URL Slug Generator

Turn a page title into a clean URL slug: lowercase, hyphenated, accents folded, with an optional stopword filter and a live length check.

SerpPrism's URL Slug Generator is a free online tool that turns a page title into a clean, copy-ready URL slug: lowercase, hyphen-separated, with accents folded to plain ASCII and punctuation removed. There is no sign-up and it runs entirely in your browser. An optional filter drops common stopwords, and an optional length cap trims the slug at a word boundary instead of cutting a word in half. It is for anyone publishing a page who wants the URL decided deliberately — short, readable and stable — rather than whatever a CMS auto-generates from the headline. Type the title, copy the slug, and watch the character count as you go.

How to use it

1. Type or paste the page title exactly as it will appear on the page.
2. Choose whether to drop stopwords, and whether to cap the length — the slug rebuilds instantly.
3. Copy the slug into your CMS. Once the page is published and linked, treat the slug as permanent.

What makes a slug good

A good slug describes the page in a few words, in lowercase, with hyphens between words. Hyphens matter: Google treats a hyphen as a word separator and an underscore as a joiner, so url-slug reads as two words and url_slug reads as one long one. Dates, session IDs and file extensions do not belong in a slug unless the page is genuinely about that date.

Our guide to how long a URL slug should be works through the trade-offs with real examples, including when a longer slug is the honest choice. The short version: three to five words usually say enough, and the slug should match the title's meaning without copying every word of it.

Should you remove stopwords?

Sometimes. Dropping 'a', 'the' and 'of' almost never changes what a slug means, and it buys back characters. But stopword lists are blunt: 'how' and 'what' are function words that also carry search intent, and a slug stripped of them can end up describing a different query than the page answers.

That is why the filter here is off by default and conservative when on. Compare both versions before you choose. The right question is not 'is this word a stopword' but 'would a reader still know what this page is from the slug alone'.

Changing a slug after publishing

A new slug is a new URL. Every link, bookmark and search result pointing at the old one breaks unless you redirect it, one-to-one, with a 301 to the new address. Sites accumulate redirect chains by changing slugs casually and redirecting in bulk to the homepage, which helps nobody.

So decide the slug before the page goes live, while changing it is still free. If you must change one later, redirect that exact URL to its replacement and update your internal links to point at the new address directly.
