Title Case Converter

A title case converter helps you capitalize a heading according to a defined title style instead of simply making every word start with a capital letter. Paste your text into CapitalizeText.live, choose the style you need, and the title updates immediately. You can compare APA, AP, Chicago, MLA, Bluebook, AMA, New York Times, and Wikipedia style without typing the title again.

Title case is used for many kinds of headings and titles, including books, articles, presentations, research papers, songs, films, reports, legal materials, and web pages. The challenge is that English title capitalization is not controlled by one universal rule. Different style guides make different decisions about words such as prepositions, conjunctions, infinitives, and parts of hyphenated compounds.

That is the reason a useful title case converter needs style awareness.

What Is Title Case?

Title case is a capitalization system in which the first word and major words in a title are capitalized. Depending on the style, the last word may also be capitalized regardless of its grammatical role. Minor words can remain lowercase in the middle of the title.

Consider this text:

a practical guide to writing for the modern web

A title case result may look like:

A Practical Guide to Writing for the Modern Web

The exact output can change when you switch style guides. For example, a longer preposition may be capitalized in one system but lowercased in another. That difference is not a mistake. It reflects the selected editorial convention.

Title Case Is Not the Same as Proper Case

Many simple case converters label a feature “Title Case” when they are actually applying initial capitals to every word.

Input:

the art of writing for the web

Capitalize every word:

The Art Of Writing For The Web

Editorial title case:

The Art of Writing for the Web

The second result recognizes that “of,” “for,” and “the” can be minor words. A real title capitalization tool needs rules for word function, word length, location, punctuation, compounds, and exceptions.

How to Convert Text to Title Case

1. Paste or type the title into the editor.
2. Select Title Case.
3. Choose APA, AP, Chicago, MLA, Bluebook, AMA, NYT, or Wikipedia.
4. Review the live result.
5. Copy the converted title.

You can keep the same text in the editor while switching styles. This makes comparison much easier than checking separate rule lists manually.

APA Title Case

APA 7 uses title case for important contexts such as paper titles, headings, and titles of works when those titles appear in the text of a paper. APA defines major words to include nouns, verbs, adjectives, adverbs, pronouns, and words of four letters or more.

That four letter rule is important. A word such as “With” can be capitalized in APA title case even though it functions as a preposition.

Short articles, short prepositions, and short conjunctions can remain lowercase when they occur in the middle of a title and no position based rule overrides that treatment.

AP Title Case

AP style is widely associated with journalism, media, public relations, and marketing. For composition titles, AP title capitalization also capitalizes principal words and words of four letters or more.

AP writing should not be reduced to a generic headline formula. A newsroom or publication may apply a house style to headlines, and AP guidance for composition titles is not necessarily the same thing as the visual style a publication uses for every headline.

Use the AP option when AP title rules are specifically required.

Chicago Title Case

Chicago is a major publishing style. The 18th edition, released in 2024, changed a rule that matters to title capitalization. Prepositions of five letters or more are now capitalized in titles. This means older Chicago converters can produce outdated results if they still lowercase every preposition regardless of length.

Chicago also contains detailed guidance for hyphenated terms, subtitles, titles within titles, and names. If accuracy matters for publication, review any unusual construction rather than relying on a single simple word list.

MLA Title Case

MLA is widely used in humanities writing. English language titles are generally styled with the first word, last word, and principal words capitalized. Articles, coordinating conjunctions, and prepositions are generally lowercased in the middle of the title unless another rule applies.

MLA treatment of prepositions differs from styles that use a four letter or five letter threshold. This is one of the easiest places to see why style selection matters.

Bluebook Title Case

The Bluebook is used in United States legal citation. The 22nd edition was released in 2025. Rule 8 addresses capitalization, but legal citation contains additional rules for source titles, case names, abbreviations, and formatting.

A title case converter can help with ordinary capitalization, but it cannot decide every legal citation question from capitalization alone. Court rules, journal style, professor instructions, and local conventions may also control the final form.

AMA Title Case

AMA is used in medical and scientific publishing. The 11th edition remains current in 2026 and includes detailed capitalization guidance. Medical writing can contain organisms, drug names, scientific abbreviations, eponyms, and technical terms whose established capitalization should be preserved.

Use AMA style as a formatting aid, then review specialist terminology before submitting a manuscript.

What Words Are Capitalized in Title Case?

Although details vary, major title styles commonly capitalize:

• The first word
• Major nouns
• Pronouns
• Verbs
• Adjectives
• Adverbs
• Proper nouns
• The first word of a subtitle
• Other words defined as major by the selected style

Many styles also capitalize the last word even when it would normally be a minor word in the middle.

What Words Stay Lowercase?

Possible lowercase words include articles such as “a,” “an,” and “the,” coordinating conjunctions such as “and,” “but,” and “or,” and some prepositions.

The word “some” matters. APA, AP, Chicago, MLA, and Bluebook do not all define minor words identically. A converter should apply the selected style rather than one universal list.

Title Case With Colons and Subtitles

A colon often introduces a subtitle.

Example:

writing for the web: a practical guide

In title case, the first word after the colon is commonly capitalized:

Writing for the Web: A Practical Guide

This is true even when that word would normally be minor in the middle of a title. Similar position based rules can apply after other punctuation depending on the style.

Title Case With Hyphenated Words

Hyphenated compounds are a common source of mistakes because style guides do not handle every compound the same way.

Examples include:

self-report

state-of-the-art

anti-intellectual

cost-benefit

A converter can apply the general style rule, but the grammatical relationship between the parts may matter. Chicago 18 also changed some title treatment for compounds beginning with prefixes. When a hyphenated term is central to a publication title, verify the result against the current style manual.

Preserve Proper Names and Brand Styling

Automatic title conversion should not destroy intentional capitalization.

Examples can include:

YouTube

iPhone

eBay

OpenAI

ChatGPT

NASA

A good capitalization workflow separates title rules from recognized proper names and acronyms. If the converter cannot know whether an unfamiliar string is a brand, person, product, scientific term, or ordinary word, human review is still necessary.

When Should You Use a Title Case Converter?

Use it when you are preparing:

• Blog and article titles
• Academic paper titles
• Headings
• Book and chapter titles
• Song and album titles
• Film and television titles
• Presentation headings
• News and magazine composition titles
• Legal headings and source titles
• Medical or scientific titles where title case is required
• Email or marketing headings that follow an editorial style

The converter is most valuable when the title contains several small words and you do not want to guess which ones should be capitalized.

Frequently Asked Questions

Is title case grammatically required?

No. Title case is an editorial convention. Sentence case is also correct in many contexts. Use the style required by your publication, school, employer, or project.

Why does the same title change between Chicago and MLA?

The styles use different rules for some minor words, especially prepositions and compounds. The difference can be intentional even when both results are correct within their own systems.

Should every word with four letters be capitalized?

Not in every style. APA and AP use important length based rules. Chicago 18 uses a five letter threshold for prepositions. MLA treats prepositions differently.

Can I use title case for an entire paragraph?

You technically can, but title case is intended for titles and headings rather than ordinary prose. For paragraphs, sentence case is normally easier to read.
