What is a slug?

A slug is a URL-safe version of a string: only lowercase letters and digits, with spaces and special characters replaced by a separator character. Slugs are used in URLs, file names, and database keys to uniquely identify a resource without encoding problems.

Example: Hello World! This Is a Test 2024 → hello-world-this-is-a-test-2024

How this tool processes your text

  1. Transliteration: accented and non-ASCII characters are converted to their ASCII equivalents: é → e, ü → u, ñ → n, ç → c, and so on
  2. Lowercase: all characters are converted to lowercase
  3. Separator replacement: spaces and special characters are replaced with the chosen separator (hyphen, underscore, or dot)
  4. Cleanup: consecutive separators are collapsed to one; leading and trailing separators are removed

Which separator to choose?

  • Hyphen (-): the standard for URL paths. Google recommends hyphens for SEO-friendly URLs (/blog/hello-world).
  • Underscore (_): common for database column names, Python identifiers, and file names where hyphens are not allowed by convention.
  • Dot (.): used for domain-style notation or certain configuration file keys.

SEO and URL best practices

  • Keep slugs short, aim for 3-5 meaningful words
  • Include the primary keyword near the beginning
  • Avoid stop words (the, a, in, of) when they do not add meaning
  • Use hyphens as word separators, never spaces or underscores in URLs
  • Avoid changing slugs after publishing, broken links hurt SEO
