About the Slug Generator

A URL slug is the human-readable part of a web address that represents a page's title or content. This tool converts your text into a safe, URL-ready slug by lowercasing, removing symbols, turning spaces into hyphens, and collapsing repeated separators. Japanese hiragana and katakana are transliterated to romaji using a built-in Hepburn-style mapping. Everything runs in your browser, so your input is never sent to a server.

FAQ

Is the slug generator free to use?
Yes, it is completely free. No registration or installation is required — just open the page and start using it.
Is my input sent to a server?
No. Slug generation runs entirely in your browser using JavaScript, and your input is never sent to or stored on any server.
Are kanji automatically converted to romaji?
This tool converts hiragana and katakana with a built-in romaji mapping. Kanji require a reading dictionary, which cannot run in the browser, so kanji are removed from the slug. If your text contains kanji, replace them with their kana reading first for an accurate romaji slug.
Should I use a hyphen or an underscore as the separator?
For SEO, hyphens ( - ) are generally recommended because Google treats them as word separators. Underscores ( _ ) are more common in code identifiers. Choose based on your use case.
Can I convert multiple titles at once?
Yes. Enter one title per line and a slug is generated for each line, which you can copy all at once — handy for creating many article URLs.
Can I limit the maximum length of generated slugs?
Set a "Max length" value to truncate slugs to that length. Use 0 for no limit. This is useful when you want short, readable URLs.
