Make a URL slug from a title. Accents are stripped, spaces become hyphens, and you can keep Chinese, Japanese or Korean characters.
A title like “Café au lait — Größe” should not be pasted raw into a path. Spaces, punctuation and accents get in the way of links, caches and some older servers. A slug keeps the words and replaces the rest with a single hyphen: cafe-au-lait-grosse or, with German expansion, a form that keeps ä as ae.
Chinese, Japanese and Korean can stay in the slug. Modern sites do that, and the characters are meaningful. Turn on “Drop non-ASCII characters” only when the target system rejects them. This page does not invent pinyin; a wrong romanization is worse than keeping 北京.
Apostrophes are deleted, not turned into a hyphen, so “don’t” becomes dont rather than don-t. Other punctuation, emoji and symbols become the separator. Repeated separators collapse. The result is trimmed so it does not start or end with a hyphen.
If you still need the original title’s length, measure it with the word counter before you shorten the slug.
The Latin option only strips the accent, so ö becomes o and ß becomes ss, which is grosse. Choose the German option for groesse.
Yes. “Cafe” and “Café” both become cafe. The page that saves the slug has to add a number or an id when the path is already taken. This tool only formats the text.
