Slug Generator — Create Clean SEO-Friendly URL Slugs

This free slug generator turns any title into a clean, SEO-friendly URL slug — lowercase, hyphen-separated, and stripped of punctuation. It transliterates accented characters to their closest ASCII form (café becomes cafe) so the URL stays portable across systems, and keeps your primary keywords readable. Good slugs improve click-through from search results and are easier to share than opaque numeric IDs. Keep them short and stable, since changing a published slug breaks links. Everything runs in your browser, so your text is never uploaded.

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.

What makes a good URL slug

A slug is the human-readable tail of a URL — the my-first-post in /blog/my-first-post. Good slugs are lowercase, use hyphens (never underscores or spaces), strip punctuation, and contain the page's primary keywords. Search engines and people both read them, so a descriptive slug improves click-through from results and is easier to share or remember than an opaque numeric id.

Handling accents and other scripts

Characters like é, ñ or ü should be transliterated to their closest ASCII form (café → cafe) so the URL stays portable across systems that mangle non-ASCII bytes. Strip "stop words" (a, the, and) only if it keeps the slug readable — clarity beats brevity.

Keep them stable

Once a URL is published and indexed, changing its slug breaks every existing link and can lose accumulated search ranking. If you must change one, set up a 301 redirect from the old slug to the new. Keep slugs concise — roughly 3–5 meaningful words — since very long URLs get truncated in search snippets and shares.
