TTF to OTF Converter
Convert TrueType Font (TTF) files to OpenType Font (OTF) format instantly
What this conversion does
- Rewrites the glyph outlines from quadratic curves into the cubic curves used by PostScript/CFF fonts. This step is mathematically exact, so shapes are unchanged.
- Produces a true
OTTO-flavoured OpenType file, not a renamed TTF. - Preserves the font's existing kerning and layout tables (
GPOS,GSUB). - Often required by print workflows and page-layout software that expect PostScript outlines.
Worth knowing: converting to OTF does not add typographic features. If the source TTF has no ligatures or alternates, the OTF will not have them either — those have to be drawn into a font by its designer. TrueType hinting is dropped, since it does not apply to CFF outlines.
Format Details
Why choose OTF?
The OpenType/CFF format is the standard for professional print and type design work, and its PostScript outlines are what many page-layout and prepress tools expect. The format also supports features such as contextual alternates and stylistic sets — where the font's designer has included them.
