OTF to TTF Converter: what to know
OTF and TTF are both OpenType fonts; the difference is how the letter shapes are drawn. Most OTF files use CFF (Compact Font Format) outlines made of cubic Bezier curves, from the PostScript tradition, while TTF files use TrueType outlines made of quadratic curves. Some older software, embedded systems, games and tools accept only TrueType outlines, which is when an OTF to TTF conversion is needed.
This converter reads each glyph's outline and redraws every cubic curve as quadratic segments, splitting curves until the difference is under half a font unit, which is invisible at any practical size. Contours are written in TrueType's clockwise direction into new glyf and loca tables. Advance widths, kerning, the character map and OpenType layout features (ligatures, alternates) are carried over unchanged, with fresh checksums. It all runs in your browser, with no upload.
Two things are worth knowing. CFF hints can't become TrueType instructions, so the TTF has no hinting, which matters mostly for small text on older Windows setups. Variable fonts with CFF2 outlines and font collections (.otc) aren't supported yet.
Popular uses
- Using an OpenType font in software that only accepts TrueType
- Embedding a font in a game engine or device that needs TTF
- Preparing fonts for tools that convert or rasterize TrueType outlines
Tips for the best result
- If your app accepts OTF, keep using the original: it keeps the original curves and hints.
- For websites, convert the OTF to WOFF2 instead; no outline conversion is needed.
- Check the glyph count shown after conversion matches the original font.
- Make sure the font's license allows modifying or converting it before you distribute the TTF.
