Frequently asked questions
What is a .woff file?
A compressed font format designed specifically for fast loading and use on websites via CSS @font-face.
Can I edit a .woff file?
Partially. .woff files can be edited with the right tool (such as Any web browser), but not with just any text editor.
Does having a .woff 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.
