Common uses

• Fixing accidental caps lock.
• Formatting titles and headings.
• Cleaning up pasted text for documents and posts.

Every case style, one click

UPPERCASE turns everything into capitals, lowercase removes them, Title Case Capitalises Main Words for headings, and Sentence case capitalises only the first letter of each sentence. The most common real-world job is rescuing text typed with caps lock on, which sentence case fixes instantly without retyping.

Title case done properly

Correct title case is trickier than capitalising every word: style guides keep short words like a, an, the, and, or, of and in lowercase unless they start the title. The converter follows that convention, so headings come out the way editors and style guides expect rather than Looking Like Every Word Was Capitalised.
