Title Case Converter: what it does
Paste a headline, a blog post title, a YouTube title or a list of chapter names, and get it in proper title case. The rules follow the big style guides (Chicago and AP): capitalise the first and last word and every important word; keep articles (a, an, the), short conjunctions (and, but, or, nor, for, so, yet) and short prepositions (of, in, on, to, at, by, up…) lower case, unless they start the title, end it or come right after a colon. Each line is treated as its own title, so a whole list converts at once. Acronyms and brand names such as SEO, NASA and iPhone stay as you typed them.
How to use it
- Type or paste your text into the box.
- Pick a case: Sentence, Title, lower, UPPER, Capitalized, or a code case such as camelCase.
- The result updates as you type. Untick “Keep acronyms” if you want every word changed.
- Click “Copy”, or download the result as a .txt file.
Tips
- Words after a colon start with a capital: “Small Business Marketing: A Guide for Beginners”.
- Both parts of a hyphenated word are capitalised (“Long-Term Plan”), except short minor words (“Step-by-Step”).
- AP style capitalises prepositions of four letters or more (“With”, “From”, “Over”). If your publication uses AP, check those words after converting.
- For YouTube titles and blog posts, title case usually looks more polished; for news-style headlines and subheadings, many sites now use sentence case.
- Names and brands are never changed when “Keep acronyms” is on, so “iPhone Tips for SEO” keeps its odd capitals.
Frequently asked questions
Which words are not capitalised in title case?
Articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet) and short prepositions (as, at, by, in, of, off, on, per, to, up, via and others). They are capitalised when they are the first or last word, or come after a colon.
Is this AP style or Chicago style?
It follows the rules both share, which covers almost every title. The main difference: AP capitalises prepositions of four or more letters (With, From, Into), Chicago keeps all prepositions lower case. This converter keeps short prepositions lower case and capitalises long ones except “from”, “into”, “onto”, “over” and “with”.
Should “is” and “are” be capitalised?
Yes. They are verbs, and verbs are always capitalised in title case, however short: “What Is SEO”, “Why We Are Here”.
Can I convert many titles at once?
Yes. Put each title on its own line. Each line gets its own first-word and last-word capitals.
Is my text uploaded?
No. The conversion happens in your browser. Nothing is sent to our servers.
