The W3C validation icons. Proudly show your commitment to Web standards.

How to use the Validation Icons
The W3C "valid" icons may be used on documents that successfully passed validation for a specific technology, using the W3C validation services. The image should be used as a link to re-validate the document. Read the Markup Validator's documentation on icons usage for more information on policies around these icons.

List of all W3C Validation Icons
The W3C Validation icons are all available in PNG, GIF, SVG and EPS. To link to a specific version directly, add .png, .gif, -v.svg or -v.eps to the generic URI (or browse the icons repository to see all versions).
