What this tool does
Convert text into a URL-friendly slug: lowercase, no diacritics, only letters / digits / a single separator. Useful for blog post URLs, file names, anchor IDs — anywhere a slug from a human title is needed.
How to use it
Paste text, choose a separator (- / _ / .) and optionally keep Unicode letters or cap the length. Result updates live.
Input: Café — Naïve façade!
Output: cafe-naive-facadeLimits and edge cases
- Diacritics are stripped via Unicode NFKD normalization, then combining marks dropped.
café→cafe. - Non-ASCII letters (CJK, Cyrillic, etc.) are collapsed to separators by default. Toggle Keep Unicode to preserve them.
- Runs of non-alphanumeric chars collapse to a single separator, and leading/trailing separators are trimmed.
Frequently asked questions
- Is the slug guaranteed unique?
- No — slugify is deterministic on input but won't dedupe against existing slugs. Add a suffix or check your data store for collisions.
- When should I keep Unicode?
- When the slug is the meaningful identifier in a non-ASCII language (a Japanese blog with Japanese URLs, for example) and your routing layer handles UTF-8 paths.
- Will it lowercase my acronyms?
- Yes — slug convention is lowercase. Toggle 'Lowercase' off to preserve case.
