Frequently Asked Questions
Does it preserve punctuation?
For uppercase, lowercase, title, and sentence case, punctuation is preserved. For camelCase, PascalCase, snake_case, and kebab-case, non-alphanumeric characters are treated as word separators and removed from the output.
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (helloWorld). PascalCase starts every word with an uppercase letter (HelloWorld).
What is Title Case?
Title Case capitalises the first letter of every word — for example, "The Quick Brown Fox". It is commonly used for headings, article titles, and product names.
Is my text sent to a server?
No. All conversion runs in your browser. Nothing is uploaded or stored.
