Slug Generator — Free 2026

Understanding URL Slugs and Why They Matter

A URL slug is the human-readable portion of a web address that identifies a specific page on your website. For example, in the URL example.com/blog/my-blog-post, the slug is my-blog-post. Good slugs are short, descriptive, and free of special characters — making them easier to read, share, and index by search engines.

When you write a blog post or create a new web page, the CMS often auto-generates a slug from your title. However, these automatic slugs can include stop words, accented characters, or punctuation that clutters the URL. This slug generator gives you full control by converting any text into a clean, URL-safe string in real time.

SEO Benefits of Clean URL Slugs

Search engines like Google use URLs as a ranking signal. A concise slug that contains your target keyword helps crawlers understand what the page is about. Clean slugs also improve click-through rates because users can see at a glance whether a link is relevant to their search. According to best practices, slugs should be lowercase, use hyphens as word separators, and avoid unnecessary words like "the", "and", or "a".

If you are optimizing your content for search, pair this tool with our character counter to ensure your titles and meta descriptions stay within recommended lengths. You can also use the word counter to track your content length for SEO targets.

Hyphens vs. Underscores

Google officially recommends hyphens over underscores in URLs. The reason is straightforward: Google treats hyphens as word separators, so my-blog-post is read as three separate words. Underscores, on the other hand, join words together, meaning my_blog_post could be interpreted as a single token. While underscores are perfectly fine for file names and programming identifiers, hyphens are the safer choice for web URLs.

How This Slug Generator Works

The tool applies a series of transformations to your input text. First, it converts everything to lowercase. Next, it replaces common accented characters with their plain ASCII equivalents — for instance, turning accented vowels into standard letters. Then it strips out any remaining non-alphanumeric characters and replaces spaces (or groups of special characters) with your chosen separator. Finally, it collapses consecutive separators and trims any leading or trailing separators. The result is a clean, URL-ready slug you can paste directly into your CMS, file name, or routing configuration.

This entire process runs locally in your browser. No data is sent to any server, making it safe to use with confidential or unpublished titles. The tool works offline too, so you can generate slugs anywhere without an internet connection.
