Website Contrast Checker

Paste a page URL to check text and background colour contrast against WCAG guidelines. Free, no signup.

Only check pages and files you are allowed to use.

Paste a URL or upload a screenshot only if you own the site or have permission. Do not upload pictures of other people or documents that contain personal data you should not share.

We use what you submit only to produce this result. We do not keep the URL, the text, the screenshot or the report after the check. We do not build profiles.

I have the right to check this page or file.

An honest note

This checks detectable colour pairs on the page. It does not prove full accessibility compliance.

Want to test two specific colours instead? Use the Colour Contrast Checker.
