OpenType (OTF) is the font format Microsoft and Adobe built on TrueType, adding advanced typographic features and optional PostScript (CFF) outlines.

About WOFF
WOFF (Web Open Font Format) is a W3C wrapper that compresses a TrueType or OpenType font for use on websites.
Web fonts loaded with CSS @font-face; all current browsers support it.
WOFF2 compresses better, so WOFF is now mainly a fallback for old browsers.
Why convert a font to WOFF? For older browser support: it compresses the font and carries embedding permissions, and legacy sites still expect it.
