Over time favicons have been standardized in terms of their format, size and location on a website. This standardization has developed from a need for favicons to be implemented consistently across different browsers and devices.This process of standardization began in 2005 when the World Wide Web Consortium (W3C) published a recommendation for favicons, which said that the file should be named favicon.ico and placed in the root directory of the website. Their recommendation also outlinked size and format requirements for the icon. The W3C then updated their own recommendations again in 2011, when they added additional image formats and sizes for favicons. They also included support guidelines for multiple icons across various devices.Favicon standardization has had several benefits. The primary one being that it means they are displayed properly across a variety of browsers and devices. Before standardization, they may have shown clearly on one browser, but not on another, affecting the user experience. It's also simplified the favicon creation process for web designers and developers, as they no longer have to design or format them specifically for different browsers and devices. One design and format should work. This also improves and standardizes the web experience for all web users.
