Frequently Asked Questions
How does the Image Contrast Checker work?
Upload any PNG, JPG or WebP image — a design mockup, screenshot, or UI preview. Click on the text area to sample the foreground color, then click on the background area to sample the background color. We instantly calculate the WCAG contrast ratio and show you AA/AAA pass/fail results. You can also paste CSS to extract colors from a code snippet.
What types of images work best?
Screenshots of websites, design mockups, UI component previews, and app screens work great. The tool samples the exact pixel you click, so solid color areas give the most accurate results. Avoid heavily compressed JPGs with artifacts around text edges — use PNG for crisp results.
Do I still need the regular Contrast Checker?
They complement each other. The Image Contrast Checker is for visual sampling — when you have a design file or screenshot and want to pick colors by eye. The regular Color Contrast Checker is for precision work — when you already have hex codes and want to test them directly. Use whichever fits your workflow.
