The Web Open Font Format 2.0 (WOFF2) file is a modern font format designed specifically for use on the web. It is an evolution of the WOFF format, offering improved compression and thus smaller file sizes, which enhances web performance by reducing the time it takes for fonts to load. WOFF2 supports the same customization and features as its predecessor, but with more efficient encoding and compression mechanisms.
SFD (Spline Font Database) is the native, text-based source format of the FontForge font editor. It stores a font's glyph outlines, metrics, kerning, OpenType tables and editing state, so a font can be reopened and edited losslessly and then exported to TrueType, OpenType, WOFF or Type 1.
