Privacy, accuracy and common mistakes

Inputs are designed to be processed in the browser wherever the workflow allows. For sensitive material, review the page, your browser environment and your own data-handling rules before using any online tool.

For professional work, treat Contrast Checker as a practical helper rather than the final authority. Check the source data, selected options and expected format before using the output in a live project.

Common mistakes to avoid: Do not rely on appearance alone for accessibility. A palette can look harmonious while still failing contrast for small text.
