Frequently asked questions
What is a .ttf file?
A widely-supported outline font format developed by Apple and Microsoft, used across desktop and web.
Can I edit a .ttf file?
Partially. .ttf files can be edited with the right tool (such as Font Book (macOS)), but not with just any text editor.
Does having a .ttf extension mean the file is safe?
No single extension can guarantee that. Fonts are rendered by the operating system or an app and carry generally low risk. Still, only install fonts from sources you trust. Always consider where the file came from, not just its name.
