💡 Why use Case Converter?

Consistent capitalization looks professional and is sometimes required — headlines in Title Case, code or tags in lowercase, or fixing a message someone typed in all caps. Converting instantly saves you from retyping and catching every letter by hand.

The four cases and when to use them

A note on Title Case rules

Traditional Title Case capitalizes the first and last words and all major words, but leaves short conjunctions, articles and prepositions (a, an, the, and, but, of, to) lowercase unless they start the title. Different style guides vary slightly, so pick one and be consistent.

Many modern brands and publications now prefer Sentence case for headings because it feels friendlier and is easier to read. When in doubt, match the style already used around your text.
