Free URL Slug Generator — Clean Slugs Instantly

Q: What is a URL slug?

A URL slug is the human-readable part of a web address that identifies a specific page. In example.com/blog/how-to-bake-bread, the slug is how-to-bake-bread. Slugs use lowercase letters, numbers, and hyphens with no spaces or special characters.

Q: Should I use dashes or underscores in slugs?

Use dashes. Google treats hyphens as word separators, allowing each word to be indexed as an individual keyword. Underscores join words into a single token, which is less SEO-friendly.

Slug Generator Guide

What Is a URL Slug and Why Does It Matter?

SEO-friendly URLs: Clean slugs help search engines understand your page content. A slug like how-to-bake-sourdough-bread ranks better than page?id=4821.
CMS-ready: WordPress, Shopify, Ghost, and most modern CMS platforms expect dash-separated, lowercase slugs for post and product URLs.
Batch support: Paste a whole list of titles — one per line — and generate all slugs at once. Ideal for content migrations or planning editorial calendars.
100% private: All processing runs in your browser. Your titles are never sent to any server.
Completely free: No account required, no usage limits, no paywalls.

Understanding the Options

Separator

The separator replaces spaces and non-alphanumeric characters between words. The dash (-) is the web standard recommended by Google and used by most CMS platforms. The underscore (_) is common in Python and database identifiers. The dot (.) is used less frequently but appears in some legacy systems and file naming conventions.

Case

Lowercase is the default and the broadly accepted standard for URLs — it avoids duplicate-content issues caused by case-sensitive servers treating /My-Post and /my-post as different pages. Preserve keeps the original capitalisation, which is occasionally needed for internal identifiers or specific platform requirements.

Best Practices for URL Slugs

Keep slugs short: Aim for 3–5 meaningful words. Search engines truncate very long URLs in results, and shorter slugs are easier to share and remember.
Use dashes, not underscores: Google treats hyphens as word separators but underscores as word joiners. red-shoes is indexed as two keywords; red_shoes is one.
Remove stop words when possible: Words like "a", "the", "and", "of" add length without adding keyword value. Many SEOs trim them manually after generating the base slug.
Never change slugs after publishing: Once a URL is live and indexed, changing its slug breaks inbound links and loses any accumulated SEO equity unless you set up a 301 redirect.
Match the slug to your H1: Keeping the slug aligned with the page title sends consistent relevancy signals to search engines.

Frequently Asked Questions

What is a URL slug?

A URL slug is the part of a web address that identifies a specific page in a human-readable way. In example.com/blog/how-to-bake-bread, the slug is how-to-bake-bread. Slugs typically use lowercase letters, numbers, and hyphens, with no spaces or special characters.

Should I use dashes or underscores in slugs?

Use dashes. Google's John Mueller has confirmed that hyphens are treated as word separators, which allows each word to be indexed independently as a keyword. Underscores join words into a single token. For the best SEO results, stick with dashes unless your platform specifically requires underscores.

Does slug capitalisation affect SEO?

On case-sensitive servers (most Linux-based hosts), /My-Post and /my-post are two different URLs. This can cause duplicate content issues if both are accessible. Using all-lowercase slugs eliminates the problem entirely and is the industry standard.

Can I generate multiple slugs at once?

Yes. Paste multiple titles into the input, one per line, and click Generate. Each line produces its own slug. You can copy individual slugs or use the "Copy All" button to copy the entire batch to your clipboard.

How does the tool handle special characters and accents?

The generator uses the slugify library, which transliterates accented and non-ASCII characters to their closest ASCII equivalents before slugifying. For example, "Ångström" becomes "angstrom" and "café" becomes "cafe". Remaining special characters are stripped, keeping only letters, numbers, and the chosen separator.

Is my text stored or sent anywhere?

No. All slug generation happens entirely in your browser using JavaScript. Your titles are never sent to any server, stored in a database, or shared with any third party. You can safely paste confidential product names or unpublished article titles.
