Convert OTF to TTF
Convert a .otf font to .ttf in your browser. Convertur parses the outlines and rewrites them as a TrueType glyf font — processed locally, nothing uploaded.
What is the difference between OTF and TTF?
Both are sfnt fonts, but OpenType fonts often store outlines as CFF (PostScript cubic curves), while TrueType fonts use glyf (quadratic curves). Some older software and pipelines only accept TrueType.
Why convert OTF to TTF?
A few tools, game engines, and embedded systems expect a TrueType glyf font and reject CFF-based OpenType. Converting to TTF makes the same typeface usable in those environments.
How the conversion works
Convertur parses the OpenType font with opentype.js, reads every glyph outline, and writes a new TrueType font with glyf and loca tables. Cubic curves are approximated as quadratics as part of that rewrite.
What to expect
The converted TTF keeps the same characters and metrics. Because CFF curves are re-expressed as TrueType outlines, extremely fine curve details may shift by a sub-pixel amount, which is imperceptible at normal sizes.
