Text Case Converter

Convert text between sentence case, title case, UPPER, lower, and more.

How to use this tool

  • Type or paste your text.
  • Choose the target case.
  • Copy the result.

How it works

Each case applies its capitalization rule over the tokenized text (words split on spaces/punctuation).

Tips

  • Use title case for headlines and sentence case for body copy.
  • For code, camelCase and snake_case keep multi-word names readable.

Limitations

Title-case small words (a, an, the, of) are lowercased by default; override if your style guide differs.
