URL Slug Generator

A URL slug generator turns any sentence, blog title, or product name into a clean, search-engine-friendly slug in one click. The slug is the part of a URL that comes after the domain — the building-a-saas-mvp in yoursite.com/blog/building-a-saas-mvp. A good slug is short, lowercase, hyphen-separated, and free of special characters; it tells both human readers and Google what the page is about before they click. This free URL slug generator handles all the edge cases that break custom regex — Unicode accents, smart quotes, emoji, ampersands, and consecutive whitespace — so you ship clean, indexable URLs every time.

How this URL slug generator works

The slug generator runs a four-step pipeline entirely in your browser — your input never reaches a server. First, it NFKD-normalises the input to decompose accented characters (so café becomes cafe, not URL-encoded gibberish). Second, it transliterates smart quotes, em dashes, and ampersands to ASCII equivalents (& becomes and). Third, it lowercases the string and collapses any run of non-alphanumeric characters into a single hyphen. Fourth, it trims leading or trailing hyphens and clips the slug at a hyphen boundary so you never end up with a half-word like building-a-saas-mvp-platf. Every step is configurable via the options panel.

When you need a URL slug generator

You need a URL slug generator any time content goes live with a public URL — blog posts, landing pages, product detail pages, help-centre articles, course modules, podcast episodes, event pages, even feature flag names. Marketing and SEO teams use slug generators to keep every URL keyword-aligned with the title, since Google reads the slug as a ranking signal. CMS engineers use them inside content pipelines, where every new row needs a deterministic slug. Solo founders writing in Markdown reach for a slug generator the moment they realise My First Post — A 2026 Recap! pasted into a URL field stays exactly that way unless something normalises it.

Common slug mistakes this slug generator avoids

Most quick-and-dirty slug regex fails on three things. First, Unicode: stripping non-ASCII characters with [^a-z] deletes accented characters entirely instead of transliterating them, turning Über into an empty string. This URL slug generator NFKD-normalises first. Second, length: cutting at a fixed character count drops you mid-word; this tool trims at the nearest hyphen. Third, reserved characters: forgetting that &, ?, #, and % are URL-control characters causes the slug to break the URL itself once published. The generator escapes or removes all of them.

Frequently asked questions

What is a URL slug?

A URL slug is the human-readable identifier at the end of a page URL — the /about-us in yourdomain.com/about-us. Slugs help visitors and search engines understand what a page contains before they click. Well-formatted URL slugs improve click-through rate, indexability, and on-page SEO.

What characters can a URL slug contain?

Best practice is to limit URL slugs to lowercase ASCII letters (a-z), digits (0-9), and hyphens. Underscores work technically but Google recommends hyphens as word separators. Avoid spaces, special characters, accented characters (unless transliterated), and uppercase letters — they create encoding issues and weaker SEO signals.

How long should a URL slug be?

Keep URL slugs under 60 characters where possible. Google truncates long URLs in search results, and short, keyword-focused slugs typically outperform long ones in click-through rate. This URL slug generator defaults to 80 characters as the maximum but lets you set any value between 10 and 200.

Is this slug generator safe to use for confidential titles?

Yes. The slug generator runs entirely in your browser using JavaScript — your input is never transmitted to a server, logged, or stored. Sensitive product names, draft article titles, and internal project names stay on your device with no exception.
