WOFFWOFF2

WOFFWOFF2 is not an officially standardized font format. The term is not recognized as a distinct specification in web typography and may reflect a misnomer, a branding choice, or a shorthand for WOFF or WOFF2 used in a particular context. For clarity, this article describes the two established formats and how they relate to any nonstandard naming you might encounter.

WOFF, or Web Open Font Format, is a wrapper for font data designed for use on the web. It encapsulates TrueType or OpenType font outlines in a compressed container with metadata and licensing information, making it easier to deliver fonts securely over the internet. WOFF has widespread browser support and is commonly distributed by font providers as a webfont file.

WOFF2 is the successor to WOFF and offers superior compression by using the Brotli algorithm. This results in smaller file sizes and faster font loading, which can improve page performance on slower networks. WOFF2 is widely supported by modern browsers and is often the preferred choice for new webfont deployments. Converting fonts from TTF/OTF to WOFF2 is a common step in webfont workflows, with dedicated tools available for batch conversion.

If you encounter the term WOFFWOFF2 in documentation or code, it is best to verify the intended meaning with the source. It is likely a mislabeling or shorthand for WOFF or WOFF2 rather than a separate, recognized format. In practice, webfont deployment should specify either WOFF for broader compatibility or WOFF2 for improved compression, with appropriate fallbacks.
