Why use Slug Generator?

A slug is the URL-friendly version of a title or phrase: lowercase, with spaces and punctuation replaced by a separator. This tool normalizes accented characters with Unicode NFKD decomposition before converting, so letters like an accented e or a tilded n are reduced to their plain form instead of being dropped or mangled. Anything that is not a letter or number is then replaced with your chosen separator, and repeated separators are collapsed into one so you never end up with a double-separator artifact in the result. By default the result is fully lowercase. Turn off the Lowercase option and the tool keeps the same cleaned-up slug but capitalizes the first letter after each separator, producing a title-cased slug instead of an all-lowercase one. Everything runs in your browser as you type, with no button to press and nothing sent anywhere, so the slug updates live and unpublished titles stay private.

Frequently asked questions

Does this handle accented characters?

Yes, accented characters (like an e with an accent or an n with a tilde) are normalized to their closest plain-letter equivalent before slugifying.

What happens to special characters and punctuation?

Anything that is not a letter or number is replaced with the separator, and repeated separators are collapsed into one.

Is my text uploaded anywhere?

No. Accent normalization and separator collapsing are done by JavaScript in your browser, so unpublished page titles you paste here stay private.

Can I use underscores instead of hyphens?

Yes. Choose Underscore from the separator dropdown and every space or special character in your text is replaced with an underscore instead of a hyphen.

What does turning off Lowercase actually change?

The slug is still cleaned up and separator-joined the same way, but the first letter after each separator is capitalized, so a lowercase phrase becomes a title-cased slug instead of an all-lowercase one.
