What advanced features does this case converter include?

Beyond standard uppercase, lowercase, and Title Case, it includes developer casings (camelCase, snake_case, kebab-case, PascalCase, dot.case), line sorting (A-Z/Z-A), line deduplication, find & replace with regex, prefix/suffix insertion, and URL slug generation.

How does the Title Case algorithm handle small words?

It intelligently respects English capitalization guidelines, leaving articles, conjunctions, and prepositions (a, an, the, and, but, or, for, in, on, of) lowercase unless they appear at the start of a line.

Is my text data stored or sent to any server?
