Convert any text into a clean, URL-friendly slug with customizable separators.
Type the title or phrase to convert into a URL slug.
See the lowercase, hyphenated slug generated automatically.

A headline, product name, or any phrase goes in; a URL-safe slug comes out: lowercased, punctuation stripped, spaces replaced with the separator you choose, a hyphen by default. The result is the kind of permalink you see as /blog/this-is-the-slug. The part users most often get wrong is what disappears: commas, apostrophes, and periods are deleted outright rather than converted, so 'Hello, World!' and 'Hello World' produce the same slug. Consecutive separators collapse and edges are trimmed, so slugs never start or end with a hyphen or contain a double one. Everything runs in your browser, so confidential titles are safe to paste.

Every character is lowercased, each space becomes the default hyphen separator, and the comma and exclamation mark are deleted rather than replaced, so the output is nine hyphen-joined tokens matching the nine words of the input.
Text is processed left to right in a fixed order: lowercase everything, fold runs of whitespace (spaces, tabs, newlines) into one separator, delete punctuation and symbols, merge any separators that ended up adjacent, then trim the ends. Only letters, digits, and the separator itself survive, which is why the output always looks uniform regardless of how messy the input was.
Accented letters are normally folded to their nearest plain equivalent, so 'Cafe' with an accent slugs as 'cafe' and 'Munchen' with an umlaut as 'munchen'. Scripts without a Latin equivalent are the unreliable part: Cyrillic or Greek may be transliterated or dropped depending on the converter, and CJK characters usually have no slug form, so heavy non-Latin input can come back empty or unreadable. Run a sample through before trusting it with non-English titles.
Slugs only allow letters, digits, and the separator, so every other character is dropped rather than converted. 'Don't stop.' becomes 'dont-stop', not 'don-t-stop'. If the result is ambiguous or unreadable, edit the source text so the words you want separated are separated by real spaces, then convert again.
For permalinks, hyphen. Google's URL guidance explicitly says to separate words with hyphens, not underscores, and hyphenated slugs are the near-universal CMS convention. Underscores are still valid in URLs and read fine, so they are reasonable for file names or identifiers where you do not want word boundaries implied. Above all, match whatever style your existing site uses.
