Title Case Converter
Format headlines, blog titles, and book titles into proper Title Case capitalization.
Professional Title Case & Headline Capitalization Tool
Headlines, book titles, email subject lines, and blog banners carry significant visual weight. However, standard headline capitalization rules are notoriously tricky: major words must be capitalized, while minor articles, short prepositions, and coordinating conjunctions must remain lowercase unless they begin or end the title. Manual capitalization often leads to inconsistent formatting across publications.
ToolQix Title Case Converter automates headline capitalization according to established editorial standards (AP Stylebook and Chicago Manual of Style). It accurately identifies minor prepositions and conjunctions, applies capitalization rules across multiple lines, and allows you to format individual titles or entire bibliographies in seconds.
Grammatical Rule Engine & Boundary Word Evaluation
The Title Case algorithm splits strings into word tokens and cross-references them against an editorial dictionary of minor words (a, an, the, and, but, or, for, nor, in, to, of, at, by, up, off, on). Minor words under four letters are kept lowercase, but the first and last words of the title are always capitalized regardless of their part of speech.

- Keep prepositions with four or more letters capitalized under Chicago Style (e.g., 'With', 'From', 'About', 'Between').
- Do not capitalize hyphenated second elements unless they are proper nouns or major words (e.g., 'State-of-the-Art').
- Use Title Case for main headers, but Sentence case for body subheadings to improve readability.

FAQs About Title Case Converter
Which words stay lowercase in Title Case?
Articles ('a', 'an', 'the'), coordinating conjunctions ('and', 'but', 'for', 'nor', 'or'), and short prepositions under four letters ('in', 'to', 'of', 'at', 'by', 'up', 'off', 'on') remain lowercase unless they are the first or last word of the title.
Should short verbs like 'is' and 'be' be capitalized?
Yes! A common grammatical mistake is lowercasing 'is' or 'be' because they have two letters. However, verbs are always capitalized in Title Case regardless of length.
How does the tool handle subtitles after a colon?
The algorithm recognizes colons, em-dashes, and question marks as major structural boundaries and automatically capitalizes the first word of the subsequent subtitle.
What is the difference between AP Style and Chicago Style title capitalization?
AP Style capitalizes all words with four or more letters (including prepositions like 'with' and 'from'). Chicago Style focuses on parts of speech, keeping all prepositions lowercase regardless of length unless they are stressed or part of a phrasal verb.
