Frequently asked questions
Is the Color Converter free?
Yes. Color Converter is completely free with no sign-up, no usage limits and no watermarks.
Is my data private?
Yes. The Color Converter processes everything in your browser. Signed out, nothing is saved; signed in, your inputs sync privately to your own account.
What contrast ratio does WCAG require?
WCAG 2 AA requires at least 4.5:1 for normal text and 3:1 for large text; AAA requires 7:1 and 4.5:1.
What is OKLCH?
A perceptually uniform color space: equal steps in lightness or chroma look like equal changes to the eye, which makes it great for building palettes and themes in CSS.
Does it work on my phone?
Yes. Toolbench runs in any modern browser on desktop, tablet or phone — there is nothing to install.
