Convert any text into a clean, URL-friendly slug — perfect for blog posts, products, and SEO-friendly URLs.
The Slug Generator turns any headline, title, or phrase into a clean, URL-friendly slug: lowercase text with words joined by hyphens and all unsafe characters removed. Paste something like "Top 10 IoT Protocols (2026 Edition)!" and it returns top-10-iot-protocols-2026-edition, ready to drop into a permalink, file name, anchor ID, or database key.
It runs entirely in your browser and is used by bloggers, CMS editors, developers, and SEO teams who need consistent, readable URLs. Because slugs feed directly into search-engine indexing and shareable links, a descriptive, keyword-focused slug is usually better for both users and crawlers than an auto-generated numeric ID like ?p=4821.
A slug is the human-readable portion of a URL that identifies a specific page, for example the "how-to-flash-esp32" part of example.com/blog/how-to-flash-esp32. The generator applies a series of transformations: it converts the text to lowercase, normalizes accented characters (turning cafe with an accent into cafe), strips characters outside the safe set of a to z, 0 to 9, and hyphens, collapses runs of spaces or symbols into a single separator, and trims any leading or trailing hyphens.
Slugs stick to unreserved URL characters defined in RFC 3986, so the output never needs percent-encoding and stays readable in browsers, links, and analytics reports. Emoji, ampersands, slashes, and query symbols are removed rather than encoded. The result is a compact, stable identifier that is safe in URLs, Git branch names, S3 object keys, CSS class names, and HTML id attributes.
Yes, it is completely free with no sign-up. All processing happens locally in your browser using JavaScript, so your text is never uploaded to a server or stored anywhere.
It removes anything outside a to z, 0 to 9, and the separator. Spaces and punctuation become a single hyphen, accented letters are simplified to their base form, and symbols like &, /, ?, and emoji are stripped entirely.
Hyphens are the standard for web URLs because Google treats them as word separators, while underscores are read as joiners. Use underscores only where a system requires them, such as certain file names or database identifiers.
There is no hard rule, but shorter is usually better. Aim for roughly three to five meaningful words; long slugs get truncated in search results and are harder to share, so drop stop words like "the" and "of" when you can.
Accented Latin characters are transliterated to their closest ASCII equivalent (for example, e-acute becomes e). Scripts with no ASCII mapping, such as Chinese or Arabic, will be stripped, so provide a romanized or English version if you need a readable slug.
Yes. A page's slug is part of its URL, so editing it changes the address and can break inbound links and bookmarks. If you must change a live slug, set up a 301 redirect from the old URL to the new one.
Slugs are conventionally lowercase because URLs can be case-sensitive on many servers, which means /My-Page and /my-page could resolve to different pages. This tool lowercases everything to avoid that ambiguity.
