Frequently asked questions
What is Title Case?
Title Case capitalises the first letter of each word — commonly used in titles, headlines and proper names.
What is Sentence case?
Sentence case capitalises only the first letter of each sentence (after . ! ?), like normal prose.
Is there a character limit?
No. The conversion runs entirely in your browser, so you can paste large amounts of text without limits.
