finding
• Best practices section: recommendations beyond formal WCAG requirements

Pros:

• A clean, structured PDF formatted for direct handoff. No additional formatting needed
• Accessibility score out of 100, full issue list with severity, WCAG criterion, description, and code snippet per finding
• A best practices section covering recommendations beyond formal WCAG requirements
• Focus order visualisation, an interactive contrast fixer, heading structure inspection, disability experience simulations, and ARIA landmark mapping, all included in the same free install

Cons:

• Like all extension-based tools, it operates purely at the single-page level; testing an entire domain simultaneously requires migration to an enterprise-grade crawler solution.

How do these accessibility audit reports compare

All four options are free. Beyond that, the differences are significant.

Here’s a side-by-side comparison of all four free webpage accessibility audit report download tools:

	Lighthouse	Includia	EqualWeb	Accessibility Checker by WebYes
Report format	JSON / HTML / PDF	CSV	HTML	PDF
Accessibility score	✓	✗	✓	✓
Severity breakdown	✗	✓	✓	✓
WCAG criterion per issue	✓	✓	✓	✓
Plain-language descriptions	✓	✓	✓	✓
Affected code snippet	✓	✓	✓	✓
Ready to share with stakeholders	✗	✗	Partial	✓

The takeaway

An accessibility report is only as effective as its execution. If you need raw data to feed into a technical backlog, Lighthouse or Includia fit the bill perfectly.

However, if your primary goal is to generate a clean, professional document that can be immediately handed to a client or filed for an internal compliance review, Accessibility Checker by WebYes offers the most streamlined, distraction-free PDF export workflow of the free tools available.

Install Accessibility Checker by WebYes, free on Chrome

Scan any webpage and download the report. Share it with whoever needs it.

Frequently asked questions

Is the report export free?
Yes. The PDF report is included for free in the Accessibility Checker by WebYes extension. No account or credit card required.

Does it cover all WCAG checks?
No. It covers automated checks that can be detected programmatically. Manual testing is still required for many WCAG success criteria, including aspects of keyboard usability, screen reader experience, meaning, and cognitive accessibility.

Does the report constitute a full WCAG sign-off?
No. Automated tools cover only what can be detected programmatically. Keyboard navigation flow, screen reader behaviour, and cognitive usability require manual testing on top. The report is a thorough and reliable first layer, not a substitute for a complete manual review.

How does Accessibility Checker by WebYes extension compare to other free options?
WAVE has no export. axe DevTools has a report feature, but it requires a paid plan. Includia exports a CSV, useful for developers but not for client handoff. EqualWeb generates an HTML report, though the format is better suited to internal review than direct client sharing. Accessibility Checker by WebYes exports a clean PDF covering the score, severity, WCAG criterion, descriptions, and code snippets per issue, formatted to share directly. It also includes tools the others don’t: focus order visualisation, an interactive contrast fixer, disability simulations, ARIA landmark mapping, and desktop/mobile testing, all free.

Does it work on pages behind a login?
Yes. The extension scans whatever is currently rendered in your browser, including authenticated and locally hosted pages.

Can I scan multiple pages?
Yes, navigate to each page and run a separate scan. For full-site automated scanning, WebYes Accessibility handles that in a single run.
