Paste your text and switch it to UPPERCASE, lowercase, Title Case or Sentence case — instantly, right in your browser.
Is my text uploaded anywhere?
No. The conversion runs entirely in your browser with JavaScript — nothing is sent to a server, stored, or logged.
What does Title Case capitalize?
The first letter of every word, except short connectors (a, an, the, and, or, of, to, in, on, at, for, nor, but) unless they start the sentence — the style used for headlines and titles.
What is Sentence case?
The first letter of each sentence capitalized and the rest lowercased — standard prose. The converter detects sentence ends at . ! and ?, and keeps the pronoun "I" capitalized.
Does it work for long documents?
Yes — there is no length limit, because the text never leaves your device. Very long texts convert as fast as short ones.
