FAQ

  • How do I use the favicon on a website?
    Upload the generated favicon.ico file to your site and reference it with a link tag such as rel="icon" in the page head.
  • Are files uploaded to a server?
    FormatKit is designed for browser-based conversion where supported. Some formats depend on browser capabilities, and the privacy page explains current limitations.
