URL Slug Generator

Convert titles, headlines or any string into clean URL slugs ready to use in your routes. Strips diacritics, normalises whitespace, replaces unsafe characters with a separator, and lowercases by default. Strict mode keeps only ASCII letters and digits, ideal for traditional URL paths. Pre-clean inputs with Remove Letter Accents, normalise capitalisation in the Letter Case Converter, or escape the final slug through the URL Encoder when it needs to ride a query string.

How it works

We normalise to NFD (separating letters from accents), drop combining marks, optionally lowercase, then replace anything that is not a Unicode letter or number with the separator. Strict mode tightens this to ASCII alphanumerics. Trims leading and trailing separators.

How to use it

  1. Paste the source text

    Drop in a title, a heading, a product name, or a list of phrases. The generator handles single lines and bulk batches alike.

  2. Pick a separator

    Hyphen is the SEO default and the safest bet for URLs. Underscore is fine for filenames; the generator keeps your choice consistent.

  3. Pick Unicode or ASCII

    Unicode keeps non-Latin scripts intact for international URLs. ASCII strict mode strips accents and transliterates for legacy systems.

  4. Copy the slug

    Take the result into your CMS, your router, or your file pipeline. Every slug is lowercase and free of consecutive separators.
