What file format is recommended for saving fonts for future use?

The recommended file format for saving fonts for future use is OpenType Font (OTF). This format is highly versatile and supports a variety of typographic features, including ligatures, alternate characters, and multiple language support, making it suitable for professional design work. OTF files can be easily installed on various operating systems, enabling consistent font usage across different platforms.

While EPS (Encapsulated PostScript), PDF (Portable Document Format), and AI (Adobe Illustrator) files may contain font information, they are not specifically designed for saving fonts for future use. EPS and AI are primarily used for vector graphics and illustrations, whereas PDF is intended for document distribution and may embed fonts rather than save them separately for reuse. Thus, OTF serves as the best option for font management and future application in design projects.
