Capitalize your headlinethe way the style guide says.
Stop eyeballing which words get a capital. Paste your headline and get it back in every case that matters, title case, AP style, sentence case, UPPER and lower, each one a single tap to copy. Consistent capitalization is the cheapest polish on a page, and the first thing a careful reader notices when it's wrong.

Clean capitalization is the easy part. I write the line worth capitalizing.
Title case: "The Art of the Follow-up Email"
A perfectly cased headline still has to earn the click. I write the headlines, subject lines, and page copy that do, then make sure every one of them is consistent down to the last lowercase 'the.' Bring me a page that looks fine but isn't converting and I'll show you, free, what to rewrite first.
Plain English
Capitalization is a tell. Get it right.
Title case is the convention of capitalizing the important words in a heading while leaving the small connecting words lowercase. The catch is that 'important' is defined by a style guide, not by gut feel, and the rules differ just enough between guides to make people guess. The result is the same headline capitalized three different ways across one website.
The two systems most marketers meet are title case and AP style. Both capitalize the major words, nouns, verbs, adjectives, adverbs, pronouns, and always the first and last word. Both lowercase the minor words: articles (a, an, the), short conjunctions (and, but, or), and the short prepositions (of, to, in, on, for). Sentence case is the looser, more modern alternative: capitalize only the first word and any proper nouns, exactly like a normal sentence.
This converter applies all of those rules at once so you can see the same line every way and pick the one your brand uses, then copy it in a single tap. No more capitalizing 'Of' by accident or shouting in all caps because you weren't sure. Decide your house style once, run every headline through it, and your pages read as if one careful person wrote them all.
The formula
Title case = capitalize every major word; lowercase the minor words (a, an, the, and, but, or, of, to, in, on, for…) unless first or last
'the art of the follow-up email' → Title case: 'The Art of the Follow-Up Email'. Note 'of' and the second 'the' stay lowercase because they're minor words, but the leading 'The' is capitalized because it's the first word. Sentence case gives 'The art of the follow-up email' instead.
How to capitalize headlines without second-guessing
01Pick one house style
Title case or sentence case, decide once and write it down. The specific choice matters far less than applying the same one across every page, ad, and email.
02Always cap the first and last word
Even a minor word like 'to' or 'the' gets a capital when it opens or closes the headline. This is the rule people most often miss.
03Lowercase the small connectors
Articles, short conjunctions, and short prepositions (of, to, in, on, for) stay lowercase in the middle of a title. That restraint is what makes title case look professional rather than shouty.
04Use sentence case for subject lines
Email and push subject lines in sentence case read as personal, not promotional, and often lift open rates. 'Your invoice is ready' beats 'Your Invoice Is Ready'.
05Never set a full headline in all caps
ALL CAPS kills readability and reads as yelling. Save it for short labels and badges; let case carry the emphasis in the headline itself.
06Capitalize proper nouns in every mode
Even in sentence and lower case, brand names and place names keep their capitals. A converter can't know your proper nouns, so give the output a quick human pass.
07Watch hyphenated words
In title case, capitalize both parts of a meaningful compound: 'Follow-Up,' not 'Follow-up.' Decide your rule and keep it consistent.
08Run every headline through the same filter
Paste it here before it ships. Thirty seconds of consistency is the difference between a page that looks edited and one that looks rushed.
The vocabulary
- Title case
- Capitalize the major words and the first and last word; lowercase the minor words (articles, short conjunctions, short prepositions).
- AP style
- The Associated Press headline convention: like title case, but it explicitly lowercases all prepositions of three letters or fewer.
- Sentence case
- Capitalize only the first word of the line (and any proper nouns), exactly as you would write a normal sentence.
- Minor words
- The small connecting words that stay lowercase mid-title: a, an, the, and, but, or, of, to, in, on, for, and similar.
- Proper noun
- A specific name (a person, brand, or place) that keeps its capital letters in every case, including lowercase mode.
Title case questions, straight answers
Title case capitalizes the important words in a heading, nouns, verbs, adjectives, adverbs, and pronouns, plus the first and last word, while leaving minor words like 'a,' 'the,' 'of,' and 'to' lowercase. It's the standard for headlines, article titles, and book titles. Paste your line above and this tool applies the rules for you.
