What actually changes
OTF and WOFF2 are not the same picture in two wrappers.
The CFF outlines are kept as they are and the font is repacked with Brotli compression in the WOFF2 container. No curves are converted, unlike an OTF to TTF conversion.
Worth knowing first
WOFF2 compresses CFF outlines less dramatically than TrueType ones, because its glyph transform is designed for the glyf table. The saving is real but smaller than the numbers usually quoted for TrueType-based fonts.
Questions
OTF to WOFF2, answered
Should I convert to TTF first?
No. That re-approximates every curve for no benefit. WOFF2 handles CFF outlines directly.
What about subsetting?
Subset before compressing. Removing unused glyphs saves far more than any compression choice.
