What is a TTF file?
TTF – TrueType font. TTF (TrueType) is the font format of Windows and macOS since the 1990s: the letter shapes as curves, with spacing and hints for small sizes. Every operating system, office program and design tool installs it, and browsers load it too.

OTF – OpenType font. OTF (OpenType) is the modern font format by Adobe and Microsoft: it holds PostScript or TrueType outlines and can add ligatures, small capitals and other typographic features. Every operating system installs it.

Good to know
- The font is converted by FontForge: the letter shapes, spacing and kerning are kept. Hinting (the instructions that sharpen small text) is made again or left out, which modern screens do not show.
- The TrueType outlines are kept as they are inside an OpenType font file.
- Check the font's licence before converting and using it: ConvertKitty does not look at what the licence allows.
Frequently asked questions
Is converting TTF to OTF free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my TTF files uploaded anywhere?
This conversion runs on our server, because converting fonts needs FontForge, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the TTF file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the OTF look the same as the TTF?
Yes: the letter shapes, spacing and kerning are kept. Hinting, the instructions that sharpen small text on old screens, is made again or left out, and you will not see the difference on modern screens.
Can I convert several TTF files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
How long does converting TTF to OTF take?
In our tests even a font with 60,000 glyphs took between 1 and 9 seconds to convert; ordinary fonts finish in a moment.
