How to convert OTF to TTF
- Add your .OTF file - drop it in the box above or click to browse.
- Convert it to .TTF in a few seconds.
- Download your new .TTF file.
What to expect
- Conversion is not lossless: cubic Bezier curves (CFF/OTF) are approximated as quadratic curves (TrueType), which is invisible at normal display sizes but means the TTF is not byte-identical to the original.
- OpenType layout features - ligatures, kerning, small caps, alternates - are stored in tables independent of the outline format and are fully preserved through conversion.
- Check the font license before converting; many commercial fonts prohibit modification or redistribution, signalled by the
fsTypefield embedded in the font file.
Frequently asked questions
Will the converted TTF look different from the original OTF?
At normal display sizes the difference is invisible. Hinting may be slightly less refined at very small sizes on low-DPI screens, but for most uses the output is indistinguishable from the original.
Are ligatures and special characters lost during conversion?
No - OpenType layout features (GSUB/GPOS tables) are independent of the outline format and travel through the conversion intact.
Why is the converted TTF file larger than the source OTF?
Quadratic curves require more control points than cubic curves to describe the same shapes, so the
.ttf typically grows 10-30 % compared to the source .otf.Can I convert back from TTF to OTF?
Yes - tools like FontForge support the reverse direction, but the same approximation caveat applies; the resulting
.otf will have reconstructed cubic curves, not the exact original PostScript outlines.Programs that convert OTF: FontCreator · Fontographer · TypeTool · Fontographer for Mac · TypeTool for Mac · Glyphs · FontLab Studio · DTL OTMaster
