Free URL Slug Generator

What a URL slug is

A URL slug is the readable identifier at the end of a web address. In example.com/blog/url-slug-generator, the slug is url-slug-generator. It is the part you choose, and the part that tells a reader what the page contains before they click. Search engines show it in results, browsers show it in the address bar, and people paste it into messages — so it is a small piece of copy that gets read far more often than most teams assume.

What makes a slug good

Short, descriptive, lowercase, hyphen-separated, and containing the primary keyword. Google treats hyphens as word separators and underscores as word joiners, which is why ai-seo-tools is read as three words and ai_seo_tools may not be. Three to six words, or roughly 60 characters, is a practical target — long enough to be descriptive, short enough to survive being pasted into a chat window.

Avoid dates and numeric IDs unless you genuinely need them. A slug like 2026-03-guide-v2 ages the page the moment the year turns and forces a redirect when you refresh the content.

How this tool builds your slugs

Each line is folded from Unicode to plain ASCII, so “Cómo diseñar una página” becomes como-disenar-una-pagina rather than a percent-encoded mess. Ampersands expand to “and”, punctuation and emoji are removed, whitespace collapses to your chosen separator, and the result is trimmed to your character budget at a word boundary — never mid-word, because a slug cut to programmatic-se helps nobody.

It also flags duplicates across your batch, which is the failure that actually costs you something: two pages cannot share a URL, and discovering the collision after publishing means a redirect and a lost afternoon.
