A URL slug generator turns a title or phrase into a clean, SEO-friendly permalink. Type your heading and it lowercases the text, transliterates accents like café to cafe, and replaces spaces and punctuation with a single hyphen, live in your browser. Options let you switch to underscores or drop stopwords for a shorter, keyword-led slug.

What makes a URL slug good for SEO
A strong slug follows five rules, and this generator applies them for you. Keep it short and keyword-led: three to five words is plenty, and staying under about 60 characters keeps the full URL visible in search results. Use lowercase only, because some servers treat uppercase and lowercase as different addresses and that splits your ranking signals across duplicate URLs. Separate words with hyphens. Transliterate accents to plain ASCII, so café becomes cafe, and drop special characters like question marks and ampersands that browsers have to escape. Optionally remove filler stopwords such as a, the and of to tighten the slug. The result is a permalink that reads clearly to a person and parses cleanly for a search engine.
Should URL slugs use hyphens or underscores?
Use hyphens. Google treats a hyphen as a word separator and an underscore as a word joiner, so learn-seo reads as two words, learn and seo, while learn_seo reads as one joined term. Google's Gary Illyes put it plainly: the search engine cannot easily segment words at an underscore, which is why it recommends dashes. That is why this tool defaults to hyphens and only offers underscores for systems that require them, such as certain file names or code identifiers. For a public web page or blog post, keep the hyphen.
Why you should not change a slug after publishing
Once a page is live, its slug is part of its identity: it is the link people have shared, the address other sites have linked to, and the URL search engines have indexed. Change it without a plan and every one of those links breaks into a 404, and the ranking equity the old URL earned is lost. If you truly must change a slug, set up a 301 redirect from the old URL to the new one so that visitors and search engines are forwarded automatically. The safest habit is to get the slug right before you publish, which is exactly what this tool is for.
Questions, answered
What is a URL slug?
A URL slug is the part of a web address that identifies a specific page, the readable text after the domain and any folder. In example.com/blog/url-slug-guide, the slug is url-slug-guide. A good slug is lowercase, uses hyphens between words, and describes the page in a few keywords, so both people and search engines can tell what the page is about from the link alone.
Should URL slugs use hyphens or underscores?
Use hyphens. Google treats hyphens as word separators and underscores as word joiners, so my-first-post reads as three separate words while my_first_post reads as one. Gary Illyes of Google has confirmed the search engine recommends dashes because it cannot easily split words at an underscore. Hyphens are the standard for web URLs. Reserve underscores for file names or code where a system requires them.
Should you remove stop words from a URL slug?
Removing stop words like a, the, and, of and to makes a slug shorter and more keyword-focused, and it is not a ranking factor either way, so it is safe to do. The one caveat is meaning: keep a stop word when dropping it changes the sense of the slug. For most titles, removing them gives a cleaner permalink. This tool makes it a toggle so you decide per slug.
How long should a URL slug be?
Keep it short: three to five words, and under about 60 characters so the full URL shows in search results without truncation. Backlinko's study of 11.8 million results found pages ranking first had URLs on average 9.2 characters shorter than those in tenth. Length itself is not a ranking factor, but a short, keyword-led slug is easier to read, share and click, which is what actually helps.
Does the URL slug matter for SEO?
Yes, but only a little as a direct signal. Google's John Mueller calls words in the URL a very very lightweight ranking factor, so a good slug will not carry a weak page. The real value is user experience: a clear, keyword-matching slug earns more clicks in search results and is easier to share, and it helps AI assistants understand and cite the page. Get it right, but do not over-optimize it.
Is this slug generator free and private?
Yes. There is no account, no email and no usage cap, and the whole transform runs in your browser with JavaScript, so your text is never uploaded, stored or logged. It keeps working offline once the page has loaded.
