OTF Converter
OpenType with PostScript outlines. OTF files hold cubic PostScript outlines in a CFF table, inside the same sfnt container TrueType uses.
OTF is an OpenType font whose glyph outlines are cubic Bézier curves stored in a CFF or CFF2 table, and whose file opens with the tag OTTO. It uses the same sfnt container as TrueType. The extension records which outline format is inside, not a different kind of font.

What an OTF file is
An .otf file is an sfnt font, the same container a .ttf uses, carrying its glyph outlines in a CFF or CFF2 table as cubic Bézier curves rather than in glyf as quadratic ones. Files built this way open with the four-byte tag OTTO. Everything else, the cmap, the name strings, the OS/2 metrics, the GSUB and GPOS layout tables, is identical in kind to what a TrueType font carries.
The cubic outlines come from Adobe Type 1 and the Compact Font Format that succeeded it, which is why type designers and print workflows tend to prefer OTF: the curves match the way the drawing tools work and need fewer points to describe the same shape.
