Instant Accessibility Checker

It runs 70 automated WCAG 2.1 checks covering images, links, buttons, forms, headings, contrast, page language, tables, and ARIA usage. Every failure is mapped to its success criterion and conformance level, tagged with a severity from minor to critical, and paired with corrected code generated from your own markup.

Yes, that's what the Paste HTML mode is for. Drop in markup from a staging environment, a local build, or an email template and the same 70 checks run against it. Nothing needs to be deployed or publicly reachable.

No. Automated checks catch a large share of machine-detectable problems, but keyboard behavior, screen reader flow, and the quality of your alt text still need human review. The tool says exactly this when everything passes: manual testing is still required for full WCAG conformance.

Seconds instead of minutes. The checker analyzes one document, so there's no sitemap parsing or link crawling involved. When you need results across dozens of pages, the WCAG Accessibility Scanner handles the crawl and adds exportable reports.

A check goes neutral when the page contains nothing for it to inspect. A page with no tables can't fail the table checks, and a page with no video can't fail media checks. Neutral results are listed separately so passes aren't inflated.

Each failure is rated critical, serious, moderate, or minor, and the chip next to it shows how many times it occurred. Severity is a triage signal: clear the critical and serious items first, since those block real users hardest.

Yes. This tool runs the identical 70-check engine on a single document. The scanner wraps that engine in a whole-site crawl with PDF, XLSX, and CSV exports, which is the better fit for audits and stakeholder reports.

Not through the URL mode, since the fetch happens without your login session. The workaround is simple: open the protected page in your browser, copy its HTML source, and use Paste HTML instead.

Paste a live URL or raw HTML, then press Check page or Check HTML. The website accessibility test runs all 70 automated WCAG 2.1 checks against that one document and scores it out of 100 in a couple of seconds, with the offending element and a ready-to-paste fix beside every failure.

Every check is tied to a specific WCAG 2.1 success criterion and its A or AA level, so results read as conformance findings instead of vague warnings. As a website accessibility testing tool it also groups failures by severity and shows up to five offending elements per check. It won't test SEO or broken links; it reports accessibility only.

No automated website accessibility checker catches everything. This one flags the machine-detectable subset of WCAG 2.1 issues, which is a large share, but keyboard traps, screen reader flow, and the quality of your alt text still need a person. Treat a clean score as a cue to start manual testing, not proof of full conformance.

Partly. Contrast is one of the 70 checks, so the accessibility checker flags text that fails WCAG contrast ratios and shows the failing CSS. If you want a dedicated accessibility colour checker that tests one text and background pair and suggests a passing shade, open the Color Contrast Checker. This tool catches contrast in the context of a whole page instead.
