Slug Generator

What this tool does

A slug is the URL-friendly version of a title — lowercase, with spaces and punctuation replaced by hyphens, and any character that isn't a letter, number, or separator stripped out entirely. This tool converts any text into a clean slug live as you type: accented letters are converted to their plain ASCII equivalent where possible, runs of whitespace or punctuation collapse into a single separator, and leading or trailing separators are trimmed. Everything happens locally in your browser.

Example use case

Publishing a blog post titled "10 Tips for Better Sleep (2026 Guide)!" needs a URL like /10-tips-for-better-sleep-2026-guide rather than the raw title with spaces and punctuation, which browsers would otherwise percent-encode into an ugly, hard-to-read address. Slugs are also commonly used for file names, CSS class names, or unique keys derived from a display name.

Hyphens vs. underscores

Hyphens are the web convention — search engines treat them as word separators, while underscores are sometimes treated as joining two words into one. Most platforms (WordPress, GitHub, e-commerce URLs) expect hyphens, but some systems such as certain file-naming conventions or legacy databases expect underscores instead, which the toggle above switches between.
