What case conversions are supported?
We support all major case types: uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, and alternating case.
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (e.g., “camelCase”), while PascalCase starts with an uppercase letter (e.g., “PascalCase”). Both join words without spaces.

Yes! After loading the page once, you can use the case converter offline. All processing happens locally in your browser.
What is alternating case?
Alternating case alternates between uppercase and lowercase letters (e.g., “AlTeRnAtInG cAsE”). This is sometimes called “sponge case” or “mocking text.”
