Case Converter
Switch text between UPPERCASE, lowercase, Title Case, camelCase, and six more — live.
Paste any text, pick a format, and get the converted version instantly: Sentence case, lower case, UPPER CASE, Title Case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, or aLtErNaTiNg. The output updates live as you type, and nothing is ever sent to a server — the conversion runs entirely in your browser.
Writers use it to rescue paragraphs typed with Caps Lock on and to style headlines with proper Title Case, where minor words like “a”, “and”, and “of” stay lowercase unless they open or close the title. Developers use it to flip identifiers between camelCase, snake_case, kebab-case, and CONSTANT_CASE without touching a build tool.

Frequently asked questions
How does Title Case handle small words like “a” and “of”?
It follows the standard editorial rule: minor words — articles (a, an, the), short conjunctions (and, or, but), and short prepositions (of, in, on, to, at, by) — stay lowercase unless they are the first or last word of the title or follow terminal punctuation like a colon.
What is the difference between camelCase and PascalCase?
Both remove spaces and capitalize word boundaries. camelCase starts with a lowercase letter (myVariableName) and is common for JavaScript variables; PascalCase capitalizes the first letter too (MyClassName) and is the convention for class and component names.
Can I convert several lines at once?
Yes. Paste as many lines as you like — sentence and title case are applied per sentence and line, while programming cases like snake_case convert each line into its own identifier.
How do I fix text accidentally typed in ALL CAPS?
Paste it and click Sentence case. Everything is lowercased, then the first letter of each sentence is re-capitalized, and standalone “i” becomes “I” — much faster than retyping.
Is my text uploaded anywhere?
No. The converter is plain JavaScript running in your browser. Your text is never transmitted, stored, or logged — it works even if you go offline after the page loads.
