Convert OTF to WOFF
The OpenType container with CFF (PostScript-flavour) outlines. Read wherever a font can be added, and written back out on-device by unwrapping a WOFF - the outlines pass through untouched either way.
A web font is an OpenType font (TTF or OTF) wrapped in a compressed container so it downloads smaller. Lolly converts between them losslessly on-device: unwrap a WOFF to a plain TTF or OTF, or wrap one up, rebuilding the table directory and checksums each way. TrueType and CFF outlines both pass through untouched. WOFF2 (Brotli) is read-detected but not yet written.
