Case Converter
Ten text case styles — from Sentence case to camelCase — live as you type.
Title Case follows publishing convention — small words like “a”, “of” and “the” stay lowercase unless they start the title.
Convert text between ten case styles instantly: Sentence case, lowercase, UPPERCASE, publishing-correct Title Case, Capitalize Each Word, and the developer set — camelCase, PascalCase, snake_case and kebab-case (plus aLtErNaTiNg for the memes). Fix Caps-Lock accidents, format headlines properly, and generate variable names, live as you type.
How to use it
- Paste or type your text.
- Click a style — the result appears immediately and keeps updating as you edit.
- Copy the result, or feed it back as input to chain conversions.
Frequently asked questions
What is the difference between Title Case and Capitalize Each Word?
Title Case follows publishing rules — minor words (a, an, the, of, in…) stay lowercase mid-title. Capitalize Each Word uppercases every single word regardless.
What are camelCase, snake_case and kebab-case for?
Programming and web conventions: camelCase for JavaScript variables, snake_case for Python, kebab-case for URLs and CSS classes. The converter strips punctuation and joins words correctly.
Can it fix text typed with Caps Lock on?
Yes — paste it and hit Sentence case. Capitals after full stops are restored automatically.
Does converted text update if I edit the input?
Yes — once you pick a style, the output re-converts live as you type.
