What is a WOFF file?

WOFF (Web Open Font Format) is a font format designed specifically for use on websites. Developed by Mozilla in collaboration with Type Supply and other foundries, it wraps existing font formats like TTF or OTF with compression and metadata.

WOFF allows fonts to be embedded directly into websites via CSS, ensuring consistent appearance across platforms. It is supported by all modern browsers and is a key part of responsive web design.

How to open WOFF files

WOFF files are used in websites and linked through CSS using @font-face. They are supported by all modern browsers and require no installation on the user’s system.

You can convert WOFF files to TTF or OTF using FontForge or online converters like AnyConv for desktop use.
