Slug Generator

What is a URL slug?

A slug is the human-readable identifier at the end of a URL — the my-first-post in example.com/blog/my-first-post. A good slug contains only lowercase ASCII letters, digits and a separator, so it never needs percent-encoding and reads cleanly in a browser bar, a log file, or a shared link.

This generator does the full normalization pipeline as you type: lowercases the text, strips accents by Unicode-decomposing characters and dropping the diacritic marks (é becomes e, ü becomes u), removes everything that isn't a letter, digit, space or hyphen, then collapses whitespace runs into your chosen separator and trims leading or trailing separators. It all happens in your browser — the text you paste is never uploaded anywhere.

When to use it

Use it whenever a title needs to become an identifier: blog post permalinks in a CMS that doesn't auto-slug (or auto-slugs badly), documentation page paths, file and folder names for exported reports, HTML anchor ids, or slugs for database records and S3 keys.

The separator choice matters. Hyphens are the right default for URLs — search engines treat a hyphen as a word boundary, while underscores glue words together — so use "-" for anything public-facing. Underscores suit code-adjacent identifiers and filenames in snake_case ecosystems, and dots occasionally fit versioned or namespaced artifacts. Whatever you pick, the character count shown under the result helps you keep slugs short; concise slugs are easier to share and less likely to be truncated in previews.

Example

Paste the headline "10 Tips & Tricks: Améliorer votre Café !" and the tool produces 10-tips-tricks-ameliorer-votre-cafe. The ampersand and colon vanish, the accented French characters flatten to plain ASCII, and the stray spaces collapse into single hyphens. Switch the separator to "_" and it becomes 10_tips_tricks_ameliorer_votre_cafe without re-pasting. The "Copy link to this result" button gives you a URL that reopens the tool with the same text and separator loaded — handy when agreeing on a slug convention with a teammate.
