Slugify — Text to URL Slug

What is Slugify — Text to URL Slug?

Slugify is a free online slug generator that turns a title, headline, or any phrase into a clean URL slug — the readable part of a web address, like "my-first-blog-post". Developers, bloggers, and SEO specialists use it to create permalinks, file names, anchor IDs, and CSS class names from human-readable text. It keeps only ASCII letters and digits, replacing every space, punctuation mark, and symbol with your chosen separator. You can pick a hyphen (the kebab-case standard for URLs) or an underscore, force the slug to lowercase, strip diacritics so accented characters such as é, ü, and ñ become e, u, and n, and collapse runs of repeated separators into one. Because the widget renders only with JavaScript, this text is the indexable description: convert text to a URL slug, generate a permalink, and clean up a string for use in a link.

How to use Slugify — Text to URL Slug

2. Open the settings panel and choose a separator: hyphen (-) for standard URLs or underscore (_).
3. Toggle Lowercase to force the slug to lower case, on by default.
4. Toggle Strip accents to convert characters like é or ñ to plain ASCII (e, n).
5. Toggle Collapse repeats to merge runs of separators into a single one.
6. Read the finished slug in the read-only Output box and click Copy to use it.

Frequently asked questions

What is a URL slug?

A slug is the human-readable part of a web address that identifies a page, such as "my-first-blog-post" in example.com/blog/my-first-blog-post. A good slug uses only lowercase letters, digits, and hyphens, which is exactly what this tool produces.

What is the difference between the hyphen and underscore separator?

Hyphen (-) is the convention for URLs and SEO, because search engines treat hyphens as word boundaries — pick it for permalinks. Underscore (_) is common for file names, code identifiers, and CSS, where a hyphen may not be wanted. The tool uses your chosen character to join the words.

What does Strip accents do?

It normalizes the text (Unicode NFKD) and removes combining diacritical marks, so accented Latin characters are reduced to plain ASCII: é becomes e, ñ becomes n, ü becomes u. Characters with no ASCII equivalent, such as most CJK or emoji, are dropped because the slug keeps only A–Z, a–z, and 0–9.

What does Collapse repeats do?

With it on, several separators in a row are merged into one, so "Hello World" becomes "hello-world". With it off, each space, punctuation mark, or symbol becomes its own separator, so the same input becomes "hello---world". Leading and trailing separators are always trimmed either way.

Is my text uploaded to a server?

No. The whole conversion runs 100% client-side in your browser using built-in JavaScript string functions. Nothing you type is uploaded, stored, or sent anywhere, so you can safely slugify private titles, internal page names, or sensitive content.
