Screen readers
Blind or low-vision people listen to the page. They need alt text, labels, headings and link names.

Page accessibility
People who use a screen reader, the keyboard or a magnified screen keep running into the same obstacles. We read your page and point them out, one by one.
Who is it for?
About one person in five lives with a disability, and many more have a temporary one: a broken arm, tired eyes, a phone in bright sunlight. An accessible site is simply a site that works for more people.
Keyboard only
People who can't use a mouse move with the Tab key. Every button must be reachable, in a sensible order, and visibly highlighted.
Zoom and contrast
Many people enlarge the text or struggle with pale grey on white. The page must stay readable at 200% and keep enough contrast.
Test it yourself in five minutes
- Put the mouse away. Press Tab repeatedly: can you see where you are at all times, and reach the menu, the forms and every button?
- Zoom to 200%. Ctrl and + (Cmd and + on a Mac): does the text stay readable without scrolling sideways?
- Listen to it. NVDA is free on Windows; VoiceOver is built into Mac and iPhone. Listen to your home page for two minutes.
- Fill in your contact form with the screen reader on: does each field say what it expects?
Frequently asked questions
Does a good grade mean my site is accessible?
No. An automatic check catches roughly a third of the problems. A good grade means the basics visible in the code are in place; the human test above covers the rest.
Why is contrast only partly checked?
Real colours come from style sheets, images and scripts, and only a browser knows them all. We measure the colours written directly in the page; for the rest, test your pairs with the Colour contrast tool.
Should a decorative image have alt text?
It should have an empty one: alt="". That tells screen readers to skip it. What causes trouble is a missing alt attribute altogether.

Is my page accessible?
Enter the page address: the tool reads its HTML and points out, one by one, the obstacles faced by people who use a screen reader, the keyboard or a magnified screen. You get a grade from A to F.
