What is a Favicon?
Favicon stands for 'Favorite Icon'. It refers to the small logo icon displayed alongside the website name on the browser's top tab or bookmark list. It is an essential element of website building that represents the site's identity and instills trust in visitors.
Why Do You Need a Dedicated .ico Format?
Although modern browsers recognize PNG or JPG files as favicons, older systems still using remnants of Internet Explorer or specific search engine bots (like Naver Search Advisor) only recognize the traditional .ico format as an official favicon when crawling site standards. Blog services like Tistory also often force the upload of `.ico` files in their settings.
Tips for Perfect Results
- Use Transparent PNGs: To prevent a white square border from appearing around your logo, upload a PNG file with a transparent background whenever possible.
- Square Images: Favicons use a 1:1 ratio. If your original image is rectangular, it may have empty margins or become distorted. It is best to prepare a square logo.
