What Is Slug Generator?

A slug generator converts human-readable text into URL-friendly slugs by removing special characters, normalizing accented characters, replacing spaces with a separator (typically hyphens), and converting to lowercase. Slugs are used in website URLs, file names, and identifiers where only URL-safe characters are allowed. For example, "Hello World! It's 2024" becomes "hello-world-its-2024". Good slugs improve SEO by including keywords in the URL and make links more readable and shareable.

Common Use Cases

Technical Guide

Slug generation follows these steps: (1) Normalize Unicode using NFD to decompose accented characters into base letter + combining mark, then remove combining marks (\u0300-\u036f). (2) Remove all non-alphanumeric characters except spaces and hyphens. (3) Trim whitespace. (4) Replace spaces with the chosen separator. (5) Collapse consecutive separators to a single separator. (6) Convert to lowercase (optional but recommended). This produces URL-safe strings that preserve the essence of the original text while being safe for use in URLs, file systems, and identifiers.

Tips & Best Practices

  • 1
    Hyphens are preferred over underscores for SEO — Google treats hyphens as word separators
  • 2
    Keep slugs short and descriptive — remove stop words like "the", "and", "of"
  • 3
    Accented characters are automatically normalized: "café" → "cafe"
  • 4
    Use one text per line to generate multiple slugs at once
  • 5
    Avoid changing slugs after publishing — it breaks existing links and SEO

Frequently Asked Questions

QWhat is a slug?
A slug is the URL-friendly version of a title or name, using only lowercase letters, numbers, and separators like hyphens.
QWhy are hyphens preferred over underscores in URLs?
Google treats hyphens as word separators but not underscores. "web-development" is read as two words; "web_development" as one.
QHow are accented characters handled?
Characters like é, ñ, ü are normalized to their ASCII equivalents: e, n, u.
QWhat happens to special characters?
Special characters (!@#$%&* etc.) are removed entirely. Only letters, numbers, and the separator remain.
QShould I change a slug after publishing?
Generally no — changing slugs breaks existing links and can negatively impact SEO. Set up redirects if you must change them.
