Title case sounds like a simple rule: capitalise the words. In practice, it has two versions that look different, and which one you want depends on where the text is going.
Paste your title above and pick a style. The result updates as you type.
Headline style
This is the default and it is the version most editors mean by title case. The first and last words are capitalised, and so are the words that carry meaning, and a short list of small words is left in lowercase: a, an, the, and, but, or, nor, for, on, at, to, by, of, in, up, as. So “the quick brown fox jumps over the lazy dog” becomes “The Quick Brown Fox Jumps Over the Lazy Dog”.
Notice “over” is capitalised there. Different style guides disagree about prepositions. AP style capitalises words of four letters or more, so “over”, “from” and “with” take capitals. Chicago style lowercases every preposition however long. This tool follows the short-word rule, which suits most blogs, newspapers and book titles, and it is easy to tweak a word or two by hand if your house style differs.
Verbs stay capitalised even when they are short, which is why “is” and “be” are capitalised in “What Is a Text Repeater?” and a lot of tools get that wrong.
Capitalise every word
The second setting gives every word a capital, small words included: “The Quick Brown Fox Jumps Over The Lazy Dog”. It is not correct for sentences or article headlines, but it is common for product names, menu items, button labels and navigation links, where consistency matters more than grammar.
Where the tool needs a human
It works on words, not meaning. A few places to check afterwards:
The first word after a colon is not capitalised automatically, though most guides want it. Acronyms like NASA and USB are lowercased by the conversion and should be retyped. Brand names with their own styling, such as iPhone or eBay, come out as “Iphone” and “Ebay”. Hyphenated terms get a capital on each part, “Well-Known” for “well-known”, which is the usual convention for headings. And a title made of several lines gets only the final word of the whole text treated as last.
For web pages, sentence case is now the more common choice for headings and many style guides recommend it. Our short piece on title case versus sentence case lays out the trade-offs, and the sentence case converter does the other version. For other styles, the case converter shows them all.
