The Web Open Font Format (WOFF) is a font format specifically designed for use on the web. It allows web designers to use custom fonts on their websites without compromising loading speed. WOFF files are compressed, making them smaller and faster to download compared to traditional font formats. WOFF was developed to improve font licensing and usage on the internet. It supports various font types, including TrueType and OpenType, and is widely supported by modern web browsers. This format helps ensure that text appears consistently across different devices and platforms, enhancing the overall user experience.
