What characters are allowed in a slug?

URL slugs should only contain lowercase letters (a-z), numbers (0-9), and hyphens (-). This tool removes all other characters and converts spaces and underscores to hyphens.

How are accented characters handled?

Accented characters like é, ü, and ñ are normalized using Unicode NFD decomposition and then the accent marks are removed, resulting in e, u, and n. This produces ASCII-only slugs that work everywhere.

Can I use underscores instead of hyphens?

The tool defaults to hyphens, which are preferred by most SEO guidelines and search engines. Google recommends hyphens over underscores as word separators in URLs.
