About this tool

Convert any text into a URL-friendly slug. Choose separator (hyphen or underscore), toggle lowercase/uppercase, set max length, and see a live preview as you type. Perfect for blog post URLs, product links, and permalink generation.

What a slug is

A slug is the human-readable part of a URL that identifies a page. /blog/how-to-bake-bread is more memorable, more search-friendly, and more shareable than /blog/post/4823. Search engines also use words in the URL as a minor ranking signal. Good slugs are short, lowercase, hyphen-separated, ASCII, and free of stop words.

How the generator builds your slug

  • Lowercases (or uppercases) the input as a single step.
  • Strips accents — café becomes cafe.
  • Removes punctuation and special characters.
  • Replaces whitespace with the chosen separator (hyphen or underscore).
  • Collapses consecutive separators into one.
  • Trims to a maximum length if set, breaking at a word boundary when possible.

Best practices

Prefer hyphens to underscores. Google treats hyphens as word separators and underscores as joiners, so my-best-recipe is two queryable words but my_best_recipe is one. Keep slugs under 60 characters when possible. Drop filler words like "the" and "and" if the meaning survives. Once a page is published, do not change its slug without setting up a 301 redirect — old links and shares will break otherwise.

Frequently asked questions

What characters are removed?

All non-alphanumeric characters except the chosen separator are stripped. Accented characters (é, ñ, ü) are converted to their ASCII equivalents (e, n, u).

Is my text sent to a server?

No. Everything runs locally in your browser.

Can I use underscores instead of hyphens?

Yes. Toggle the separator between hyphen (-) and underscore (_). Hyphens are generally preferred for URL slugs because Google treats them as word separators.

How do I create an SEO-friendly URL slug?

Keep it short (under 60 characters), use lowercase, use hyphens as separators, drop filler words, and include your primary keyword. The generator handles formatting automatically.

What is a URL slug?

A URL slug is the human-readable identifier in a URL path, like "best-coffee-shops-nyc" in /blog/best-coffee-shops-nyc. Good slugs are short, descriptive, and improve both SEO and shareability.

Should slugs include stop words?

Generally no. Drop words like "the", "a", "and", and "of" unless removing them changes meaning. Shorter, keyword-focused slugs perform better.
