title case converter

How to use the title case converter

  1. Paste the text you want to convert into the input box.
  2. Pick a style: AP (journalism default), Chicago (academic/book titles), Wikipedia, or Simple (every word capitalized).
  3. For AP and Chicago, toggle 'Always cap first word' — keep it on unless you specifically want strict rules.
  4. Copy the primary output, or grab any of the 11 variants (UPPERCASE, lowercase, sentence case, camelCase, snake_case, kebab-case, CONSTANT_CASE) from the All Variants panel.

When to use it

Use AP style for blog posts, marketing copy, and news articles — it's the dominant convention on the web. Chicago fits book titles, academic papers, and long-form journalism. Wikipedia's rule works well for technical documentation headings. The programming cases (camel, snake, kebab, constant) are handy when renaming variables or converting a sentence into a slug-safe identifier. Alternative: titlecaseconverter.com covers AP and Chicago but doesn't bundle programming cases or the all-variants panel.

Example

Input: `the quick brown fox jumps over the lazy dog`

AP: `The Quick Brown Fox Jumps Over the Lazy Dog` · Chicago: `The Quick Brown Fox Jumps over the Lazy Dog` · camelCase: `theQuickBrownFoxJumpsOverTheLazyDog` · kebab-case: `the-quick-brown-fox-jumps-over-the-lazy-dog`.

Frequently asked questions

What is title case?
Title case capitalizes the first letter of most words but keeps short articles, conjunctions, and prepositions (a, an, the, and, in, of, to) lowercase unless they start or end the title.
AP vs Chicago — which title case style should I use?
AP style is the web and journalism default (shorter small-word list, simpler rules). Chicago is more traditional, used in books and academic writing — it lowercases more prepositions than AP.
Why is 'The' capitalized at the start of my title?
Title case always capitalizes the first word regardless of its length. 'Always cap first word' is on by default to enforce this — turn it off only if you want to test strict small-word behavior.
Can I convert text to camelCase or snake_case?
Yes. Pick 'camelCase', 'snake_case', 'kebab-case', or 'CONSTANT_CASE' in the style dropdown, or copy any of those variants from the 'All variants' panel.
Does the converter handle acronyms like NASA or API?
Not automatically — title case rules lowercase the whole word and recapitalize the first letter. If you need to preserve acronyms, fix them after conversion, or use Simple mode which doesn't lowercase anything.
Why does 'Over' stay capitalized in AP but not Chicago?
AP's small-word list is short — 'over' is not in it, so it gets capitalized. Chicago's longer list includes 'over', so it stays lowercase in the middle of a title.
