About Slug Generator

Slug Generator turns any title or sentence into a clean, URL-safe slug — the part of a URL that comes after your domain and identifies the page (for example, "/blog/how-to-write-good-slugs"). Type your text, choose a separator (hyphen, underscore, or dot), and copy the result. Slugs need to be ASCII-friendly, lowercase, and free of punctuation so they work everywhere — in URLs, file paths, database keys, and filenames. The tool handles the trickier cases automatically: strips diacritics from accented characters (so "café" becomes "cafe"), collapses whitespace and existing punctuation into your chosen separator, removes leading and trailing separators, and optionally truncates the result to a max length without leaving a trailing dash. Common uses include generating SEO-friendly URLs from blog post titles, creating safe file names from user-uploaded names, building page paths in static site generators, naming Kubernetes resources, and producing predictable identifiers from human-readable strings. Hyphens are the standard for SEO — Google treats them as word separators in URLs, while underscores are not. Underscores are common in filenames and database identifiers. Dots are useful for nested namespaces.

How Slug Generator works

  1. Type or paste any title, sentence, or string into the input.
  2. The tool runs Unicode NFKD normalization to decompose accented letters into base + combining marks.
  3. It then strips diacritics, collapses whitespace and existing punctuation, and lowercases the result.
  4. Pick a separator: hyphen (SEO standard), underscore (filenames/DB), or dot (namespaces).
  5. Optionally enforce ASCII-only and a max length without leaving a trailing separator.

When to use Slug Generator

  • Generate an SEO-friendly URL slug from a blog post title (e.g. 'How to Write Good Slugs' → 'how-to-write-good-slugs').
  • Create a safe filename from a user-uploaded file's original name.
  • Build a page path in a static site generator (Next.js, Astro, Hugo).
  • Name a Kubernetes resource that has to be DNS-1123 compliant (lowercase letters, digits, hyphens).
  • Generate a stable cache key from a human-readable description.
  • Turn a feature name into a CSS class or HTML id that's safe to use without escaping.

  • ASCII-only toggle for systems that can't handle non-Latin slugs.
  • Max-length truncation that doesn't leave a trailing separator.
  • Free, instant, local-only — no signup or per-day limits like some online slug tools.
