Title Case Converter

Convert a headline to title case in AP, Chicago, APA or MLA style, or to sentence case, and copy the result. Paste one headline per line to convert several at once.

Acronyms and names typed with capitals inside them (AI, CRM, iPhone, McKinsey) are kept as you typed them. A line typed all in capitals is converted like any other.

The conversion happens in your browser; what you type is not sent to ParrotNotes and is not put in the page address. Only the style you pick is in the link.

How each style capitalizes a title

All four capitalize the first word, the first word after a colon and every noun, verb, adjective, adverb and pronoun, however short (Is, Be, It). They differ on the small words in between:

What a converter cannot decide for you

The rules turn on what a word is doing, and a converter only sees the word. "Up" is a preposition in "Up the Hill" but part of the verb in "Follow Up With Buyers", where every style capitalizes it; the converter treats short words like up, on, in, out and over as prepositions, so check phrasal verbs (Log In, Set Up, Sign Out) in the middle of a title. AP capitalizes "to" when it is part of an infinitive; the converter keeps "to" lowercase.

In sentence case it cannot tell a name from an ordinary word, so a name you typed as "Texas" comes out as "texas" unless it starts the line. Names typed with a capital inside them (iPhone, LinkedIn) and acronyms (CRM, AI) are kept as typed. These are our reading of each guide's published rules, not the guides' own tool, and house style can override any of them.

Headlines, subject lines and the story behind them

Newsrooms, blogs and sales teams all have the same problem: five people, five ways of capitalizing. Agree on one style for headlines and one for email subject lines, write it down, and run every headline through the same rule before it goes out.

The headline is the last thing you write. The quote that makes it is usually something the source said twenty minutes into the interview, which is easy to paraphrase wrong from memory. Record the interview, work from the transcript, and quote it word for word.

The interview behind the headline

Record the interview with ParrotNotes on your phone, get the transcript and a summary, and pull the exact quote for the headline instead of the one you half remember.
