How to convert TTF to OTF
- Add your .TTF file - drop it in the box above or click to browse.
- Convert it to .OTF in a few seconds.
- Download your new .OTF file.
What to expect
- TrueType hinting (cvt, fpgm, prep tables) is dropped when converting to CFF outlines - text at small sizes on Windows may look slightly softer.
- Simply renaming
.ttfto.otfoften works because both share the sfnt container; only do a full conversion if CFF outlines are specifically required. - Check the font license before converting - many commercial fonts prohibit format conversion even for personal use.
Frequently asked questions
Does renaming .ttf to .otf work?
Often yes, because both formats use the sfnt container and modern apps read the internal format tag. Only run a full conversion if the receiving app specifically requires CFF (PostScript) outlines.
Is the conversion lossless?
Glyph shapes are preserved, but TrueType hinting is lost when converting to CFF - for print or large display sizes this difference is invisible.
Can I convert OTF back to TTF?
Yes - FontForge handles the reverse conversion with the same process and the same curve-refitting trade-offs.
Will the converted OTF work in all apps?
OTF works wherever TTF does on current systems (Windows 10+, macOS, Linux); only very old apps might behave differently.
