Why use hyphens instead of underscores in URLs?

Google treats hyphens as word separators but underscores as word joiners. For SEO, "my-blog-post" is read as three separate words, while "my_blog_post" is read as one word. Hyphens are the recommended standard for URL slugs.

What are stop words and should I remove them?

Stop words are common words like "a", "the", "in", "on", "to" that add little meaning to a URL. Removing them creates shorter, cleaner slugs. However, sometimes stop words add important context — use the toggle to see which version you prefer.

How does transliteration work?

The tool automatically converts accented characters (like é, ü, ñ) to their ASCII equivalents (e, u, n). For example, "san-josé" becomes "san-jose" and "München" becomes "munchen". Special symbols like copyright and euro are also normalized.

What is a good maximum slug length?

Most experts recommend keeping URLs under 75 characters total, so the slug portion should typically be under 50-60 characters. However, the tool defaults to 200 characters to give you flexibility — you can use the max length slider to enforce shorter slugs.

What is URL Slug Generator?

A URL slug is the human-readable part of a web address that comes after the domain (e.g. /my-blog-post). Search engines prefer clean, descriptive slugs over auto-generated IDs or messy strings. This tool helps you create slugs that are SEO-friendly, readable, and consistent.

The slug generator removes special characters, converts accented letters to plain ASCII, optionally removes common stop words, and ensures your slug stays within reasonable length limits. Everything runs client-side — nothing is sent to a server.
