About this tool

Different contexts call for different capitalization: a heading wants Title Case, a variable name wants camelCase or snake_case, a constant wants CONSTANT_CASE. Retyping text by hand to match is tedious and error-prone. This tool converts your text into nine common case styles instantly.

Frequently asked questions

How does Title Case handle small words like "the" or "of"?
It lowercases common short words (articles, conjunctions, short prepositions) in the middle of a title, while always capitalizing the first and last word, matching typical title-casing conventions.
What counts as a "word" for camelCase or snake_case?
Runs of letters and numbers are treated as words, and everything else (spaces, punctuation, existing hyphens or underscores) is treated as a separator. So "hello-world 123" becomes "helloWorld123" in camelCase.
