URL Slug Generator

A URL slug is the human-readable portion of a URL that identifies a specific page — the10-ways-to-build-a-faster-website at the end of a blog post URL, or the wireless-over-ear-headphones at the end of a product page URL. A slug generator transforms a plain-English title into that URL-safe form: lowercase, hyphen-separated, free of punctuation, accents, and emoji. Content teams use slugs to give every page a clean, readable address that works with search engines and does not break when shared over email or SMS.

SEO value is real but modest. Google's algorithm reads keywords in the URL; a descriptive slug can nudge rankings for its primary term by a small amount, especially for long-tail searches. More importantly, slugs affect click-through rates. Users scanning a search results page are more likely to click a URL that describes the destination than one that ends in /post-12345. A clean slug is also immune to the ID churn that happens when content moves between CMSes.

The mechanics of a slug generator are simple but full of edge cases. Start with the raw title, lowercase it, strip punctuation, collapse whitespace to a single separator, transliterate accented characters (café → cafe) so the URL survives when someone types it on a phone keyboard without the accented key, and trim to a target length without chopping a word in half. Optional passes: drop stopwords (the, a, of) for conciseness, convert & to and, keep numbers as-is.

Hyphen vs. underscore. Google has officially treated the hyphen as a word-separator and the underscore as a word-joiner since at least 2005. In a URL, cat-dog reads as two terms; cat_dog reads as one. The hyphen is always the right choice for SEO slugs. Underscore is occasionally requested for internal tools, legacy systems, or programming-adjacent routes.

Stopwords are a judgement call. Dropping the from "The Ultimate Guide" turns the-ultimate-guide into ultimate-guide — cleaner, but slightly odd to read when the stopword carries meaning (as it does in The Beatles). The generator leaves stopwords in by default; flip the toggle when you want them stripped.

Length matters. Google has no hard URL length limit, but URLs over ~75 characters get truncated in SERPs with an ellipsis. Blog slugs typically target 40–60 characters; product slugs can run longer if they carry meaningful keywords. The generator defaults to 60 and prefers to break on word boundaries — if cutting at 60 would slice a word, it backs up to the previous hyphen.

Privacy note: slug generation is entirely browser-side, so drafts of sensitive article titles (embargoed announcements, confidential product launches) never leave your device.

1. Enter a title. Paste or type the blog title, product name, or phrase.
2. Pick a separator. Hyphen is the SEO default; underscore is occasionally required.
3. Toggle lowercase, transliterate, stopwords. Defaults cover most cases.
4. Set max length. 60 is a good blog default. 0 removes the limit.
5. Copy the slug. One click places the slug on your clipboard.

• Hyphen or underscore separator; lowercase toggle.
• Unicode transliteration: café → cafe, naïve → naive, Muñoz → Munoz.
• Optional stopword removal with a sensible English default list.
• Max-length trimming that prefers word boundaries.
• Live preview URL to visualise the final page address.
• All processing is browser-side — draft titles stay private.
