UPPER, lower, Title, camelCase, snake_case, kebab-case. Free, no signup. Runs entirely in your browser; files are never uploaded.

## How it works

Type the source in the input box and see a live preview of all nine cases in a grid below. Click any case to push that version into a copyable output box. UPPER and lower are straightforward. Title Case capitalizes every word. Sentence case capitalizes only after sentence-ending punctuation. camelCase strips non-alphanumeric separators and capitalizes word boundaries after the first. PascalCase is camelCase with the first letter capitalized. snake_case uses underscores between words. kebab-case uses hyphens. CONSTANT_CASE is upper-snake. Useful for renaming variables, normalizing file names, formatting URL slugs, and titling articles. Handles UTF-8 well for Latin scripts; non-Latin scripts (CJK) pass through unchanged.

## How to use it

1. **Type your text.** All nine cases render live in a grid below the input.
2. **Pick a case.** Click the one you need — camelCase for variables, kebab-case for slugs, Title Case for headlines.
3. **Copy the result.** The chosen version lands in a copyable output box.

## Frequently asked questions

### What's the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (helloWorld). PascalCase capitalizes the first letter too (HelloWorld). Both omit separators.

### What does it do with non-Latin characters?

Latin-script characters (with accents) convert correctly. Non-Latin scripts (Cyrillic, Greek, CJK) pass through unchanged because case isn't defined the same way.

### Does it preserve numbers?

Yes. Digits stay where they are. "hello 2 world" becomes "hello-2-world" in kebab-case, etc.

### Is my text uploaded?

No. Case conversion runs locally.
