Frequently asked questions
Is title case the same as capitalized case?
No. Capitalized Case capitalizes words after whitespace. Title Case keeps selected short words lowercase unless they are the first or last word on a line. Review the result against your preferred editorial style.
Can sentence case fix names and acronyms?
Sentence case lowercases the input and capitalizes detected sentence beginnings. It does not recognize proper names or preserve acronyms automatically. Review those terms yourself.
Can I undo a conversion by selecting another case?
Changing case again cannot reliably recover the original capitalization. Keep the original draft before converting.
