Frequently Asked Questions
Title Case capitalizes the first letter of each major word while keeping articles, conjunctions, and short prepositions lowercase (following standard title capitalization rules). Capitalize Words capitalizes the first letter of every word regardless of its grammatical function, which is useful for headings, labels, or when you simply want to “capitalize my title” completely.
