Case Converter

Paste your text, pick a case, and copy the result. Great for headings, titles, code and tidying up messy text.

The case styles explained

  • UPPERCASE / lowercase — every letter capital or small.
  • Title Case — the first letter of each word capitalised, ideal for headings.
  • Sentence case — only the first letter of each sentence capitalised.
  • camelCase / snake_case / kebab-case — common naming styles for programming variables, files and URLs.
Does it keep my punctuation?

UPPER, lower, Title and Sentence case preserve punctuation. The programming cases (camel, snake, kebab) strip punctuation to produce a valid identifier.
