Slug generator

How it works

The text is lowercased first, then Unicode-normalised so accented letters lose their marks: Café becomes cafe and Zürich becomes Zurich, while ß is expanded to ss. Every run of characters that is not a letter or a digit collapses into one separator. Separators are trimmed from both ends, so a title that starts with punctuation still yields a clean slug. The input is capped at 500 characters and anything longer is refused with a clear message rather than silently cut. The result appears as plain text with a copy button, and the conversion runs entirely in this page.

Worked example

Take the heading "Café Zürich 2026!" with the hyphen separator. Lowercasing gives café zürich 2026!, dropping the accent marks gives cafe zurich 2026, and replacing the space and the exclamation mark with the separator gives cafe-zurich-2026. Switching the separator to an underscore produces cafe_zurich_2026 from the same text. A title made only of symbols such as "###" has nothing to keep, so the tool says so instead of showing an empty or broken slug.
