About this calculator
Convert any text into a URL-friendly slug with hyphen or underscore separators. The result updates as you type and has a copy button.
Use it to create page URLs, file names, CSS class names or database keys from plain titles.
How to use it
- Type the Input Text.
- Pick Hyphen or Underscore.
- Copy the slug from the output box.
Rules
A slug is the readable part of a URL. The tool lower-cases the text, replaces accented letters with plain ones (é becomes e), removes symbols, turns spaces into the chosen separator and collapses repeats. Hyphens are the standard word separator for search engines, while underscores join words into one in some systems.
Worked example
Hello World! Café 2026
| Slug with hyphens | hello-world-cafe-2026 |
| Slug with underscores | hello_world_cafe_2026 |
Tips and common mistakes
- Keep slugs short: three to five meaningful words.
- Use hyphens, not underscores, for SEO.
- Drop filler words such as a, the and of if the meaning stays clear.
- Never change a live URL without a 301 redirect.
- Avoid dates in slugs for evergreen articles.
