Convert text between UPPERCASE, lowercase, Title Case, Sentence case, and more — one click, with smart handling of small words.
About this tool
Fixing capitalization by hand is tedious — accidentally leaving Caps Lock on can otherwise mean retyping a whole paragraph. A case converter transforms the text in place.
Title Case here follows the common style-guide convention: every word is capitalized except short "minor" words (a, an, the, of, to, and so on) unless they start a sentence. Sentence case capitalizes only the first word of each sentence.
Convert, then hit Copy — the converted text goes straight to your clipboard.
Everything runs locally in your browser — your text is never uploaded, stored, or shared.
Frequently asked questions
What is the difference between Title Case and Capitalized Case?
Capitalized Case capitalizes every single word. Title Case follows publishing convention and keeps short words like "a", "of", and "the" lowercase unless they begin the title.
Does it preserve my line breaks and punctuation?
Yes. Only letter casing changes — spacing, line breaks, numbers, and punctuation are untouched.
Which case should I use for headlines?
House styles differ: AP and many US publications use Title Case for headlines, while most UK publications and many websites use Sentence case. Pick one and be consistent.
