What Is Slug Generator?

A slug generator is a tool that converts human-readable text into URL-friendly slugs by removing special characters, normalizing accented characters using the NFD Unicode normalization form, replacing spaces with a separator, and converting to lowercase. Developers and content creators use it to solve the problem of creating clean and readable URLs for web pages, which is crucial for search engine optimization (SEO) since good slugs include target keywords in the URL. For instance, when optimizing a blog post title like "Hello World! It's 2024" into a SEO slug, it becomes "hello-world-its-2024", making the link more readable and shareable.

This tool stands out due to its customization options, such as choosing between different separators like hyphens, underscores, or dots, which allows users to generate URL slugs that fit specific formatting requirements. Additionally, the force lowercase feature ensures consistency in the generated slugs, which is important for maintaining a uniform URL structure across a website. By using it, users can efficiently convert text to slug formats suitable for online platforms, eliminating the need to manually edit and validate each URL slug.

The tool's ability to process multiple lines of input at once makes it particularly useful as a bulk text to slug converter, allowing users to quickly generate url slugs for numerous web pages or files in one go. This functionality, combined with its ease of use and customizable output, positions it as a practical solution for creating readable and SEO-friendly URLs, making the process of how to create URL slugs straightforward and efficient.

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

Q What is a slug?
A slug is the URL-friendly version of a title or name, using only lowercase letters, numbers, and separators like hyphens.
Q Why 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.
Q How are accented characters handled?
Characters like é, ñ, ü are normalized to their ASCII equivalents: e, n, u.
Q What happens to special characters?
Special characters (!@#$%&* etc.) are removed entirely. Only letters, numbers, and the separator remain.
Q Is it safe to 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.
