Overview
Introduction
Headlines, book titles, and article names follow a specific capitalization convention where small connector words stay lowercase while the meaningful words are capitalized.
Applying that rule consistently by hand across a long title is easy to get wrong, especially remembering that the first and last word are always capitalized regardless of their type.
What Is Title Case Converter?
A converter that applies standard English title-case rules: it capitalizes major words and lowercases a fixed list of minor words (articles, short conjunctions, and short prepositions), except when a minor word opens or closes the title.
It runs entirely client-side as part of this site's String Tools collection, so nothing you paste is ever uploaded to a server.
How Title Case Converter Works
The tool splits the input into words while preserving whitespace, checks each word against a fixed list of minor words, and lowercases it unless it's the first or last word of the input; every other word is capitalized.
The transformation happens synchronously in JavaScript the moment you type, with no network round trip involved.
When To Use Title Case Converter
Use it when formatting a blog post title, book title, or headline that needs to follow conventional title-casing rules rather than capitalizing every word.
It's a fast way to get correctly styled title case without memorizing or manually applying the minor-word exception list.
Often used alongside Case Converter and Proper Case Converter.
Features
Advantages
- Follows the standard convention of lowercasing minor words instead of capitalizing everything, matching how professionally edited titles are styled.
- Always capitalizes the first and last word, even when they'd otherwise be minor words.
- Preserves the original whitespace runs while re-casing, so a deliberately spaced or indented title keeps its layout intact.
Limitations
- The minor-word list is fixed and doesn't cover every style guide's exact exceptions (some guides also lowercase longer prepositions like 'with' or 'from').
- Hyphenated compound words are treated as a single token rather than title-casing each part separately.
Examples
Best Practices & Notes
Best Practices
- Review the result against your specific style guide (AP, Chicago, MLA) if you need an exact match, since minor-word lists vary slightly between them.
- Check hyphenated compounds afterwards, since the split is on whitespace and a hyphenated pair is handled as a single word.
- Re-capitalize proper nouns and acronyms by hand, because a minor word that happens to be part of a name is lowercased along with the rest.
Developer Notes
Word tokens are produced with `input.split(/(\s+)/)` to preserve original whitespace runs, then each non-whitespace token is checked against a `Set` of minor words (after stripping non-letters) and lowercased unless its index matches the first or last word-token index found in the input.
Title Case Converter Use Cases
- Formatting a blog post or article headline
- Styling a book or movie title for a bibliography or catalog entry
- Capitalizing a page or section heading consistently with editorial conventions
Common Mistakes
- Assuming every word gets capitalized; minor words in the middle of the title are deliberately kept lowercase.
- Expecting a hyphenated word to have each half capitalized independently.
Tips
- If your style guide also lowercases longer prepositions like 'with' or 'from', manually adjust those after conversion since they aren't in the default minor-word list.
- Minor words are only lowercased in the middle of a title, so a one- or two-word title always comes out fully capitalized.
