Frequently asked questions

Does conversion leave my device?

No. Everything runs locally in your browser. Nothing is sent to a server.

What is the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (userName); PascalCase capitalizes every word segment (UserName). Both drop spaces and separators.

When should I use snake_case vs kebab-case?

snake_case (user_name) is common in databases and Python; kebab-case (user-name) is typical for URLs, CSS classes, and slugs. Use Slugify if you only need URL-safe kebab output.
