Frequently Asked Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter: myVariableName. PascalCase starts with an uppercase letter: MyVariableName. PascalCase is also called UpperCamelCase.
What case format do URLs use?
URLs use kebab-case (lowercase with hyphens): my-article-title. This is better for SEO than using underscores or spaces (%20).
How do I convert a sentence to title case?
Paste the text and click "Title Case". The converter capitalises the first letter of each word. Note: prepositions and conjunctions (of, and, the) are kept lowercase in proper title case.
Can the case converter handle multiple paragraphs?
Yes. Paste any amount of text — the converter handles entire articles, not just single words.
