Type a title and get a clean, lowercase, hyphen-separated slug ready to use in a URL.
A slug is the part of a URL that identifies a specific page in readable form — the section after the domain, like the "my-first-blog-post" in example.com/blog/my-first-blog-post. Search engines and readers both benefit from slugs being short, lowercase, and free of spaces or special characters, since spaces get encoded as ugly "%20" sequences and mixed case creates unnecessary inconsistency between links.
This tool converts any title, heading, or arbitrary sentence into that clean format automatically. It lowercases every character, strips punctuation like colons, apostrophes, and exclamation points, and replaces spaces with your choice of hyphens or underscores. Hyphens are the more common convention and the one generally recommended for SEO, since search engines treat hyphens as word separators, while underscores are sometimes preferred for file names or specific coding conventions.
It's used constantly by bloggers and content managers setting the URL slug field when publishing a post, developers generating consistent file names from user-submitted titles, and anyone building a static site where page URLs need to be derived from a page title automatically rather than typed by hand every time. Because it runs locally, you can generate slugs from draft titles you haven't published yet without any of that content leaving your browser.
