Slug generator

Turn any title or phrase into a clean, URL-friendly slug. Handles accents, special characters, and spaces.

Slug

How slug generation works

A URL slug is the human-readable, URL-safe part of a web address that identifies a specific page — for example, /tools/slug-generator. Good slugs are lowercase, use hyphens as word separators, contain only alphanumeric characters, and omit stop words and special characters.

This generator applies the following transformations in order: convert to lowercase, replace accented characters with ASCII equivalents (é → e, ü → u, ñ → n), remove all characters except letters, digits, spaces, and hyphens, replace spaces and underscores with hyphens, collapse multiple consecutive hyphens into one, and trim leading/trailing hyphens. For example, "Hello World! My Article #1" becomes hello-world-my-article-1. Slugs matter for SEO: descriptive, keyword-rich slugs help search engines understand page content and are more shareable. Avoid auto-generated numeric slugs (/post/12345) when possible — they carry no semantic value for users or crawlers.

Frequently asked questions

What is a URL slug?

A URL slug is the part of a URL that identifies a specific page in a readable way — typically the last segment after the final slash. For example, in 'tulzu.com/tools/slug-generator', the slug is 'slug-generator'. Slugs use only lowercase letters, numbers, and hyphens.

Why are URL slugs important for SEO?

Descriptive slugs help search engines understand what a page is about, can improve click-through rates from search results (users see the URL in the snippet), and are more shareable. Pages with keyword-relevant slugs generally rank slightly better than those with numeric or auto-generated IDs.

Should slugs use hyphens or underscores?

Hyphens are strongly preferred. Google treats hyphens as word separators (so 'slug-generator' is read as 'slug generator'), while underscores are treated as connectors ('slug_generator' is read as 'sluggenerator'). All major web frameworks and CMS platforms default to hyphens.

What characters are removed from slugs?

Slugs retain only lowercase letters (a–z), digits (0–9), and hyphens. Everything else is removed or transformed: uppercase letters are lowercased, spaces become hyphens, accented characters are converted to their ASCII base (é → e), and all other special characters including punctuation are stripped.
