Case Converter
Convert text to upper, lower, title, sentence and camelCase.
About this tool
Transform text into every common casing style: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case and more. Perfect for writers and developers.
How it works
Each style is a small transform: Unicode-aware upper/lower, a word-boundary splitter for camel/snake/kebab, and a Title Case engine with a stop-word list that respects leading/trailing positions.
How to use Case Converter
- 1Type or paste your text.
- 2Click any case button — the output replaces the text and appears in the preview.
- 3Use the "copy" button next to each converted style.
- 4Reset to clear both boxes.
Examples
"hello world" becomes "Hello World" in Title Case and "helloWorld" in camelCase.
"user_profile_id" becomes "UserProfileId" in PascalCase.
"HELLO WORLD" becomes "hello-world" in kebab-case.
Pro tips
- Title Case keeps short connecting words like "and" and "the" lowercase where appropriate.
- camelCase and snake_case are handy when naming variables in code.
- Sentence case only capitalises the first letter — best for product copy and lists.
Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every major word; Sentence case capitalises only the first letter of the sentence.
Is Title Case applied intelligently?
Yes — small words (a, an, the, and, of, in, for, etc.) stay lowercase unless they start the phrase, matching most style guides.
Can developers use this for variable names?
Yes. camelCase, PascalCase, snake_case and kebab-case output are designed to drop straight into code.
