Slug Generator

What is a slug?

A slug is the URL-friendly version of a string — typically a page or post title. It uses lowercase letters, numbers, and separators (usually hyphens) instead of spaces and special characters. For example, My Awesome Blog Post! becomes my-awesome-blog-post.

Why slugs matter for SEO

• Readable URLs help users and search engines understand the page.
• Keywords in the slug can reinforce relevance.
• Clean URLs are easier to share and look more trustworthy.

How this tool works

It lowercases your text, removes accents and special characters, and replaces spaces with your chosen separator (hyphen or underscore). Leading and trailing separators are trimmed automatically.

Hyphen vs underscore

For URLs, hyphens (-) are generally recommended — search engines treat them as word separators. Underscores are sometimes preferred for file names or identifiers.

Frequently asked questions

What makes a good URL slug?

A good slug is lowercase, uses hyphens between words, drops special characters and unnecessary stop words, and keeps the relevant keywords so readers and search engines understand the page.

Should I use hyphens or underscores?

For URLs, hyphens are recommended — search engines treat them as word separators, while underscores are better suited to file names and identifiers.

Is it free and private?

Yes — it's free and the slug is generated entirely in your browser, so nothing is sent to a server.
