About the Slug Generator

A clean, readable URL slug is a small detail with outsized SEO impact. The Slug Generator tool converts any headline or phrase into a URL-safe permalink string in real time: it strips accents and diacritics, replaces every run of non-alphanumeric characters with your chosen separator, and joins the remaining words together. A separator dropdown lets you pick between hyphens and underscores; a Lowercase switch normalizes case (on by default); and a Strip stopwords toggle removes filler words like the, of, and your so the slug stays keyword-dense. A Max length slider — adjustable from unlimited to 200 characters, defaulting to 80 — truncates long titles cleanly and trims any trailing separator so the result never ends with a dangling dash. Everything updates live as you type, and the finished slug can be copied or downloaded straight from the Slug output box. Content marketers, developers, and site owners use this URL slug generator to keep permalinks consistent, short, and keyword-focused across blog posts, product pages, and documentation — exactly what search engines prefer.

How to use the Slug Generator

  1. 1

    Type or paste your title into the Text input field; the slug preview updates as you type.

  2. 2

    Choose Hyphen ( - ) or Underscore ( _ ) from the Separator dropdown.

  3. 3

    Toggle Lowercase and Strip stopwords to match your URL convention.

  4. 4

    Drag the Max length slider to cap the slug length, or set it to 0 to see the infinity symbol for unlimited.

  5. 5

    Copy or download the finished slug from the Slug output box.

Common use cases

  • Turning blog headlines into clean permalink slugs.
  • Generating SEO-friendly URLs for product and category pages.
  • Preparing documentation filenames with consistent hyphenation.
  • Building short link identifiers for campaigns and tracking.
  • Converting accented titles into ASCII-safe URL tokens.
  • Enforcing a max-length slug convention across a content team.

Best practices

  • Default to hyphens for SEO-facing URLs and reserve underscores for code and filesystem names.
  • Keep slugs between 40 and 60 characters so they remain readable in search results and share previews.
  • Strip stopwords for content pages where keyword density matters, but keep them off for exact filenames.
  • Set Max length to your CMS limit so every slug you generate fits without manual trimming.
  • Write the title naturally first, then generate the slug from it rather than composing both by hand.

Tips

  • Keep slugs under 60 characters for the cleanest URLs; use the Max length slider to enforce the habit.
  • Toggle Strip stopwords for blog posts so the slug is keyword-dense rather than word-for-word with the title.
  • Pair the underscore separator with snake_case conventions in code repos where filenames and identifiers must match.
  • The preview is live — paste a full title and read the slug before you copy it anywhere.

Frequently asked questions

Hyphens are the established best practice: search engines interpret hyphens as word separators, so best-way-learn-typescript reads as five words, while underscores can be treated as joining characters. The tool defaults to Hyphen ( - ) for this reason, but you can switch to Underscore ( _ ) when your CMS, framework, or file-naming convention requires it.

It removes a fixed list of common English filler words — the, a, of, to, your, and similar — from the generated slug, leaving only the meaningful, keyword-dense words. This shortens URLs and concentrates their relevance. Stopword filtering is off by default so nothing is removed unless you opt in, and the preview updates live when you toggle it.

The slider caps the generated slug at anywhere from unlimited to 200 characters, defaulting to 80. If the slug would be longer, it is truncated to the limit and any trailing separator fragment is trimmed, so you never get a URL ending in a dangling dash. Set it to 0 to see an infinity symbol and disable the limit entirely.

It normalizes input with Unicode NFKD decomposition and strips combining diacritics, so Cómo becomes Como, café becomes cafe, and München becomes Munchen. This keeps slugs ASCII-safe and avoids percent-encoded characters in URLs while preserving the meaning of the original words.

Yes, with one caveat: non-Latin scripts such as Cyrillic, Chinese, or Arabic contain no A–Z characters, so their words are removed during the alphanumeric filtering step. Latin-script languages like Spanish, French, and German work fully after diacritic stripping, and the Lowercase switch handles their case-folding without issues.

Three transforms happen in order: diacritics are stripped, every run of non-alphanumeric characters is converted to word boundaries, and then your options — separator choice, lowercase, stopword removal, and max length — are applied. Punctuation like apostrophes and em dashes disappears, and numbers are kept. The result is a clean, predictable URL token.
