Convert CFF to SFD

CFF, or Compact Font Format, is a file extension used in computer technology for efficient storage of font data. CFF was developed as part of Adobe's PostScript technology to streamline font file sizes while maintaining high-quality vector graphics. Its primary use is in embedded systems, print, and digital media, providing a compact and versatile format for typefaces. The history of CFF dates back to the early 1990s when it was introduced to address the need for more efficient font management in professional publishing and graphic design environments.

The SFD (Spline Font Database) file extension is primarily used by FontForge, a font editing software. SFD files are ASCII-based, making them human-readable and easily transferable across the internet. They store comprehensive font data, including outlines, character data, and bitmap fonts. Introduced by FontForge, SFD files have evolved to support multiple layers and complex font features. This format facilitates detailed font design and editing, ensuring compatibility across various operating systems.
