Common questions
What contrast ratio should my text meet?
WCAG level AA asks for at least 4.5 to 1 for normal text and 3 to 1 for large text. Level AAA asks for 7 to 1 and 4.5 to 1. The Contrast checker shows the ratio for your colors and which levels they pass.
Are my images uploaded to make a collage or favicon?
No. The Collage maker, Favicon generator and Color picker run in your browser. Your images are processed on your device and are not sent to our server when you build or download the result.
Which favicon sizes do I need?
Most sites need a small ICO or PNG for browser tabs and a larger PNG for home screen shortcuts. The Favicon generator creates the common sizes from one image, and you add the provided tags to your page head.
