Should I use hyphens or underscores in a slug?

Hyphens are the safer choice. Google treats hyphens as word separators but not underscores, so 'how-to-brew' ranks better than 'how_to_brew'. The tool offers both in case your CMS requires underscores.

How does it handle accents and special characters?

Accented characters are converted to their plain equivalents (café becomes cafe), and all other special characters are stripped or converted to the separator, so your slug stays URL-safe.

Is my title uploaded anywhere?

No. Slug generation happens entirely in your browser. Your title never leaves your device.

About this tool

A clean URL slug makes your links readable, shareable, and better for search engines. Instead of hand-editing titles into URL-safe form, JoliTools' Slug Generator does it live: type your heading and get a polished slug the moment you finish typing.

The tool lowercases everything, converts spaces and punctuation to your chosen separator, strips accents (café becomes cafe), collapses duplicate separators, and trims any stray separators from the ends. A max-length setting lets you cap the slug at a fixed number of characters, useful when your CMS or SEO plugin enforces URL length limits.

How to use the slug generator

1Type your page title or heading into the input field.
2Choose your separator: hyphen (-) or underscore (_).
3Set a maximum slug length (or 0 for unlimited).
4Watch the clean URL slug generate live as you type.
5Click Copy slug to copy it for use in your URL.

Good to know

Slugs generated here follow real SEO best practice: lowercase letters, hyphens as the default word separator (Google treats hyphens, not underscores, as word boundaries), and no special characters that could break a URL. Everything runs locally in your browser, so your titles are never uploaded or stored.

Frequently asked questions

A slug is the readable part of a URL that identifies a page, like 'how-to-brew-espresso' in example.com/how-to-brew-espresso. Good slugs are short, lowercase, and use hyphens between words.
