Online Title Case Converter: Free Capitalization Tool
Inconsistent headline capitalization can make well-written articles, research papers, and blog posts look unpolished. Different publishing standards—such as APA, AP, Chicago, and MLA—have specific rules regarding which words to capitalize in a title. Manually checking every preposition, conjunction, and hyphenated word takes time and leads to errors.
This Title Case Converter automatically formats your headlines, titles, and subheadings according to standard editorial guidelines. Paste your text, choose your desired style guide, and get accurate results instantly.
What is Title Case Converter?
A Title Case Converter is a simple online tool that automatically fixes the capitalization of your headlines and titles. Instead of guessing which words need capital letters, you just paste your text into the tool, and it does the work for you instantly.
It works by capitalizing the main, important words while keeping small connector words (like and, the, in, or of) lowercase—turning a messy title like “how to start a business in 2026” into a clean “How to Start a Business in 2026.” It’s a quick time-saver for anyone writing emails, blog posts, or website headings who wants their text to look neat and professional without memorizing strict grammar rules.
How to Use the Title Case Converter
Converting your text takes only a few simple steps:

- Choose Your Capitalization Style: Select the radio button corresponding to your target style guide (e.g., APA, AP, Chicago, MLA).

Frequently Asked Questions (FAQ)
1. What is the difference between Title Case and Sentence Case?
Title Case capitalizes the first letter of major words (nouns, pronouns, verbs, adjectives, adverbs), while keeping minor words (short prepositions, articles, coordinating conjunctions) lowercase. Sentence Case capitalizes only the first letter of the sentence and any proper nouns.
2. Why are short words like “is” and “be” capitalized in title case?
Words like “is”, “am”, “are”, and “be” are verbs. In almost all style guides (including AP, APA, MLA, and Chicago), all verbs are considered major words and must always be capitalized, regardless of their length.
3. Does AP Style capitalize 4-letter prepositions?
Yes. Associated Press (AP) style capitalizes all words with four or more letters. This means prepositions like With, From, Into, and Over are capitalized in AP style, but kept lowercase in Chicago style.
4. How does Chicago style handle long prepositions like “through” or “between”?
The Chicago Manual of Style lowercases all prepositions, regardless of their letter count, unless they are the first or last word of the title or used as an adverb/adjective.
5. What does the “Keep Words in All Caps” setting do?
When checked, this option prevents acronyms, abbreviations, and code snippets (such as SEO, USA, API, or COVID) from being converted into lower or mixed case when running the converter.
6. Can I format multiple headlines at the same time?
Yes. Check the Enable Multi-Line Input box, paste your list of headlines (one per line) into the top input box, and click Convert. Every line will be formatted according to your selected style guide simultaneously.
7. What are straight quotes vs. smart quotes?
Smart quotes (curly quotes “ ” or ‘ ’) are typographically styled quotes used in print. Straight quotes (" or ') are standard vertical quotation marks preferred in coding, plain text files, and web databases. The “Use Straight Quotes” option converts all curly quotes into standard straight quotes.
8. Why are prepositions at the end of a title always capitalized?
Under every major style guide (APA, AP, Chicago, MLA), the first and last words of a title are always capitalized, regardless of their word length or part of speech.
9. Which title case style should I use for blog posts and website content?
AP Style and Chicago Style are the two most common choices for online publications, blogs, and digital media. AP style is generally preferred for marketing copy and news articles, while Chicago is popular for long-form essays and books.
