How it works
Handy for article titles, names typed with the wrong case, text pasted with Caps Lock stuck on, or standardizing formatting before posting to social media or documents. "Title Case" capitalizes the first letter of every word (good for headlines); "Sentence case" treats the text as sentences and only capitalizes the start of each one; "Toggle" flips the case of every individual letter (useful for text effects). Numbers, punctuation, and spacing are never touched — only letters change case.
