URL slug generátor

This URL slug generator turns a title into the clean, readable part of a web address. It transliterates accented letters to ASCII, lowercases the text, and replaces spaces and punctuation with a single separator, so "My First Post!" becomes my-first-post.

Everything runs in your browser, so your titles are never uploaded.

A slug is the human-readable identifier in a URL, the my-first-post in example.com/blog/my-first-post. Good slugs are short, lowercase and made of letters, numbers and hyphens, which is both tidier for people and clearer for search engines.

It handles German umlauts the way German sites expect: with German mode on, ä, ö and ü become ae, oe and ue and ß becomes ss. With it off, accents are simply stripped, so ä becomes a, which suits other languages.

You can choose the separator and whether to lowercase. Hyphens are the recommended default because search engines read a hyphen as a word separator but an underscore as a word joiner, so hyphenated slugs rank and read better.

Each line of input is processed separately, so you can paste a whole list of titles and get a clean slug for every one in a single step, handy when setting up many pages or importing content.
