— What it does

The Case Converter is a free tool that instantly rewrites your text in every common letter case: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Each variant has its own copy button so you can grab exactly the format you need. All conversions happen live in your browser.

  • Nine case variants generated at once, each with a one-click copy button.
  • Programmer-friendly cases: camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE.
  • Updates live as you type — no convert button to press.
  • Runs entirely in your browser — your text is never uploaded to a server.

Frequently asked

Is my text sent anywhere?
No. The Case Converter runs entirely in your browser with JavaScript. Your text is never uploaded or stored, so it is safe for private or sensitive content.
What is the difference between camelCase and PascalCase?
Both join words without spaces. camelCase keeps the first word lowercase (myVariableName), while PascalCase capitalizes every word including the first (MyVariableName).
When should I use snake_case, kebab-case or CONSTANT_CASE?
snake_case (lowercase with underscores) is common in Python and databases, kebab-case (lowercase with hyphens) suits URLs and CSS classes, and CONSTANT_CASE (uppercase with underscores) is used for constants and environment variables.
How does Title Case decide what to capitalize?
Title Case capitalizes the first letter of every word. Sentence case capitalizes only the first letter of each sentence and lowercases the rest.
