Title Case Converter

Title case is a set of rules for capitalizing words in headings and titles. Most words are capitalized, but certain short words like articles (a, an, the), prepositions (in, on, at, to, by, for, of), and conjunctions (and, but, or, nor) are kept lowercase unless they are the first word.

For example, "a walk in the park" becomes "A Walk in the Park" in title case. Notice that "in" and "the" remain lowercase because they are short words in the middle of the title, but the first "A" is capitalized because it starts the title.

Title case capitalizes the first word of a title along with all major words. Short prepositions (in, on, at), conjunctions (and, but, or), and articles (a, an, the) are typically left in lowercase unless they are the first word. Different style guides (AP, APA, Chicago, and MLA) have slightly different rules about which words to capitalize, but the core principle remains the same: emphasize the important words to create a clear, professional heading that immediately communicates the topic of the content that follows.

In most style guides, short prepositions (in, on, at, to, by, for, of, up), coordinating conjunctions (and, but, or, nor, so, yet), and articles (a, an, the) are kept lowercase unless they are the first word of the title. Hyphenated words vary by style guide: some capitalize only the first element, while others capitalize both parts. When in doubt, capitalize the first and last words and any word with four or more letters.

The converter recognizes approximately 3,000 proper nouns and abbreviations. After applying standard title case rules, it corrects words like NASA, iPhone, JavaScript, PostgreSQL, and place names like New York and Los Angeles to their canonical casing. This prevents acronyms from being incorrectly formatted as "Nasa" or "Html" in title case output.

The dictionary may not cover every proper noun, especially uncommon personal names or niche terms. If a word is not in the built-in list, it will follow the default title case rules.

Title case capitalizes most words in a heading, giving it a more formal and traditional appearance. Sentence case capitalizes only the first word and proper nouns, creating a more conversational and modern tone. Title case is the standard in most published books, newspapers, and academic papers. Sentence case is popular for blog posts, UI elements, and brands that favor an approachable voice. Choose the style that matches your audience and maintain it consistently across your content.
