In January 2023 Adobe apps stopped loading PostScript Type 1 fonts — thirty years of purchased typefaces, orphaned. Convert yours to OTF and keep working.
OTF — it keeps the PostScript-style outlines exactly and installs everywhere; this is the right answer for design work. TTF converts the curves (fine for office use). WOFF2 is for websites. The converter is FontForge, the long-standing open-source font editor.
The outlines are. Two honest caveats: kerning lived in the companion metrics file
(.afm/.pfm), which a single-file upload doesn’t carry, so tight
headline pairs may need a nudge; and hinting is regenerated, so tiny sizes on low-DPI screens
can render slightly differently. For print and design work, neither usually matters.
Converting for your own continued use of a licensed font is generally what foundries expect now that the format is dead — several published exactly this guidance around the 2023 cutoff. Redistribution is a different matter; check your license. And the conversion happening in a private temp folder that’s wiped immediately doesn’t hurt.
It’s written to a private temporary folder for the few seconds the conversion engine needs, then deleted — nothing is retained, logged or shared. No account, no email, no “files kept for 24 hours” fine print. These are often someone’s letters, family records or old business files; we treat them accordingly.
