Free website accessibility checker
Can everyone use your website? This free WCAG checker runs WCAG 2.2 tests on your page in a real browser: the axe-core rules plus tests that use the page with a keyboard. Every barrier in plain words, with who it affects and the fix.
WCAG 2.2, axe-core plus keyboard testsAbout a minuteNo sign-up
What it checks
Barriers the tests find
Text contrast
Text that doesn’t stand out from its background (pale or bright colours on light ones), measured from the page (1.4.3).
Labels and names
Fields, buttons and links that screen readers can’t name (1.3.1, 4.1.2, 2.5.3).
Keyboard use
Tabbing through the page: invisible focus, traps, focus hidden behind a sticky bar (2.1.1, 2.1.2, 2.4.7, 2.4.11).
Headings and links
Fake and empty headings, and links that say only “click here” (1.3.1, 2.4.4, 2.4.6).
Text spacing and zoom
Text that gets cut off when people widen line spacing or enlarge text (1.4.4, 1.4.12).
Forms
Fields without labels, missing autocomplete on personal details, and paste blocked on passwords (1.3.5, 3.3.8).
Three steps, about a minute
- 1
Paste your page
Any public address: a live page, a staging link or a client preview.
- 2
We test it like a person would
The WCAG rules run in Chrome, then the page is used with a keyboard, with spacing and text size changed.
- 3
Fix what blocks people
Each barrier with the WCAG criterion, who it stops and how to fix it.
Guide
What an automatic accessibility check can and can’t tell you
- 01
What it catches
Machines are good at measurable rules: contrast ratios, missing labels and names, heading structure, focus you can see, and pages that fall apart when text gets bigger. These are also the most common barriers on real sites. - 02
What still needs a person
No tool can judge whether alt text describes the picture well, whether the reading order makes sense or whether instructions are clear. UICheck marks each WCAG 2.2 criterion as tested, partly tested or for a person to check, and never claims a page conforms. - 03
The fixes that help most
Darken faint text to at least 4.5:1 (3:1 for large text), give every field a visible<label>, keep a visible focus outline (:focus-visible), use real<button>and<a>elements, and use headings in order. The Color Contrast Checker finds the nearest colour that passes. - 04
Why it matters
About one in six people lives with a disability, and laws such as the ADA, the European Accessibility Act (in force since June 2025) and the UK Equality Act expect websites to be usable by them. Accessible pages are also easier for everyone to use.

Questions
Which standard does it test?
WCAG 2.2 at levels A and AA, using axe-core’s rules plus UICheck’s own tests for keyboard use, text spacing, text size and forms. Each finding names its WCAG criterion.
Will passing make my site compliant?
No automatic tool can promise that. Passing means no barrier was found by the automatic tests; some criteria always need a person to check them.
Does it check every screen size?
The free tool checks the page at a laptop size. A free account checks 5 sizes, where phone-only barriers such as small tap targets and content that needs sideways scrolling also show up.
Do I need an account?
No. You can run a few free checks without one. Your result has a private link that we never list or index.
