How do I change text to Title Case?
Paste your text, then click Title Case. Each word gets a capital letter, except short function words (a, an, the, and, but, or, nor, for, so, yet, at, by, in, of, on, to, up, as, if, per, via, vs), which stay lower case unless they are the first or last word. That matches the common English headline convention.
The eight case styles
| Style | Example | Typical use |
|---|---|---|
| UPPER CASE | THE QUICK GUIDE | Warnings, acronyms, short labels |
| lower case | the quick guide | Tags, normalising text |
| Title Case | The Quick Guide to Writing | Headlines, book and essay titles |
| Sentence case | The quick guide to writing. | Normal sentences, fixing CAPS LOCK |
| camelCase | theQuickGuide | Variable and function names |
| snake_case | the_quick_guide | Database columns, Python names |
| kebab-case | the-quick-guide | URLs and file names |
| aLtErNaTe | tHe qUiCk gUiDe | Memes and informal emphasis |
Title Case is a style choice, not a single rule
Different style guides capitalise titles differently. APA, MLA, Chicago and AP disagree about prepositions of four or five letters, hyphenated words and words after a colon. The converter applies one simple, widely used rule: short function words stay lower case, and everything else gets a capital letter. Use it as a first pass and check the result against the guide you must follow, especially for formal papers, where a stray lower-case or upper-case word can cost marks.
Proper nouns and acronyms are also not recognised. The tool lower-cases text before applying Title Case, so "NASA" becomes "Nasa" and you need to fix it by hand. The same applies to Sentence case and the names of people and places.
Sentence case and CAPS LOCK
If you typed a paragraph with CAPS LOCK on, paste it and choose Sentence case. The text is lower-cased first, then the first letter after each full stop, exclamation mark, question mark or line break is capitalised. Then fix names and the pronoun "I" manually.
Code-style formats
camelCase, snake_case and kebab-case remove spaces and punctuation and join the words. They are handy for naming things, but check the result against your project's conventions. If you need a URL slug from a title, the Slug Generator is a better fit because it also handles accents and symbols.
After converting, run a Grammar Checker pass, or clean stray spacing with the Text Cleaner.
