Aa Title Case Converter, Capitalize Headlines the Right Way

What is the Title Case Converter?

Title case is a capitalization style used for titles and headings where the important words start with a capital letter and the minor words stay lowercase. It is different from simply capitalizing every word: in true title case you write "The Quick Brown Fox Jumps Over the Lazy Dog", not "The Quick Brown Fox Jumps Over The Lazy Dog". The second "the" stays lowercase because it is a minor word sitting in the middle of the title. Getting this right is what separates a polished headline from one that looks like a beginner typed it.

The rule this converter follows is straightforward. Split the text into words, then always capitalize the first word and the last word no matter what they are. For every word in between, capitalize it unless it belongs to a short list of minor words, in which case it stays lowercase. The minor words are the common articles, short conjunctions, and short prepositions: a, an, and, as, at, but, by, for, if, in, nor, of, on, or, per, so, the, to, up, via, vs, and yet. This matches the spirit of the major editorial style guides while staying simple and predictable.

Because the first and last word are always capitalized, a title like "up in the air" becomes "Up in the Air": the leading "up" is capitalized as the first word, "in" and "the" stay lowercase as minor words in the middle, and "air" is capitalized as the last word. This edge rule is the single most common thing people get wrong when they capitalize titles by hand, and it is exactly what an automatic headline capitalization tool is for.

Alongside title case, the converter produces four other everyday cases so you rarely need a second tool. Sentence case lowercases everything and then capitalizes the first letter of each sentence, which is ideal for body copy and modern UI headings. UPPERCASE and lowercase are literal transforms of every letter. Capitalize Each Word capitalizes the first letter of every single word with no minor-word exceptions, which is what you want for proper-noun lists, name fields, or a strict start-case look.

A toggle labelled "Smart minor words" controls the difference between real title case and simple word capitalization. When it is on you get editorial title case with the minor-word list applied. When you turn it off, the Title Case box behaves like Capitalize Each Word so you can force every word to start with a capital, which is handy for brand names or stylised headings that intentionally capitalize small words.

Everything updates live as you type, so you can paste a draft, watch all five versions appear at once, and copy whichever one you need. There is no character limit imposed by a server because the tool does all the work locally in your browser using plain JavaScript.

When to use it

• Formatting book, song, movie, and course titles that follow title case conventions.
• Cleaning up email subject lines and marketing headlines where the wrong capitalization looks unprofessional.

Minor words kept lowercase in Title Case (unless first or last)

Common mistakes to avoid

• Capitalizing every word and calling it title case. Writing "The Quick Brown Fox Over The Lazy Dog" with a capital on the middle "The" is start case, not title case. True title case keeps minor words like "the", "of", and "to" lowercase when they sit in the middle of the title.
• Leaving the first or last word lowercase. Minor words are only lowercase in the middle. The first and last word are always capitalized, so "up in the air" is "Up in the Air", not "up in the Air". This tool applies that edge rule automatically.
• Using title case for full sentences. Title case is for titles and headings, not running text. For body copy use Sentence case, which capitalizes only the first letter of each sentence and leaves the rest lowercase.
• Expecting proper nouns to be detected. The converter capitalizes by position and word list, not by meaning. In Sentence case a name like "new york" will not be auto-capitalized because the tool cannot know it is a place. Fix proper nouns by hand or use Capitalize Each Word.
• Assuming every style guide uses the same minor words. Different style guides draw the minor-word line slightly differently, especially for prepositions of four letters or more. This tool uses a widely accepted short list; if your publication has its own rule, adjust the output afterward.
