How to Use Case Converter

Type or paste your text into the input box.
Choose a case style — UPPERCASE, lowercase, Title Case, or Sentence case.
The converted text updates instantly in the output box.
Use Copy to grab the result. Nothing is uploaded — conversion happens in your browser.

UPPERCASE and lowercase change every letter; Title Case capitalizes the first letter of each word; Sentence case capitalizes only the first letter of each sentence. Numbers and punctuation are left unchanged.
