Quick answer

A text-to-slug converter transforms text into URL-safe identifiers by lowercasing it, replacing spaces with hyphens, stripping punctuation and diacritical marks, and collapsing multiple hyphens into one. This creates clean, readable web addresses and SEO-friendly links automatically.

Formula & method

Paste or type your text into the input field. The converter automatically processes it by: (1) removing all accents and diacritical marks, (2) converting to lowercase, (3) removing punctuation and special characters, (4) replacing spaces with hyphens, and (5) collapsing any consecutive hyphens into a single hyphen. Your slug appears instantly with no page refresh needed.

Example 1: Blog Post Title

hello-world-2024
Why
Punctuation (comma, exclamation mark) is removed, text is lowercased, and spaces become hyphens.
Example 2: International Characters

Café au Lait
Result
cafe-au-lait
Why
Accents are stripped (é becomes e), text is lowercased, and spaces are replaced with hyphens.
Example 3: Multiple Spaces and Hyphens
Input
New York City---USA
Result
new-york-city-usa
Why
Multiple consecutive hyphens are collapsed into a single hyphen, and spaces are converted to hyphens.

When to use this tool

  • Creating SEO-friendly URL paths for blog posts, product pages, or content management systems
  • Generating readable identifiers for database slugs, file names, or URI segments from user-provided titles
  • Automating URL slug generation to maintain consistent formatting across your website or application

Common mistakes

  • Expecting underscores instead of hyphens: Slugs use hyphens (not underscores) as word separators because they're more SEO-friendly and recognized as word boundaries by search engines.
  • Thinking special characters are preserved: All punctuation, symbols, and non-alphanumeric characters are completely removed—they don't just get replaced.
  • Forgetting that leading/trailing spaces matter: Extra whitespace at the beginning or end of text is stripped before conversion, so 'Hello World ' and 'Hello World' produce identical slugs.

Frequently asked questions

Why do slugs use hyphens instead of underscores?

Search engines treat hyphens as word separators, improving readability and SEO. Underscores are treated as connectors, making words appear concatenated. For example, 'hello-world' ranks better for both 'hello' and 'world' individually.

Can I customize the slug after conversion?

Yes. Most slug converters generate a baseline output, which you can manually edit to adjust length, remove words, or make other refinements before using it in your URL or database.

Does this tool preserve numbers?

Yes. Numbers are kept in the slug. For example, 'iPhone 15 Pro' becomes 'iphone-15-pro'.

What happens to apostrophes or quotes?

All punctuation, including apostrophes and quotation marks, is removed. 'Don't' becomes 'dont', and 'John's Book' becomes 'johns-book'.

Is my text uploaded anywhere?

No. This tool runs 100% in your browser. Your text is never sent to any server or stored anywhere.

Can it handle multiple languages?

Yes. The tool removes accents and diacritics from any language (é, ñ, ü, etc.), making it safe for international text. However, non-Latin scripts (Arabic, Chinese, Cyrillic, etc.) may require special handling depending on implementation.
