Free URL Slug Generator

A slug is the human-readable part of a URL that identifies a specific page — the hello-world in example.com/blog/hello-world. It's the bit you actually choose when you publish something, as opposed to the domain and folder structure around it. This tool takes any text — a blog title, a product name, a heading — and turns it into a clean, web-safe slug you can paste straight into your CMS, framework route, or link.

It matters for two audiences at once. For people, a readable slug is a preview of the page: /blog/how-to-make-cold-brew tells you exactly what you're about to click, which builds trust and lifts click-through both in search results and when the link is shared in a chat or email. For search engines, the words in the slug are a small but real relevance signal and, more importantly, a clean stable URL is easy to crawl and link to. The opposite — /post?id=48213&ref=xy — tells a reader nothing, looks sketchy when pasted, and is a pain to remember or type. A good slug is the cheapest bit of polish a page can have.

Turning a title into a safe slug is a pipeline of small, deliberate steps, and this tool runs them in order as you type. First it lowercases everything, because URLs are effectively case-sensitive on many servers and mixed-case slugs cause confusing duplicate-URL problems. Then it handles accents: using Unicode NFD normalization it decomposes accented letters into a base letter plus a combining mark, then strips the marks — so café becomes cafe, niño becomes nino, über becomes uber. That keeps the slug in plain ASCII, which is the most compatible across servers, browsers, and the places URLs get copied.

Next it removes characters that don't belong in a clean URL — punctuation, symbols, brackets, currency signs — so Price: $50 (50% off!) collapses to price-50-50-off. Spaces become your chosen separator, runs of separators are collapsed to a single one, and any separator left dangling at the start or end is trimmed. The result is a tidy, predictable string with no double-hyphens, no leading or trailing punctuation, and nothing a URL parser will choke on. Everything updates live, so you can watch a messy title resolve into a clean slug character by character and tweak the input if you don't like the result.

The separator is not just cosmetic, and the default — the hyphen — is the default for a real reason. Search engines treat hyphens as word separators, so cold-brew-coffee is read as three distinct words, exactly as intended. Underscores are historically treated as word joiners by some crawlers, meaning cold_brew_coffeecould be read as one long token; underscores are common in code and filenames but are the weaker choice for a public URL slug. For almost every web page, the hyphen is the right pick, and it's why it's selected out of the box.

The underscore and dot options exist because slugs aren't only for blog URLs. Underscores suit filenames, code identifiers, and database keys where that convention is expected. Dots show up in versioned identifiers, some file naming schemes, and certain routing setups. Pick the one that matches where the slug is going rather than defaulting blindly — but if the answer is "a page on my website," use the hyphen. (One note on the dot option: because a dot is a special character in the pattern-matching that cleans your text, the generator escapes it internally so it's treated literally — otherwise it would quietly trim the first and last characters of your slug. You just get a correct dotted slug.)

The optional max-length limit trims the slug to a set number of characters (and cleans up any separator left hanging at the cut). It's there because long slugs are worse slugs. A slug built from a full sentence — the-10-best-ways-to-make-cold-brew-coffee-at-home-this-summer — is unwieldy to read, gets truncated with an ellipsis in search results, and is annoying to share. Trimming to the few words that carry the meaning — cold-brew-at-home — is almost always cleaner and just as descriptive.

A good habit is to drop the filler your title needs but your URL doesn't: articles like "the" and "a", connecting words, and marketing fluff. The slug doesn't need to match the headline word-for-word; it needs to capture the topic in the fewest clear words. Set a modest max length, or just edit the input down before you copy, and you'll end up with slugs that read well everywhere they appear. The character counter next to the output helps you judge this at a glance.

A few anti-patterns show up again and again. Dates and numbers you'll regret: baking 2024 or part-1 into a slug ties the URL to a moment; when the content is updated the following year, the slug either lies or forces a rename. Leave time-bound tokens out unless they're genuinely permanent. Stop-word soup: slugs stuffed with "the", "and", "of", "to" read worse and gain nothing — the cleanup here won't strip those automatically because sometimes they matter, so trim them in the input when they don't. Keyword stuffing: repeating your target phrase two or three times in the slug looks spammy to both readers and search engines and can hurt more than it helps; one clear phrase is enough.

Then there are the mechanical ones this tool handles for you but that break hand-typed slugs constantly: uppercase letters that create duplicate-URL confusion, spaces that turn into ugly %20encoding, accented or non-Latin characters that some systems mangle, and trailing punctuation that produces double separators. Because the generator lowercases, transliterates accents, strips symbols, and collapses separators automatically, you get a slug that avoids all of those without having to remember the rules. The value isn't just speed — it's consistency: every slug you produce follows the same clean convention, which keeps a whole site's URLs uniform instead of each page reflecting whoever typed it that day.

The blog-post URL is the classic case, but the same clean-identifier need turns up all over. E-commerce product pages live or die on readable slugs — /products/wireless-noise-cancelling-headphones beats /products/sku-88213for both shoppers and search. Documentation and help-centre articles use slugs as anchors people link to directly. Category and tag pages, landing pages, event pages, and author profiles all need a stable, descriptive path. Outside the browser entirely, the same slugified strings make good filenames, image names, database keys, CSS class names, and API route segments — anywhere you want a human-readable identifier that's safe to use in a path or a variable.

That breadth is exactly why the separator choice and the plain-ASCII output matter. A slug destined for a WordPress permalink wants hyphens; one destined for a Python variable or a filename might want underscores; a versioned asset might use dots. The tool gives you the same reliable normalization for all of them, so whether you're naming a page, a file, or a key, you get a clean lowercase, accent-free, separator-consistent string you can drop in without a second thought. Learning to reach for a slug in all these places — not just blog URLs — is a small habit that keeps names tidy across an entire project.

This is the mistake that actually hurts, so it's worth stating plainly. Once a page is published and its URL is out in the world — indexed by search engines, linked from other sites, saved in someone's bookmarks, shared in old messages — that slug is effectively a permanent address. Changing it later breaks every one of those links: visitors and crawlers hit a 404, and the accumulated search ranking of the old URL is lost. The clean slug you generate here is worth getting right beforeyou publish, precisely because it's expensive to change afterward.

If you genuinely must change a live slug — a rebrand, a fixed typo, a restructure — don't just swap it. Set up a 301 redirect from the old URL to the new one so existing links keep working and most of the ranking signal carries over. That's a server or CMS setting, not something a slug generator can do for you; this tool's job is the front half — giving you a clean, correct slug to commit to in the first place. Get it right up front and you rarely need the redirect at all. The small history list here helps while you're drafting a batch of pages, letting you generate and copy several slugs in a row without losing the earlier ones.

The whole slug pipeline — lowercasing, accent stripping, character cleanup, separator joining, length trimming — runs in your browser with plain JavaScript. Your titles are never sent anywhere to be processed; there is no server endpoint behind this tool, and it would keep working with your connection off. The recent-slugs history lives only in the current page session. For a tool whose input is often unpublished titles and product names, that local processing is a genuine advantage — nothing you type here becomes a request to a slug-generating server.

The honest caveat, the same one that applies to any tool on an ad-supported site: "the slug is generated locally" is true, but "the page contacts nothing" is not. Like every page here, it loads standard analytics and ads, which are ordinary web requests. So the accurate claim is the specific one — your text is processed in your browser and never transmitted for slug generation — rather than a blanket "100% private, nothing ever leaves." For turning a title into a clean URL, local processing is all the privacy the task needs.
