Title Case Converter

Omni Calculator’s title case converter is a practical tool that helps you format headings and titles correctly, without guessing which words should be capitalized.

If you’ve ever wondered what a title case is or struggled with sentence case vs. title case, our tool lets you see the differences instantly. You can use it as a reliable title capitalization tool that follows widely accepted capitalization rules, including AP title case and APA title case.

Instead of memorizing complex rules for title case, you simply paste your text and get a clean, style-appropriate result ready for articles, academic papers, or web content.

Title case, also known as headline case, is a capitalization style primarily used for titles and headings in English. In simple terms, title case meaning refers to capitalizing the first and last words of a title and all major words, while leaving minor words (such as articles, short prepositions, and some conjunctions) in lowercase unless they appear at the beginning or end. This is why you might see a headline written as “The Quick Brown Fox Jumps over the Lazy Dog.”

You’ll most often encounter title case in book titles, headlines, chapter names, and blog posts, where proper capitalization improves readability and visual clarity. For example, even this article uses “Title Case Converter” rather than “Title case converter” — not because the lowercase version is wrong, but because title case makes the heading clearer and easier to read.

Examples of title case:

• The Quick Brown Fox Jumps over the Lazy Dog;
• How Small Changes Can Improve Everyday Productivity; or
• Why Data Science Matters in Modern Decision Making.

While the core idea of title case remains consistent, the rules for title case vary by style guide, making a title case converter especially useful. Read more in our dedicated “What is title case?” article.

The difference between sentence case vs. title case lies in how words are capitalized and where each style is used. In sentence case, only the first word of the sentence and proper nouns are capitalized, just like in regular writing. These rules make sentence case a natural choice for complete sentences, paragraphs, and UI text where readability and a conversational tone matter.

In title case, most major words are capitalized, while minor words remain lowercase unless they appear at the beginning or end. This style is commonly used for headlines, titles, and headings because it draws attention and clearly separates the title from the surrounding text.

For example, a classic proverb like “All that glitters is not gold” is written in sentence case, with only the first word capitalized, while “All That Glitters Is Not Gold” uses title case when presented as a heading.

If you only need to change letter casing without applying title capitalization rules, try our lowercase to uppercase converter or an uppercase to lowercase converter instead.

There is no single, universal set of rules for title case. Instead, capitalization depends on the style guide you follow, which is why different publications format titles differently. Most guides agree on the basics:

1. Capitalize the first word of a title;
2. Capitalize all major words (such as nouns, verbs, adjectives, adverbs, and pronouns); and
3. Keep minor words (articles, short prepositions, and some conjunctions) lowercase.

The differences appear in the details, and you can see below how different style guides handle title capitalization:

1. AP, APA, and AMA title case generally lowercase short prepositions and coordinating conjunctions (such as in, on, at, by, for, and, but, or), capitalizing them only when they are four letters or longer (e.g., with, from, between), with small variations between guides.
2. MLA title case is stricter, lowercasing all prepositions regardless of length as well as coordinating conjunctions like and, but, or.
3. Chicago style lowercases most conjunctions (and, but, for, or, nor) and prepositions(in, on, with, over), but always capitalizes the first and last words of a title, even if they would normally be lowercase.
4. Bluebook title case, commonly used in legal writing, follows rules similar to APA and AMA, lowercasing coordinating conjunctions (and, or, but) and short prepositions (in, on, for, by).
5. NYT title case has its own editorial conventions, selectively lowercasing certain short prepositions (at, by, in, for) while capitalizing others of the same length (up, off, out).

A running example

Let’s look at the base sentence:

Learning to work with data in the modern world

• AP / APA / AMA title case:

  Learning to Work With Data in the Modern World

  (short prepositions like “to” and “in” are lowercased)

• Chicago title case:

  Learning to Work with Data in the Modern World

  (“with” and “in” are lowercased; first and last words remain capitalized)

• MLA title case:

  Learning to Work with Data in the Modern World

  (all prepositions are lowercased, regardless of length)

• NYT title case:

  Learning to Work With Data in the Modern World

  (selective capitalization of short prepositions)
