Guide: URL Slug Generator
↑ Back to toolWhat is this tool?
This URL slug generator turns titles, headings, and phrases into URL-friendly slugs: lowercase or mixed case, no accents, and a hyphen (-) or underscore (_) between words. It uses Unicode normalization to strip diacritics (e.g. é → e), replaces non-letter/number runs with your separator, and can collapse repeated separators. Copy the result for blog permalinks, CMS fields, API paths, and filenames. All processing runs in your browser—no sign-up.
A slug is the human-readable segment of a URL path (e.g. /blog/my-great-post). Good SEO slugs are short, readable, and avoid spaces and special characters.
💡 Quick tip
Use hyphens for typical web URLs and kebab-case SEO; use underscores if your stack or filenames prefer snake_case. Turn on Collapse repeats so multiple spaces or dashes become a single separator.
Why use a slug generator?
Developers and content editors use a slug generator or permalink generator to turn headlines into safe paths without hand-editing. This tool handles accents, punctuation, and spacing consistently—faster than regex in your head and safer than guessing.
- Generate SEO-friendly URLs from article titles
- Create stable filenames and branch names from phrases
- Preview string to slug output before saving to a CMS or API
Key features
- Separator — Hyphen (-) or underscore (_).
- Letter case — Lowercase (typical for URLs) or mixed case if you need preserved casing.
- Repeated separators — Collapse multiple consecutive separators to one, or keep runs for special cases.
- Diacritics — Normalized to ASCII-friendly letters (NFD + strip combining marks).
- Copy slug — One-click copy to clipboard.
- Session persistence — Input and options are remembered in session storage for this tab.
How to use
- Enter text — Paste or type a title, phrase, or sentence in the text area.
- Choose options — Pick separator, letter case, and whether to collapse repeated separators.
- Copy — Use Copy slug to copy the result. Optionally open the URL Shortener for a short link workflow.
Use cases
| Scenario | How this tool helps |
|---|---|
| Blog / CMS permalinks | Turn post titles into clean url slug values for WordPress, Ghost, or headless CMS. |
| REST API paths | Generate path segments from resource names (e.g. product titles) safely. |
| Files & exports | Create filesystem-safe names without spaces or special characters. |
| SEO | Prefer readable kebab case url slugs with hyphens for search-friendly URLs. |
Best practices
- Keep slugs short — Remove stop words in the source title when possible, or edit the input before slugifying.
- Stay consistent — Pick one separator and case style across your site.
- Avoid duplicate paths — Your CMS or router should still enforce uniqueness; the slug is only one part.
Common mistakes
- Empty slug — If you only enter punctuation or symbols, the result may be empty. Add meaningful words.
- Mixed case in URLs — Some servers treat paths as case-sensitive; lowercase is usually safest for public URLs.
FAQ
What is a URL slug?
The part of a URL path after the domain, often built from words (e.g. /docs/url-slug). This tool generates that segment from arbitrary text.
Is this slug generator free?
Yes. It runs in your browser with no sign-up. Use Copy slug to export the result.
Hyphen or underscore for SEO?
Hyphens are widely used for readable URLs (kebab-case). Underscores are often used in code or filenames. Search engines can handle both; choose what matches your site and conventions.
How are accents handled?
Text is normalized and combining marks are removed so accents become plain letters (e.g. café → cafe).
