How it works
Type or paste your text, then click a case button: the text case changer converts it in place, instantly. UPPERCASE and lowercase convert every letter; Title Case follows headline style and keeps minor words like "and", "of" and "the" lowercase; Sentence case capitalizes only the first word of each sentence. Everything runs as plain JavaScript in your browser — from uppercase to lowercase and back, your text is never uploaded anywhere, so it's safe for confidential content. Use Undo to step back to the text as it was before the last conversion.
Frequently asked questions
How do I change uppercase text to lowercase?
Paste your text into the box, click the "lowercase" button, and every letter is converted instantly. Use the Copy button to grab the result.
What is the difference between title case and sentence case?
Title case capitalizes the main words of a headline while keeping minor words like "and", "of" and "the" lowercase. Sentence case only capitalizes the first word of each sentence, the way a normal sentence is written.
Is it safe to paste confidential text into this case converter?
Yes. The conversion runs entirely in your browser with JavaScript — your text is never uploaded, stored or sent to any server.
