Case converter: camelCase, snake_case, kebab-case and slugs
Convert text to UPPERCASE, lowercase, Title Case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and URL slugs, all at once.
How it works
Type or paste text and you will see every variant at once, each with its own copy button. Useful for naming variables, database columns, CSS classes or files.
The slug removes accents and punctuation and joins words with hyphens, the ideal format for friendly, SEO-ready URLs (for example, "How to Design my Website?" becomes "how-to-design-my-website").
Frequently asked questions
What are camelCase and snake_case?
camelCase joins words capitalizing each one except the first (userName). snake_case joins them in lowercase with underscores (user_name).
Why do slugs have no accents?
URLs with accents get encoded as %C3%B3 and become unreadable when shared. An accent-free slug is cleaner and easier to remember.
