Paste any English text and pick a case. All conversions run locally in your browser — nothing is uploaded.
Title Case follows AP/Chicago style: short words like a, an, the, of, in, to stay lowercase unless they’re the first or last word. Sentence case also fixes standalone i → I. The programming-style conversions (camelCase, snake_case, etc.) correctly split existing camelCase or PascalCase input on the way through.
