TransType 4
TransType 4 is a font format converter for macOS and Windows that converts fonts between multiple formats including Adobe PostScript Type 1, TrueType, and OpenType. It allows users to batch convert legacy fonts into modern OpenType formats (OTF and TTF) and web fonts (WOFF and EOT), and includes features for organizing, renaming, merging and splitting font families, applying effects, and generating font previews. It is used by typographers, designers and studios to modernize font collections, particularly as older PostScript Type 1 fonts have been deprecated in Adobe Creative Suite applications.

1 suggestionFontLab's official product page explicitly states that TransType 4 works on Apple Silicon, and the vendor lists it as compatible with "Intel 64-bit with Retina support, works on Apple Silicon" for macOS 10.6 through macOS 26 Tahoe. This indicates a Universal Binary or native build has already been shipped. Update to the latest version by downloading directly from fontlab.com/font-converter/transtype/ — FontLab's official installer will provide the native Apple Silicon build. If you installed TransType 4 previously from an older download, re-downloading the current version from FontLab will ensure you have the native build that will continue to run after Rosetta 2 is removed in macOS 28 (September 2028).
