Fonts define the graphical representation of an individual character in the text, such as its size, display style, weight, color, etc. TTF (True Type Font) works fine on all digital platforms and gives excellent quality on-screen and in printed documents. On the other hand, the WOFF (Web Open Font Format) is mostly used in web pages. It contains format-specific compression and additional XML metadata. In certain cases, we may need to convert true-type fonts into Web fonts.
