What are system fonts vs web fonts

System fonts are the typefaces that are pre-installed on a user's operating system. They include fonts like Arial, Times New Roman, and Verdana, which are available on most computers and devices. Using system fonts can enhance the loading speed of a website since they do not require any additional downloads.

On the other hand, web fonts are fonts that are served over the web and can be used on websites via CSS. These fonts are not necessarily installed on the user's device and usually require a web font service such as Google Fonts or Adobe Fonts. Web fonts offer a wider variety of choices and the ability to maintain brand consistency across different platforms.
