About the Title Case Converter

This tool converts text into Title Case, Sentence case, UPPERCASE, or lowercase using the standard major/minor word rule that publishers, style guides, and headline writers rely on. Type or paste a title, pick a style, and get the converted text along with word and character counts.

The Title Case rule

Title Case capitalizes every "major" word — nouns, pronouns, verbs, adjectives, and adverbs — and lowercases "minor" words: articles (a, an, the), coordinating conjunctions (and, but, or, nor), and short prepositions (at, by, for, in, of, on, per, to, via, and similar). Two rules override the minor-word list: the first and last word of the text are always capitalized, and the first word after a colon or dash is always capitalized, even if it appears on the minor-word list.

Worked example

Applying the rule to "the ultimate guide to title case: rules and examples" gives "The Ultimate Guide to Title Case: Rules and Examples." Note that to and and stay lowercase in the middle of the title, while the and examples are capitalized because they are the first and last words, and Rules is capitalized because it follows the colon.

Hyphenated words and acronyms

Each segment of a hyphenated compound is capitalized independently — mother-in-law becomes Mother-In-Law. Words that are already written in all capitals, such as NASA or USA, are treated as acronyms: with "Keep as-is" selected they are left untouched, since capitalizing only the first letter would turn them into Nasa or Usa.

Other conversion styles

  • Sentence case capitalizes only the first letter of the text (and, in a full implementation, the first letter after ., !, or ?), leaving the rest lowercase.
  • UPPERCASE converts every letter to a capital, often used for emphasis or acronym-style headings.
  • lowercase converts every letter to a lowercase, useful for slugs, filenames, or stylistic lowercase titles.

Frequently Asked Questions

What is Title Case?
Title Case is a capitalization style where the first letter of most words is uppercase, following the convention used for book titles, headlines, and article headings. Major words (nouns, verbs, adjectives, adverbs, pronouns) are capitalized, while minor words such as articles, short prepositions, and coordinating conjunctions stay lowercase unless they open or close the title.
Which words stay lowercase in Title Case?
Common minor words that stay lowercase are articles (a, an, the), coordinating conjunctions (and, but, or, nor), and short prepositions (at, by, for, in, of, on, per, to, via). This tool always capitalizes the first and last word of the text and the first word after a colon or dash, even if it is on the minor-word list.
How are hyphenated words and acronyms handled?
Each part of a hyphenated compound is capitalized on its own, so mother-in-law becomes Mother-In-Law. Words that are already fully uppercase, such as NASA or USA, are treated as acronyms and left unchanged when the acronym-preserving option is selected, since forcing normal capitalization would break them into Nasa or Usa.
How is Title Case different from Sentence case?
Sentence case capitalizes only the first letter of the text (and, in a full implementation, the first letter after sentence-ending punctuation), leaving every other word lowercase unless it is a proper noun. Title Case capitalizes most words throughout, following the major/minor word rule, which is why it looks different even on the same input text.
