How to Convert Text Case

The Case Styles, Explained

UPPERCASE turns every letter capital, useful for headings or emphasis. lowercase turns every letter small, handy for cleaning up text that was typed with the caps lock on. Title Case Capitalizes The First Letter Of Each Word, the style used for headlines and titles. Sentence case capitalizes only the first letter of each sentence, the way ordinary prose is written.

Good Uses for This Tool

Fixing text that was accidentally typed in all caps, formatting a heading or title consistently, cleaning up text copied from a source with inconsistent capitalization, or quickly matching a style guide's casing rules without retyping anything by hand.

Is It Actually Private?

Yes. The conversion happens entirely in your browser — nothing you type is ever sent to a server.
