URL Slug Generator Online

A URL slug is the human-readable, URL-safe portion of a web address that identifies a page — for example, "my-blog-post" in example.com/blog/my-blog-post. Well-formed slugs are lowercase, use hyphens as word separators, contain only alphanumeric characters, and omit special characters and accents. Good slugs improve readability, click-through rates, and SEO because search engines use them as ranking signals.

This tool implements the standard slug generation pipeline: Unicode NFD normalisation to decompose accented characters (e.g. é becomes e + combining accent), removal of the combining diacritical marks, replacement of all non-alphanumeric sequences with the chosen separator, and trimming of leading and trailing separators. The result is compatible with WordPress, Drupal, Ghost, Jekyll, and virtually any CMS or web framework that uses slugs.

The choice of separator matters for SEO: Google Search treats hyphens as word separators — so "machine-learning" is understood as two words — while underscores are treated as word connectors, making "machine_learning" a single compound token. For maximum SEO benefit, hyphens are strongly recommended. Underscores remain useful when matching code identifier conventions or when slugs will be used in programming contexts.
