How WOFF to WOFF2 conversion works
WOFF parse and rights check → fidelity diagnostics → WOFF2 write and verify
Reading WOFF
WOFF input is reconstructed to its sfnt tables and verified before any target is written.
Creating WOFF2
WOFF2 output uses the verified browser codec and is validated by decoding and reparsing the result.
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.
