What is a .woff file?

The Web Open Font Format (WOFF) is a font format for use in web pages. It was developed to provide lossless compression of fonts, reducing file size and improving page load times. WOFF files contain font data, metadata, and private-use data. The metadata includes information about the font's license, designer, and other relevant details. The compression algorithm used in WOFF is based on zlib, which is widely supported and efficient. WOFF fonts are typically used with the @font-face CSS rule, allowing web developers to embed custom fonts directly into their websites. This eliminates the need for users to have the fonts installed on their local machines, ensuring consistent rendering across different platforms and browsers. WOFF has become a widely adopted standard for web fonts, supported by all major browsers. Its successor, WOFF2, offers even better compression and is also widely supported. Using WOFF helps improve website performance and provides greater design flexibility by allowing the use of a wider range of fonts.
