What is Title Case?+
Each word starts with a capital letter. This converter uses simple capitalization of every word, which is the common convention for headings and buttons.
What are camelCase, snake_case and kebab-case for?+
They are naming styles used in programming and URLs: camelCase joins words with capitals, snake_case with underscores and kebab-case with hyphens.
Does it handle accents and other alphabets?+
Yes. Conversion uses Unicode-aware casing, so accented and non-Latin characters are handled correctly where casing applies.
