Frequently asked questions
WOFF or WOFF2?
WOFF2 compresses much better and is the current standard: use it unless you must support very old browsers (IE9-IE11), where WOFF fits.
Any quality or glyph loss?
No: WOFF is a lossless compressed container of the same font.
Does it take OTF?
Yes, WOFF accepts OpenType CFF as well as TrueType.
How do I declare it in CSS?
src: url('font.woff') format('woff') inside your @font-face, ideally after the woff2 source.
