⚡Font Optimization

Reduce custom font file size by 90%+ with the official Font Simplification Tool.

Since Catime only displays numbers and symbols (0-9, :, .), most font characters are unnecessary.

Recommendation: Keep your original font files as backups. Future software updates may require additional characters beyond the current set.
