Text Case Converter

Convert text between uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, and alternating case. Everything runs locally in your browser — your inputs are not uploaded to produce the result.

Each word starts with a capital letter. Styles vary for small words like “of” — this tool capitalises every word for simplicity. Common for filenames, URLs, and code identifiers. camelCase and PascalCase are typical in programming.

Letters change case; most punctuation stays. Identifier modes may replace spaces and symbols with separators. Tweak the inputs above to compare options, then copy or note the result you need.

Title case in publishing often leaves small words lowercase; this tool capitalises every word for predictability. Identifier modes (camelCase, snake_case) are for code and filenames, not prose.

Paste, pick a case, copy out. Punctuation usually stays put except where identifier modes replace spaces. For sorting or de-duplicating lists, use the dedicated line tools after you normalise case.
