Convert JFPROJ to OTF

Verified by Adam B.· reviewed by FE Editorial ·updated Jul 26, 2026
QUICK ANSWER
Is it possible to convert JFPROJ to OTF?
Yes - JFPROJ converts to OTF.

Microsoft Font Maker, which creates .jfproj files, only exports to .ttf, not OTF. So the reliable path is to export your font as .ttf, then open it in FontForge and generate an .otf. Since Font Maker outputs simple TrueType outlines, the resulting OTF wraps the same glyphs rather than gaining true PostScript-style curves.

Why convert JFPROJ to OTF?

Designers want .otf because OpenType is broadly supported and can carry advanced typographic features. A .jfproj itself is just an editable project, so you first turn it into an installable font, then rewrap it as OTF.

How to convert JFPROJ to OTF

Microsoft Font Maker FREE

Open the .jfproj, then use Export to save a .ttf. This is the required first step because Font Maker cannot output OTF directly.

FontForge OPEN-SOURCE

Open the exported .ttf in FontForge, then choose File > Generate Fonts and pick OpenType (.otf) to produce the OTF.

Quality & what to watch

  • Font Maker can't make OTF itself, so the TTF export step is unavoidable.
  • Converting TTF to OTF keeps TrueType (quadratic) outlines wrapped in an OpenType container; it doesn't magically add PostScript curves or OpenType features.
  • Font Maker fonts are handwriting-based, so hinting and spacing are basic and the OTF inherits those limits.

Frequently asked questions

Why can't Font Maker export OTF directly?
Microsoft Font Maker only supports TrueType .ttf export. To get OTF you convert the exported TTF in a font editor like FontForge.
Is the OTF better quality than the TTF?
Not really. It's the same outlines in a different wrapper, so quality is essentially unchanged from the TTF you started with.
Can I use an online converter for the TTF to OTF step?
Yes. After exporting the TTF, tools like CloudConvert or Fontsource can produce the OTF if you'd rather not install FontForge.
