FAQ

What is param-case or kebab-case?

Param-case (or kebab-case) is a naming style where words are separated by hyphens and all letters are lowercase, such as 'my-page-title'. This converter handles the lowercase part; you can replace spaces with hyphens afterward if needed.

Can I use this for SEO slugs?

Yes, lowercase text is the foundation of SEO-friendly URLs. Convert your headings or titles to lowercase first, then replace spaces with hyphens.

Is there a limit to text length?

No, you can paste as much text as you need. The output will be fully lowercase.

Does it handle special characters?

It converts all uppercase letters to lowercase while preserving the rest of the characters. For URL-safe output, consider URL encoding separately.
