About OTF to TTF

OTF to TTF is for fonts that come as .otf with PostScript (CFF) outlines when the software you're using asks for TrueType. Some older Windows programs, embroidery and cutting machines, game engines, display libraries for microcontrollers and app build tools only accept .ttf files.

Upload the OTF, confirm that you own the font or its licence allows converting it, and download the TTF. The curves are converted from the cubic outlines used by CFF to the quadratic outlines TrueType uses, which reproduces the letter shapes closely, while hinting for very small screen sizes may differ from the original.

FAQ

OTF to TTF: questions and answers

What's the difference between OTF and TTF?
Both belong to the OpenType family. OTF files usually contain PostScript (CFF) outlines, TTF files contain TrueType outlines, and some programs and devices only read TrueType. Collections in .ttc format are another case, and TTC to TTF splits them into single TTF files.
Will OTF to TTF change how the font looks?
The outlines are converted with high precision, so text looks the same to the eye at normal sizes. Hinting at very small pixel sizes can behave differently.
When do I need OTF to TTF?
When an app, a device or a build tool asks for .ttf and won't take .otf. For a website, the Web Font Generator takes the OTF directly and gives you WOFF2, WOFF and TTF plus the CSS.
Is there a free limit for OTF to TTF conversions?
Yes, 2 tasks in total for visitors and 2 a day for free accounts, with files up to 50 MB. VIP lifts the task limit.
Is my font file safe with this OTF to TTF converter?
It travels over HTTPS, is converted in an isolated process and is deleted with the TTF after one hour. Nobody looks at it.
