FAQ
What is the difference between camelCase and snake_case?
camelCase joins words with no spaces and capitalizes each word after the first (myVariable). snake_case uses lowercase words joined by underscores (my_variable). camelCase is common in JavaScript; snake_case is common in Python and Ruby.
Is my text uploaded anywhere?
No — all conversion happens in your browser. Your text never leaves your device.
Which case should I use for URLs?
kebab-case (lowercase words joined by hyphens, like my-page-title) is the safe, readable choice for URLs and CSS class names.
