The seven writing cases in the converter — what each does, and when to use it.
Hello. My dog is a cat!
Everything lowercase, except the first letter of each sentence — after a full stop, question mark, exclamation mark or a new line.
Use for: Body text, UI labels, buttons, captions and most headlines in modern design systems.
hello. my dog is a cat!
Every letter becomes lowercase.
Use for: Tags, file names, a quiet typographic look, or as a clean starting point.
HELLO. MY DOG IS A CAT!
Every letter becomes uppercase. A German ß becomes SS.
Use for: Short labels, eyebrows above headings, drawing titles and signage. Use sparingly — long passages are hard to read.
Hello. My Dog Is A Cat!
The first letter of every word is uppercase, the rest lowercase.
Use for: Names, list items and places where every word should stand out equally.
The Art of the City and the Sea
Like Capitalized Case, but small words (a, an, the, and, or, of, in, on, to, for) stay lowercase unless they start the line.
Use for: Book, article, project and presentation titles.
hElLo. My DoG iS a CaT!
Letters switch between lower and upper. Spaces, numbers and punctuation are skipped, so the rhythm continues across words.
Use for: Mocking or playful tone in social posts and memes.
hELLO. mY DOG IS A CAT!
Every uppercase letter becomes lowercase and vice versa.
Use for: Fixing text typed with Caps Lock accidentally on.
Only letter casing changes. Accented letters like å, ä, ö, æ, ø, é, ñ and ü convert correctly, while emojis, numbers, punctuation, line breaks, tabs, extra spaces, URLs and Markdown are left exactly as you typed them.
