Case Converter
Fix the case in one click
Left caps lock on, or pasted a heading that came through in block capitals? This converter rewrites your text five ways: all uppercase, all lowercase, Title Case where every word is capitalised, Sentence case where only the first letter of each sentence is, and the alternating case used for a sarcastic tone online. The result replaces the text in the box so you can copy it straight out.
Sentence case is the one people reach for most, since it rescues a whole paragraph typed in the wrong case without retyping a word. For headline-correct capitalisation that lowercases small joining words, use the title case converter.
