Button Contrast Checker

Test all buttons and links on your webpage with just one click. Check if you have are compliant with WCAG 2.1 contrast guidelines.

Button Contrast Checker launched on September 19, 2019 with 8 votes, #1,008 of 3,296 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 7 years on.

What it does

Enter your domain and we test if your buttons have enough contrast and are compliant with WCAG 2.1. We were in need of a tool to test the contrast of all buttons and links of a page at once. So we built Button Contrast Checker. You can use it for free. Buttons have several states: default , hover , focus , active , disabled , etc. Many websites have insufficient contrast in these states. Maybe it's because the tools don't help much in this regard, but not anymore. In a few seconds you'll know if your buttons and links have enough contrast in the three most common states. Let's picture this scenario: we launch a website with perfect buttons and great contrast. Later down the road, unaware of…from aditus.io
