What is a URL slug?

A URL slug is the human-readable part of a web address that identifies a specific page — the hello-world-this-is-a-test in example.com/blog/hello-world-this-is-a-test. Good slugs are lowercase, accent-free, and use hyphens or underscores to separate words instead of spaces or special characters. This tool normalizes Unicode (é → e), strips punctuation, and collapses repeated separators so the result is clean and SEO-friendly. All processing happens locally in your browser.

Frequently Asked Questions

What is a URL slug?

A slug is the URL-friendly version of a title used as the last segment of a URL path. Example: 'My Favorite Tools 2024!' becomes 'my-favorite-tools-2024'. Slugs use only lowercase letters, digits, and hyphens.

Why are slugs lowercase and hyphen-separated?

Lowercase avoids case-sensitivity issues between servers. Hyphens are preferred over underscores because Google treats hyphens as word separators — better for SEO keyword matching in the URL.

How are accented and special characters handled?

Accented characters are transliterated to ASCII equivalents (é → e, ñ → n, ü → u). This ensures URL portability — not all systems and URL parsers handle multibyte characters in path segments correctly.

Can I use numbers in a slug?

Yes. Numbers are kept as-is (e.g. 'top-10-developer-tools'). The only restrictions: use a-z, 0-9, and hyphens only; avoid starting or ending with a hyphen; no consecutive double-hyphens.

Do slugs affect SEO ranking?

Yes, modestly. Keywords in slugs are a minor ranking signal. Keep slugs short (3–5 meaningful words), include the primary keyword near the start, and omit stop words (a, the, in) for the cleanest result.
