Frequently asked questions
What is the difference between Title Case and Capitalize Each Word?
On this tool, Title Case first lowercases the whole text and then capitalises each word, giving a clean, uniform title. Capitalize Each Word only raises the first letter of every word and leaves the remaining letters exactly as you typed them.
When should I use Sentence case?
Sentence case is the normal style for everyday writing: only the first word of each sentence and proper nouns start with a capital letter. It is ideal for fixing paragraphs that were typed in ALL CAPS.
Does converting case change my original text?
No. Your input stays untouched in the top box; the converted version appears separately in the result box, so you can try every case style safely.
