Common Questions

The converter follows the most widely accepted English style guide rules used by AP Style and Chicago Manual of Style: capitalize major words, skip minor words (articles, short prepositions, coordinating conjunctions) unless first or last.

Minor words include: articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet), and short prepositions (at, by, for, in, of, on, to, up).

Capitalized case capitalizes every word. Title case applies grammatical rules, keeping minor words in lowercase unless they open or close the title.
