Slug Generator

Key takeaways

• Diacritics transliterate (café → cafe) instead of disappearing
• “&” becomes “and”; apostrophes drop without splitting the word
• One input line = one slug — paste whole headline lists
• Hyphen or underscore separators, generated locally

What is a URL slug?

A slug is the human-readable part of a URL path that identifies a page — lowercase words separated by hyphens, like /blog/how-to-format-json.

This tool normalizes Unicode (é → e), lowercases, converts “&” to “and”, removes apostrophes without splitting words (it's → its), and collapses every other non-alphanumeric run into a single separator. Each input line becomes one slug, so a pasted list of headlines converts in a single run.

Features

• Unicode transliteration

  NFKD normalization strips accents: “Über café” → “uber-cafe”.

• Batch mode

  Every input line becomes its own slug — paste headline lists.

• Sensible punctuation rules

  “&” → “and”, apostrophes drop cleanly, separators never double up.

• Separator choice

  Hyphens by default (SEO convention) or underscores when required.

How it works

1. 1

   Paste titles

   One per line — headlines, product names, doc titles.

2. 2

   Generate

   Each line normalizes, lowercases, and joins with your separator.

3. 3

   Copy into your CMS

   Use the output directly as URL paths or filenames.

Example walkthroughs

• Accents and punctuation

  Produces hello-world-its-great-and-fun — transliterated and collapsed.

  Héllo, Wörld — It's Great & Fun!

• Batch of headlines

Use cases

• CMS and blog URLs

  Generate consistent slugs for posts when your CMS's auto-slug is unreliable.

• File and asset names

  Create safe, lowercase names for uploads and static assets from display titles.

Code snippets

• Slugify in JS

  js

  The core normalization pipeline this tool applies per line.

  const slug = "Héllo, Wörld!"
    .normalize("NFKD").replace(/[\u0300-\u036f]/g, "")
    .toLowerCase()
    .replace(/[^a-z0-9]+/g, "-")
    .replace(/^-|-$/g, "");
  // "hello-world"

Common errors

• Accented characters vanished

  Cause: Naive slugifiers delete non-ASCII instead of transliterating.

  Fix: This tool NFKD-normalizes first, so “café” keeps its “e”.

• Double hyphens in the slug

  Cause: Punctuation next to spaces produced two separators in a row.

  Fix: Separator runs collapse to one here; re-generate if you hand-edited.

About Slug Generator

Slug Generator turns titles, headlines, and product names into the lowercase, hyphen-separated strings that belong in URLs. Paste one title or a whole list — each line converts to its own slug, so preparing a content calendar or a batch of product URLs is a single operation.

A good slug is more than “no spaces”. Search engines treat hyphens as word separators (underscores historically not), accented characters need transliteration rather than deletion so “café” stays readable as “cafe”, and stray punctuation — quotes, commas, em dashes — must collapse cleanly instead of leaving double hyphens. This tool applies those rules in one pass.

The details are opinionated on purpose: “&” becomes the word “and” because “terms-and-conditions” reads better than “terms-conditions”; apostrophes are removed without splitting, so “it's” becomes “its” rather than “it-s”; and repeated separators collapse, so “Part 1 — Setup” yields “part-1-setup”, not “part-1--setup”.

Slugification runs entirely in your browser. Unpublished titles are still confidential product information for many teams, so nothing is sent anywhere — consistent with the client-side privacy model across Toolverse by RS. When your goal is a code identifier rather than a URL, Case Converter's kebab-case target is the sibling tool.

Best practice: keep slugs short (3–6 words), drop stop words when they add no meaning, and never change a published slug without a redirect — the cleanest slug is not worth a broken link.
