Frequently asked questions
Is my text uploaded anywhere?
No. All conversions happen entirely in your browser. Nothing is sent to a server.
How does word splitting work for camelCase and snake_case?
The converter splits on whitespace, punctuation, underscores, hyphens, and camelCase boundaries (detected via regex). This means "myVar_name" and "MyVarName" both produce the same word tokens before rejoining in the target format.
What is the difference between Title Case and Capitalize Each Word?
Title Case follows editorial conventions: minor words (a, an, and, the, of, etc.) stay lowercase unless they are the first or last word. Capitalize Each Word uppercases the first letter of every word without exception.
