Royal Access Accessibility Checker

Instant WCAG accessibility audit. Alt text, contrast, headings, ARIA, keyboard navigation, and more. Free, no account needed.

Royal Access Accessibility Checker gives you an instant WCAG 2.1 AA audit of any webpage — in one click, right from your browser. See critical accessibility issues, a 0–100 score, and specific fixes for each failure. No account required. No data collected. 100% free. WHAT IT CHECKS: Images • Missing alt attribute detection (critical) • Generic / filename-like alt text warnings • Alt text over 250 chars flagged as suspicious • Tracking pixels (1x1 or smaller) automatically excluded Headings • No H1 on page (critical) • Multiple H1s on a single page (warning) • Heading levels skipped (H1 → H3 without H2) • Empty heading elements Color Contrast • WCAG 2.1 AA contrast ratio checks • Critical threshold: below 2.5:1 normal text / 3.5:1 large text • Warning threshold: below 4.5:1 normal text / 3.0:1 large text • Samples up to 200 text elements per page for performance Form Labels • Form fields without accessible labels (critical) • Detects associations via for/id, aria-label, aria-labelledby, and wrapped elements ARIA • Invalid ID references in aria-labelledby, aria-describedby, aria-controls, aria-owns (critical) • Missing or multiple landmarks (warning) • role="presentation" on interactive elements (warning) Keyboard Navigation • Clickable non-interactive elements with no keyboard support (critical) • Positive tabindex values that break natural tab order Document Structure • Missing lang attribute on • Missing page title • Viewport meta that blocks user zooming (accessibility failure) Links • Links with no accessible name (critical) • Generic link text: "click here", "read more", "here" SCORING: • 0–100 score based on critical and warning counts • Logarithmic scaling — so a page with 50 critical issues scores in the 30s instead of 0, preserving meaningful distinction between bad and catastrophic pages • Traffic-light ring color: green (80+), yellow (60–79), red (below 60) • Severity label in plain language: "No issues found", "Minor Issues", "Issues Found", "Critical Issues", "Major Issues" WHY Royal Access? • One click — no setup, no configuration, no login • Zero data collection — analysis runs entirely in your browser, nothing leaves your machine • No account required — install and use immediately • Plain English — each issue has a specific fix hint, not just a WCAG code • WCAG 2.1 AA aligned — every check maps to a specific success criterion, no custom "Royal Access score" that diverges from standards • Conservative false-positive posture — when in doubt, the check reports less, not more. Tools that cry wolf get ignored. • Lightweight — Manifest V3, activeTab permission only, no background processes, no performance impact on your browsing • Clean UI — results organized into Overview, Images, Headings, Contrast, Forms, ARIA, and Links tabs WHO IT'S FOR: • WordPress and Shopify publishers wanting a pre-publish accessibility check • Freelance designers and developers auditing client sites • Agencies running accessibility triage across a portfolio of sites • Content teams verifying blog posts and landing pages before they go live • Business owners worried about ADA compliance and lawsuit risk • Accessibility professionals wanting a fast sanity check before opening a full audit tool Built by the team behind Royal Plugins — we make lightweight, privacy-respecting SEO, content, and compliance tools for the WordPress and Chrome ecosystems. For automated accessibility remediation, per-page scoring, and ongoing compliance monitoring on your own WordPress site, install the Royal Access WordPress plugin at https://royalplugins.com/royal-access/ IMPORTANT NOTE: Royal Access Accessibility Checker is an automated scanner that catches a large portion of common WCAG 2.1 AA issues but cannot replace manual testing. Some accessibility failures (meaningful alt text judgments, logical reading order, usable focus management) require human review. A green score means no automated failures were detected — not that the page is fully accessible. Privacy: this extension requests only the activeTab and scripting permissions. It runs only when you click the toolbar icon, analyzes the active page locally, and never sends page content or URLs to any external server.
