How Font Collection (TTC / OTC) to WOFF conversion works
Font Collection (TTC / OTC) parse and rights check → fidelity diagnostics → WOFF write and verify
Reading Font Collection (TTC / OTC)
TTC and OTC input exposes every contained face for explicit selection and writes selected faces as individual results.
Creating WOFF
WOFF output preserves compatible sfnt tables and license metadata in a webfont container.
Font rights and output integrity
Only convert fonts you have the right to use. Restricted, bitmap-only, missing, malformed, or conflicting embedding rights block output, and required license metadata must survive result verification.
