- 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.
- Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
