How the rules behave on this string
Every conversion starts from the same tidy-up: runs of spaces collapse to one and the ends are trimmed, while line breaks are preserved. Uppercase and lowercase then apply directly. Sentence case lowercases everything and re-capitalises the first letter after a full stop, question mark, exclamation mark or line break. Title case lowercases everything and re-capitalises the letter that follows the start of a line, a space, a quote, a bracket or an apostrophe.
Title Case here is a blanket rule: every word gets a capital, including the short ones. Writers who follow AP or Chicago style would leave of, the and and lowercase in a headline, so the Title Case line above is a starting point rather than a finished house style.
Counted rather than eyeballed, the string runs 28 characters across 6 words, of which 23 are letters and 5 are punctuation, digits or spaces.

Frequently asked questions
What does each of the four results mean?
They are four separate passes over the same 28-character string. UPPERCASE and lowercase are the obvious ones. Title Case capitalises the first letter of every word, and Sentence case capitalises only the first letter of each sentence while forcing everything else down. The converter on the homepage builds them with the identical rules.
Which one should I paste into my document?
For a headline or a section title, Title Case is the conventional choice in English web copy, with the caveat that style guides keep short articles and prepositions lowercase. Sentence case reads more naturally in product interfaces and is what most design systems now ask for.
