Case Converter

Convert text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case and more in one click.

Paste your text and choose a case. Title Case follows common US headline style: it keeps short words such as a, and, of and the lowercase unless they are the first or last word.

Developer cases

  • camelCase and PascalCase for variables and class names
  • snake_case and CONSTANT_CASE for Python and environment variables
  • kebab-case for URLs and CSS classes

Private by design

This tool runs entirely in your browser. The text you enter is never uploaded, stored or logged, so it is safe to use with private documents, and it keeps working offline once the page has loaded.

Tips

  • Paste with Ctrl + V (Cmd + V on Mac). Formatting is removed automatically, so you work with plain text.
  • Results update as you type. There is no submit button.
  • Install Typeri from the header to keep this and every other tool one tap away, even offline.
