What is a TTF file?

A TTF file is a font that can be installed in macOS, Windows, and other platforms. It is saved in the TrueType font format, which was created by Apple. TrueType fonts can be resized to any size without losing quality and look the same when printed as they do on the screen.

Apple developed and released the TrueType font format in the 1980s. Since its release, the TrueType format has become one of the most common formats used in both macOS and Windows.

Most modern fonts that you find on your PC or online are saved in the TTF format. However, you may also encounter fonts saved in the .OTF (OpenType) format.

How do I use a TTF file as a font?

To use a TTF file as a font, you must first install it on your system:

  • In Windows, you install fonts by placing them in the C:/​Windows/​Fonts directory.
  • In macOS, you install fonts by opening them in Apple Font Book and selecting the Install Font button.
  • In iOS and Android, you can use third-party apps, such as iFont, to install fonts. (Note that while they share the same name, the iOS and Android versions of iFont are developed by different developers.)

How to open a TTF file

You can open a TTF file in Microsoft Windows Font Viewer (Windows), Apple Font Book (Mac), or iFont (iOS, Android). Before opening a TTF file in Windows Font Viewer, you must place the file in the C:/​Windows/​Fonts directory. Otherwise, Windows will not recognize the file as a valid font file.
