Case Converter
Choose a target case and paste text; the converted result appears immediately. Programming cases (camelCase, snake_case, kebab-case) split words at spaces, punctuation and existing capital letters, line by line.
This tool runs in an isolated frame on tools.freetoolspro.com. Your files and inputs stay on your device, and advertising on this page cannot read them.
Title Case rules
Every word is capitalised except short articles, conjunctions and prepositions (a, an, and, of, the, to, …) after the first word. Style guides differ, so check names and acronyms.

Common questions
Will it keep acronyms like NASA?
Title and Sentence case lowercase the rest of each word, so acronyms need fixing afterwards. UPPERCASE and CONSTANT_CASE keep them.
Does it work for other languages?
Yes, it uses your browser’s locale-aware case mapping for letters such as é, ß and Ç.
