Frequently Asked Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariable), while PascalCase starts uppercase (MyClass). Use camelCase for variables/methods and PascalCase for classes.
Which case format should I use for URLs?
Use kebab-case (words-with-hyphens). Google treats hyphens as word separators, making it best for SEO.
What is title case vs sentence case?
Title Case Capitalizes Each Word (for headlines), while Sentence case only capitalizes the first word (for body text).
Is my text stored anywhere?
No! All conversion happens in your browser. We never see, store, or transmit your text.
