What does the Case Converter do?
Paste any text and switch it to a different letter case in one click — UPPERCASE, lowercase, Title Case, Sentence case, or the developer formats camelCase, PascalCase, snake_case, and kebab-case. It’s ideal for tidying headings, fixing accidental caps lock, or turning a label into a variable or slug.

Frequently Asked Questions
What is the difference between camelCase and PascalCase?
Both join words with no spaces and capitalise each word after the first. camelCase keeps the first letter lowercase (myVariableName); PascalCase capitalises it too (MyVariableName). Developers use camelCase for variables and PascalCase for class names.
What are snake_case and kebab-case for?
snake_case joins words with underscores (user_id) — common in databases and Python. kebab-case joins them with hyphens (user-id) — common in URLs, slugs, and CSS class names.
Does it work with non-English letters?
Yes. Upper/lower/title/sentence case use Unicode-aware conversion, so accented and many non-Latin letters are handled correctly.
Is my text private?
Completely. The conversion runs entirely in your browser with JavaScript — nothing leaves your device.
