Case Converter
Convert text to UPPERCASE, lowercase, Title Case, Sentence case or Capitalized Case in one click -- your line breaks and spacing stay exactly as they were. Your text never leaves your browser.
How it works
Paste or type your text, then choose a case. The result updates instantly and you can copy it with one click. UPPERCASE and lowercase change every letter; Capitalized Case capitalizes each word; Title Case keeps short words like "and", "of" and "the" lowercase in the middle of a line; Sentence case capitalizes the start of each sentence. Letters from most languages are supported, and your spacing and line breaks are never changed. Everything runs locally in your browser.
Is my text sent to any server?
No. The case converter runs entirely in your browser. The text you type or paste is never uploaded, stored, or included in analytics. We do not require sign-up or login.
What is the difference between Title Case and Capitalized Case?
Capitalized Case capitalizes the first letter of every word. Title Case follows common headline style: it capitalizes every word except short words such as a, an, the, and, of, in and to -- unless they are the first or last word of a line or follow a colon.
What does Sentence case do?
Sentence case makes everything lowercase and then capitalizes the first letter of each sentence (after a full stop, question mark, exclamation mark or new line), and the word "I". Proper nouns such as names are not detected automatically, so you may need to fix a few by hand.
Does it change my spacing or line breaks?
No. Only letters change case. Spaces, tabs, blank lines and punctuation are kept exactly as they were.
