How do I convert an OTF font to DFONT using LetsConvert?

Upload your OTF file, select DFONT as the output format, and click Convert. The converter repackages the font data into the classic Mac data-fork format, preserving glyph outlines and basic metrics. Once done, download the DFONT file and install it in your Mac's Font Book or classic system folder.

Why should I convert OTF to DFONT instead of using OTF directly?

DFONT is required by legacy Mac OS applications that expect classic font suitcase formats. It also ensures compatibility with older Mac OS 9 and early OS X versions, and may reduce file size due to a simpler table structure. Some older software simply will not recognize OTF, so converting is necessary.

Does the conversion preserve OpenType features like ligatures and advanced kerning?

OTF's advanced GSUB/GPOS tables may not map to the classic DFONT container. Our conversion preserves basic character outlines, widths, and kerning pairs, but advanced OpenType typographic features (e.g., swashes, stylistic sets) may be discarded because DFONT's spec lacks support for them. For standard text use, visual fidelity remains intact.
