A slug is the URL-friendly version of a string: lowercase, hyphenated, with special characters and accents stripped. "Hello World!" becomes "hello-world". Slugs are used in URLs, filenames, and database keys.

How does the tool handle non-ASCII characters?

Accented characters are transliterated to their closest ASCII equivalent (é to e, ü to u, ñ to n). Cyrillic, Chinese, and Arabic characters can be transliterated where standard mappings exist; otherwise they are stripped or replaced with placeholders.

Clean slugs are more readable, more shareable, and slightly better for SEO. They also avoid URL-encoding issues when paths contain spaces or special characters.

Can I customize the separator?

Yes. The default separator is hyphen (-) which is the SEO standard, but you can switch to underscore (_) or other characters. Hyphens are recommended unless you have a specific reason to use something else.

Is the conversion done locally?

Yes. Slug generation runs entirely in your browser. Inputs and outputs never leave your machine.
