What is the Title Case Converter?

A title case converter capitalizes the major words in a headline or title while leaving selected articles, conjunctions, and prepositions lowercase. The first and last word—and the first word after a subtitle colon—are capitalized. Because AP, APA, Chicago, and MLA do not apply identical rules, this tool shows selectable presets and a four-style comparison. It can process one title per line, retain ALL-CAPS abbreviations such as NASA, preserve mixed-case brands such as iPhone, and enforce a custom list such as OpenAI. These are transparent rule-based approximations: software cannot always determine whether a word is a preposition, adverb, particle, or part of a proper name, so difficult titles still need editorial review.

How to Use the Title Case Converter

Enter one or more titles

Paste, type, or open a text file. Put each headline on a separate line; blank lines and the original list structure are retained.

Choose a capitalization preset

Select General, AP-style, Chicago-style, MLA-style, or APA-style. Decide whether existing acronyms and mixed-case brands should remain untouched, and add custom protected spellings.

Compare and verify

Review the main result and the four style previews. Copy the chosen title or download the complete list, then check names, phrasal verbs, hyphenated compounds, and publication-specific exceptions.

Frequently Asked Questions — Title Case Converter

What words are lowercase in title case?

Most systems lowercase articles such as a, an, and the; coordinating conjunctions such as and, but, and or; the infinitive marker to; and some prepositions. The exact preposition rule differs among style guides. First and last words remain capitalized.

What is the difference between title case and capitalizing every word?

Capitalizing every word produces The Art Of Writing A Clear Headline. Title case applies minor-word rules and commonly produces The Art of Writing a Clear Headline. The correct result depends on the chosen editorial style and how each word functions.

Does this implement the complete AP, APA, Chicago, or MLA manual?

No. The presets implement common mechanical capitalization patterns and are labelled style-like approximations. Complete manuals include grammatical and publication-specific exceptions that a short rule-based tool cannot reliably infer. Verify high-stakes or ambiguous titles against the current official guide.

Can it preserve NASA, iPhone, eBay, or OpenAI?

Yes. Keep acronym and mixed-case preservation enabled. Add any required spelling to Protected words, separated by commas, and the converter will output that spelling exactly when it encounters the word.

Can I convert multiple headlines at once?

Yes. Put one title on each line. Every non-empty line gets its own first- and last-word treatment, while blank lines remain in place. The download contains the entire converted list.

Is my draft uploaded?

No. Title conversion, comparisons, statistics, clipboard actions, and text-file export run in this browser. The tool does not autosave or transmit your titles to ilovetexts.com.
