A case converter tool transforms text between different letter cases. Common cases include: UPPERCASE (all capital letters), lowercase (all small letters), Title Case (first letter of each major word capitalized), Sentence case (only first word of each sentence capitalized), camelCase (first word lowercase, subsequent words capitalized - used in programming), PascalCase (every word capitalized - used for class names), snake_case (words_separated_by_underscores), and kebab-case (words-separated-by-hyphens). These tools are essential for consistent text formatting across documents, code, websites, and databases.
Title Case capitalizes the first letter of every major word (nouns, verbs, adjectives, adverbs, and pronouns), while minor words (articles, conjunctions, prepositions) are typically lowercase unless they're the first or last word. Example: "The Quick Brown Fox Jumps Over the Lazy Dog". Sentence case only capitalizes the first letter of the first word in each sentence and proper nouns. Example: "The quick brown fox jumps over the lazy dog. This is a normal sentence." Title case is used for titles, headings, and book/movie names, while sentence case is used for normal paragraph text.
