Today I found a contact form plugin for my website and started watching a tutorial video to install it.
I’m learning about the different image formats that can be used to create a favicon. And for those who don’t know what a favicon is, it is that tiny logo/icon that displays in a browser tab when you are navigating on a website.
Image Formats
Below is what I’ve learned so far. These are some of the most common image formats used for favicons. These formats below are named after the three to four letter acronym you’ll see at the end of their filenames.
- ICO format (icon): This is the most common format for favicons and it is compatible with all common browsers.
- GIF format (Graphics Interchange Format): This format is rather gimmicky for a favicon and will be difficult for users to see clearly.
- JPG format (Joint Photographic Experts Group): This format is rarely used for favicons and not one of the highest quality formats.
- PNG format (Portable Network Graphics): This a common format but it has the drawback of not being visible to someone using Internet Explorer as their browser.
- APNG format (Animated Portable Network Graphics): This format is a PNG image that has been animated like a GIF and it shares the same drawbacks as the GIF.
- SVG format (Scalable Vector Graphics): This type of image can be resized while maintaining high image quality and not slowing down a website it’s used on.
Final Tips
The World Wide Web Consortium (W3C) has some recommendations. It suggests that favicons should always be named “favicon.ico” and put in the root directory of a website. A little redundancy can help favicons appear correctly on all browsers. Accomplish this by using both an .ico and a .png version for your website.
