How Title Case works here
Title Case capitalizes the first and last word and every major word, but keeps short articles, conjunctions and prepositions (a, an, the, and, but, or, for, of, on, in, to, at, by…) in lower case — the convention used by AP and Chicago style.
“Capitalize Each Word” is the simpler version: every word starts with a capital letter, with no exceptions.
Frequently asked questions
What is the difference between Title Case and Capitalize Each Word?
Title Case keeps small words like “a”, “the”, “of” and “in” lower case unless they start or end the title. Capitalize Each Word capitalizes every word.
How do I convert text to sentence case?

Can I undo a conversion?
