- Description
- 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.
- An OTF file is a font file saved in the OpenType format developed by Adobe and Microsoft. It combines aspects of the PostScript and TrueType font formats. OTF fonts are fully scalable, meaning the characters can be resized without losing quality.
