Slug Generator — Clean, URL-Safe Slugs (Free, No Signup)

Q: Should a slug be lowercase?

Yes. URLs are case-sensitive after the domain, so /My-Post and /my-post are two different pages to a server. Lowercasing avoids accidental duplicates and is the near-universal convention.

Q: How long should a slug be?

Short enough to read at a glance — roughly 3 to 6 words. Very long slugs get truncated in search results and are awkward to share; a 50–60 character cap is a sensible default.

Q: Should a slug use a hyphen or an underscore?

A hyphen, for anything in a URL. Search engines split words on hyphens but not on underscores, so hyphens make each word individually findable.

Turn any title into a tidy, URL-safe slug. Choose the separator, case, accent handling and a length cap — the result updates live, entirely in your browser. Nothing you type is sent anywhere.

What is a URL slug?

A slug is the human-readable part of a URL that identifies a page — the my-first-post in example.com/blog/my-first-post. A good slug is lowercase, uses hyphens between words, contains only ASCII letters, numbers and hyphens, and stays short. It makes links readable, shareable, and a little friendlier to search engines than an opaque ?id=4815.

What this generator does

Transliterates accents — Crème Brûlée becomes creme-brulee, not cr-me-br-l-e. Most quick slugifiers just delete accented letters; this one folds them to their closest ASCII letter first.
Collapses punctuation and spaces into a single separator, then trims any leading or trailing separators.
Caps the length at a word boundary — it won't leave you with a slug chopped off mid-word or ending in a stray hyphen.
Lets you pick hyphen vs underscore and whether to lowercase.

Gotchas worth knowing

Hyphens beat underscores for the web. Google treats a hyphen as a word separator but an underscore as a word joiner — two_words can be read as one token. Use hyphens for page URLs; underscores are more of a filename habit.
Slugs should be unique. Two posts titled "Hello World" produce the same slug. Most systems append -2 or a short id to break the tie — this tool generates the base slug; your CMS handles collisions.
Don't change a published slug casually. The slug is part of the URL, so editing it breaks every existing link and bookmark unless you add a redirect.
Stop words are a style choice, not a rule. Dropping a / the / of shortens a slug, but it's optional — keep them if it hurts readability. This tool leaves your words intact so you stay in control.
Non-Latin scripts. Stripping accents works for Latin-based languages. Text in scripts with no ASCII equivalent (e.g. CJK) will be removed by the URL-safe filter — for those, keep a manually chosen slug.

Hyphen or underscore in a slug?

Hyphen, for anything that lives in a URL. Search engines split words on hyphens but not on underscores, so hyphens make each word individually findable.
