Case converter FAQ
What is the difference between Title Case and Capitalized Case?
Title Case follows a style guide and keeps small words like a, the and of in lower case. Capitalized Case makes every single word start with a capital letter, no exceptions.
What is the difference between AP, APA and Chicago title case?
AP style lowercases short words such as a, an, the and short prepositions. APA lowercases most words of three letters or fewer. Chicago lowercases articles, coordinating conjunctions and prepositions regardless of length.
What is inverse case used for?
Inverse case flips every letter's capitalization, which some people use for stylized usernames or to make a short phrase stand out.
Does this work on long documents?
Yes, there is no length limit. Very long text updates a little slower since the whole document is reprocessed on every keystroke.
