SEO URL Slug Generator
A URL slug generator converts a page title or phrase into the readable identifier that sits at the end of a web address, such as /best-aged-domains. A clean slug helps both search engines and people understand what a page is about before they open it, and getting it right at publish time avoids the messy redirects that follow when a sloppy URL has to be changed later.
This free, browser-based tool transliterates accented characters to plain ASCII, lowercases the text, removes punctuation and symbols, and joins the words with a hyphen or underscore. It can strip common stop words and trim the result to a maximum length on a word boundary, and every keystroke is processed locally so nothing typed into it is ever uploaded.
🔒 Private: everything runs in your browser. Nothing you paste is uploaded.
How to use the URL slug generator
Type a single title or paste a batch of titles, choose a separator and a length limit, and the cleaned slug appears instantly. The options below let the output match almost any CMS or routing convention.
Transliterate accents so every character is URL-safe
Characters outside the basic ASCII range, such as the accented letters in café or Müller, are legal in modern URLs but render as ugly percent-encoded sequences and break inconsistently across browsers and analytics tools. The generator decomposes each accented letter with Unicode normalization and strips the combining mark, so é becomes e and ü becomes u, while special cases like the German ß expand to ss. The result is a slug built entirely from letters, digits, and the separator, which every server and crawler reads the same way.
Decide whether to strip stop words for shorter slugs
Short words like a, the, of, and in carry little meaning in a URL, so removing them can make a slug tighter and more keyword-focused. Toggle stop-word stripping on to drop them as whole words only, which means android keeps its embedded and. The tool will not reduce a slug to nothing: if a phrase is built entirely from stop words, the original words are kept. Whether to strip them is a judgement call, since a slightly longer slug that reads naturally is often clearer than an aggressively trimmed one.
Trim to length on a word boundary, never mid-word
Long slugs are harder to read, get truncated in search snippets, and look spammy when stuffed with every word from a headline. Set a maximum length and the generator cuts the slug back to the last complete word that fits, so a 60-character limit never leaves a half-finished word dangling at the end. The default 60-character target reflects common practice for readable, shareable URLs. Batch mode applies the same rules to a whole list at once and flags any duplicate slugs, since two pages competing for the same URL is a problem worth catching before launch.
URL slug generator frequently asked questions
Q1What is a URL slug?
A slug is the human-readable part of a web address that identifies a specific page, usually the words after the final slash. For a page titled “Best Aged Domains,” a typical slug is best-aged-domains. Slugs use lowercase letters, digits, and hyphens so that both search engines and people can read the URL and guess what the page covers before clicking it.
Q2Should a URL slug use hyphens or underscores?
Hyphens are the standard choice. Search engines treat a hyphen as a word separator, so best-aged-domains is read as three distinct words, while an underscore can join them into a single token. This tool defaults to hyphens and keeps the underscore option only for systems that specifically require it, such as certain file paths or legacy routing conventions.
Q3Does this slug generator send my titles to a server?
No. The entire transform runs in your browser with client-side JavaScript, so the titles you type or paste are never uploaded, logged, or stored anywhere. The tool keeps working even with the network disconnected once the page has loaded, which makes it safe to use for unpublished pages, internal projects, or confidential content.
Q4How long should an SEO-friendly slug be?
Shorter is generally better. A slug under about 60 characters stays fully visible in search snippets and is easy to share, which is why this tool defaults to a 60-character limit. There is no hard penalty for a longer slug, but trimming to the few words that actually describe the page tends to read better than carrying an entire headline.
Q5Why remove accents and special characters from a slug?
Accented and non-ASCII characters are technically allowed in URLs but get percent-encoded into long, unreadable sequences and behave inconsistently across browsers, email clients, and analytics. Converting them to plain ASCII equivalents keeps the slug clean and predictable. This tool transliterates accents to their closest letters and removes any character that is not a letter, digit, or the chosen separator.
