Slug Generator

Turn any title or string into a clean, URL-safe slug.

Slug

The Slug Generator converts any title, heading, or string into a clean, URL-safe slug. It lowercases the text, strips accents and punctuation, and joins the words with a hyphen or underscore — exactly what you want for a blog URL, a filename, or an anchor id. Everything runs locally in your browser.

  • Handles accents and Unicode by transliterating to ASCII
  • Collapses spaces and repeated separators automatically
  • Choose hyphen or underscore, and toggle lowercase
  • 100% private — nothing is uploaded

What Makes a Good Slug

A slug is the human-readable part of a URL — the my-blog-post in /blog/my-blog-post. Good slugs are lowercase, use hyphens between words, contain only letters, numbers and hyphens, and drop stop-words and punctuation. This tool applies those rules for you so your URLs stay clean, readable, and stable.

Why Slugs Matter for SEO

Search engines use the words in a URL as a ranking signal, and a clean, readable slug like /blog/json-vs-yaml tells both users and crawlers what the page is about before they even click. A slug full of numbers, session IDs, or unencoded special characters (/blog/post?id=8271&ref=%20x) carries none of that signal and looks untrustworthy in search results. Keeping slugs short, lowercase, and hyphenated is a small, low-effort SEO habit that pays off on every page you publish.

Where Slugs Are Used

  • Blog and CMS URLsGenerate the URL path from a post title so links are readable and SEO-friendly.
  • File and asset namesTurn a label into a safe filename with no spaces or special characters.
  • Anchor and element idsCreate stable id attributes for headings and in-page anchor links.
  • API resource keysDerive a predictable, URL-safe identifier from a display name.
  • Git branch namesTurn a ticket title into a clean, valid branch name with no spaces or special characters.

Frequently Asked Questions

Slugify is the process of converting a string into a URL-safe slug: lowercasing it, removing accents and special characters, and replacing spaces with a separator like a hyphen.

Yes. Accented letters like é or ü are transliterated to their closest ASCII equivalent (e, u) so the slug is fully URL-safe.

Hyphens are the web standard for URLs and are recommended for SEO. Underscores are common for filenames and some code contexts. You can pick either.

No. The slug is generated entirely in your browser with JavaScript. Nothing is sent to a server.

No — numbers are preserved. Only characters outside letters and numbers (spaces, punctuation, symbols) are replaced or removed.

It passes through unchanged, aside from lowercasing if that option is on — running an already-valid slug through the tool is safe and idempotent.
