Convert pt3 to cff

What is the difference between .pt3 and .cff?

Description: PostScript Type 3 consists of glyphs defined using the full PostScript language, rather than just a subset. Because of this, a Type 3 font can do some things that Type 1 fonts cannot do, such as specify shading, color, and fill patterns.; The Common File Format (CFF) is a standardized file structure designed to facilitate the sharing, exchange, and preservation of data across various platforms and applications. It is not tied to a specific domain but is rather a generic format that can be adopted by different types of software and systems for a wide range of data types. The CFF aims to provide a common framework that ensures data interoperability and accessibility, making it easier for users to work with data across different tools without the need for extensive conversions.
