Generate URL slugs live in your browser
Type or paste a title — the finished slug appears instantly below: lowercase, hyphen-separated, free of special characters. The German mode handles umlauts properly (ä→ae, ö→oe, ü→ue, ß→ss), and separator plus lowercasing are toggleable. Everything runs locally in your browser — no upload, no signup.
What makes a good slug?
The slug is the readable part of a URL that identifies the page — my-first-post in example.com/blog/my-first-post. The technical foundation is RFC 3986 (2005): the standard defines exactly 66 "unreserved characters" (A–Z, a–z, 0–9 plus -, ., _, ~) that are allowed in URLs without percent-encoding. Everything else — spaces, umlauts, punctuation — must be encoded (%C3%A4 for ä), which makes URLs ugly and error-prone when shared. A good slug therefore sticks to lowercase letters, digits and hyphens. Keeping it short pays off practically too: the sitemap protocol (sitemaps.org) allows at most 2,048 characters per URL.
Hyphen or underscore?
Hyphen. Google's Search Central documentation on URL structure explicitly recommends separating words with hyphens (-) rather than underscores (_), because hyphens are treated as word boundaries. This tool's underscore option exists for cases where a system demands it — internal file or field naming, for example.
How does the German mode handle umlauts?
Order is everything: the German mode first replaces ä→ae, ö→oe, ü→ue and ß→ss, and only then strips remaining accents via Unicode decomposition (NFD). Decomposing directly would reduce ä to a plain a — "Größe" would become "grose" instead of the correct "groesse". The English mode does the opposite on purpose (ä→a, é→e), matching what international CMS slug functions usually do. Examples:
- "Größenwahn & Co." → DE:
groessenwahn-co· EN:grossenwahn-co - "Café Décor" → both modes:
cafe-decor
Repeated separators collapse into one, and separators at the start or end are stripped.
What are the generator's limits?
An honest limitation: non-Latin scripts (Cyrillic, Chinese, Arabic, Greek …) are not transliterated — they are removed, so a purely Cyrillic title yields an empty slug. Proper support requires language-specific transliteration tables that this deliberately lean tool does not ship. Alternative: modern browsers and servers also accept percent-encoded Unicode URLs (IRIs), as used by Wikipedia, for example.
Is my title sent anywhere?
No. The slug is generated on your device with every keystroke — nothing is uploaded or analyzed. Unpublished article titles, product names and internal project names stay private; the tool even works offline.
