WOFF (Web Open Font Format) is a font format specifically designed and optimized for use on the web.
What is WOFF Font File?
Developed in 2009 by Mozilla in cooperation with Type Supply, LettError, and others, WOFF was created to provide lightweight, fast-loading web fonts that could be embedded via CSS using the @font-face rule. It is essentially an OpenType or TrueType font container wrapped with compression and additional metadata, making it a standard W3C recommendation for typography on the internet.

You can use ConvertX tools like woff-to-ttf, woff-to-woff2, or woff-to-otf to seamlessly convert your font files.
Most desktop applications require TrueType (TTF) or OpenType (OTF) formats. You need to convert WOFF to TTF before installing it on your system.
