Slug Generator
Free online URL slug generator. Turn any title, headline, or phrase into a clean, SEO-friendly URL slug — accented and Unicode characters are transliterated to plain ASCII (so “Café Münü” becomes cafe-munu), punctuation and emoji are stripped, and words are joined with a hyphen or underscore. Choose your separator, set an optional maximum length, and copy the slug with one click. No uploads, no sign-up, and your text never leaves your device.
ToolsSoup’s Slug Generator is a free online tool that turns any title, headline, or phrase into a clean, SEO-friendly URL slug. It transliterates accented and Unicode letters into plain ASCII, so “Café Münü” becomes cafe-munu and “São Paulo” becomes sao-paulo, then strips punctuation, symbols, and emoji, collapses runs of spaces and separators, lowercases everything, and joins the remaining words with a single hyphen or underscore. You can pick the separator and set an optional maximum length to keep slugs short, and the tool truncates on a word boundary so it never ends mid-word. Paste a blog title or product name, click the button, and you get a tidy, lowercase slug ready to drop straight into your URLs. Everything runs in your browser — there are no uploads, no sign-up, and no character limit, and your text never leaves your device.
What is a URL slug?
A URL slug is the human-readable part of a web address that identifies a specific page, usually the last segment of the path. In the address example.com/blog/how-to-bake-bread, the slug is how-to-bake-bread. A good slug is short, lowercase, made only of ASCII letters, numbers, and hyphens, and describes the page so both people and search engines can tell what it is about at a glance. Because raw titles contain spaces, capital letters, accents, and punctuation that do not belong in a clean URL, a slug generator converts a readable title into a safe, consistent slug you can use in your routes.
How to generate a URL slug
Creating an SEO-friendly slug takes just a few seconds:
- Type directly into the text box or paste the title or phrase you want to convert.
- Pick a separator — hyphen for URLs (recommended) or underscore.
- Optionally set a maximum length to keep the slug short; it will be trimmed on a word boundary.
- Click Generate slug to transliterate, clean, and lowercase the text.
- Click Copy result to copy the finished URL slug to your clipboard.
How accented and Unicode characters are handled
Real-world titles are full of accents, special letters, symbols, and emoji that are not safe or readable in a URL. This generator transliterates them to their closest ASCII equivalent so the meaning survives: é, è, and ê become e; ü becomes u; ñ becomes n; ß becomes ss; æ becomes ae; and ampersands and at signs become the words and and at. Anything that has no letter equivalent — punctuation, currency signs, and emoji — is removed, and the leftover words are joined with your chosen separator. The result is always lowercase, plain ASCII, and free of repeated or trailing separators.
Slug generator vs. kebab-case converter
Both produce lowercase, hyphen-joined text, but a slug generator does more than a kebab-case converter. A kebab-case converter focuses on splitting words — including camelCase and snake_case identifiers — and joining them with hyphens, which is great for class names and code. A slug generator is built for URLs: it also transliterates accents and Unicode to ASCII, strips emoji and punctuation, lets you choose a hyphen or underscore separator, and can cap the length. Use the slug generator when you need a clean, SEO-friendly page address; use the kebab-case converter when you are renaming variables, CSS classes, or files.
Why use this slug generator?
- Transliterates accented and Unicode characters to ASCII, so Café Münü becomes cafe-munu.
- Strips punctuation, symbols, and emoji, then collapses extra spaces and separators.
- Lets you choose a hyphen or underscore separator to match your URL or framework style.
- Optional maximum length trims slugs on a word boundary so they never end mid-word.
- Handles each line on its own, so you can turn a whole list of titles into slugs at once.
- Runs entirely in your browser with one-click copy — your text is never uploaded or stored.
Frequently asked questions
How do I generate a URL slug?
Paste your title or phrase into the box, choose a separator and an optional maximum length, and click Generate slug. The tool transliterates accents to ASCII, removes punctuation and emoji, lowercases the text, and joins the words with your separator. The SEO-friendly slug appears in the output box ready to copy.
What makes a slug SEO-friendly?
An SEO-friendly slug is short, lowercase, made of plain ASCII letters, numbers, and hyphens, and describes the page using a keyword or two. Search engines treat hyphens as word separators, so a slug like how-to-bake-bread reads clearly to both people and crawlers and helps the page rank for what it is about.
Does it convert accented or non-English characters?
Yes. The generator transliterates accented and Unicode letters to their closest ASCII equivalent, so Café Münü becomes cafe-munu and São Paulo becomes sao-paulo. Characters with no letter equivalent, such as punctuation, symbols, and emoji, are removed.
Should I use a hyphen or an underscore in a slug?
For URLs, use a hyphen. Search engines treat hyphens as word separators but tend to read underscores as joining words together, so word-one-word-two is clearer than word_one_word_two. Underscores are offered for cases where a framework or file system expects them.
Can I limit how long the slug is?
Yes. Enter a maximum length and the slug will be trimmed to fit, cutting on a word boundary so it never ends in the middle of a word or with a trailing separator. Leave the field empty or set it to zero for no limit.
How is this different from a kebab-case converter?
A kebab-case converter mainly splits words and joins them with hyphens. A slug generator goes further for URLs: it transliterates accents and Unicode to ASCII, strips emoji and punctuation, lets you pick a hyphen or underscore separator, and can cap the length — producing a clean, SEO-friendly page address.
Can I generate several slugs at once?
Yes. Each line is converted on its own, so you can paste a list of titles and get one URL slug per line in a single click.
Is my text private?
Absolutely. All conversion happens locally in your browser using JavaScript, so the text you enter is never sent to or stored on any server.
