How It Works
Type or paste text into the input field and a URL-safe slug appears instantly. The tool strips special characters, replaces spaces with your chosen separator, and optionally lowercases and transliterates accented characters. For bulk mode, put each title on its own line and get a matching list of slugs.
Everything runs client-side in JavaScript. No data leaves your browser, so it is safe for unreleased titles and internal project names.
What Is a URL Slug?
A slug is the part of a URL that comes after the domain and identifies a specific page in a human-readable way. For example, in example.com/blog/what-is-a-url-slug the slug is what-is-a-url-slug.
Good slugs are short, descriptive, and contain only lowercase letters, numbers, and hyphens. They help search engines understand the page topic and make URLs easier for people to share and remember.
SEO-Friendly URL Best Practices
| Do | Don't | Why |
|---|---|---|
/blog/url-slug-best-practices | /blog/post?id=48372 | Descriptive slugs tell users and crawlers what the page is about |
| Keep slugs under 60 characters | Stuff every keyword into the URL | Short URLs rank better and display cleanly in SERPs |
| Use hyphens as word separators | Use underscores or spaces | Google treats hyphens as word separators; underscores do not split words |
| Use only lowercase letters | Mix upper and lowercase | URLs are case-sensitive on most servers; mixed case causes duplicate content |
| Remove stop words (a, the, and) | Include every word from the title | Shorter slugs are more memorable and easier to share |
| Transliterate accented characters | Use raw Unicode in URLs | ASCII slugs are universally compatible and avoid encoding issues |
FAQ
Should I include dates in my URL slugs?
Generally no. Dates make URLs longer and signal that content may become stale. If you update an article, the old date in the URL works against you. Use dateless slugs unless your content is inherently time-specific (e.g., "2025-nfl-draft-results").
How long should a slug be?
Aim for 3-5 words, or roughly 50-60 characters. Google truncates long URLs in search results and studies show shorter URLs correlate with higher rankings. Use the Max Length option to enforce a limit.
Does changing a slug hurt SEO?
Yes, if you don't set up a 301 redirect from the old URL to the new one. Without a redirect, you lose all link equity and existing backlinks return 404. Always redirect when you change a live slug.
What does transliteration do?
Transliteration replaces accented and non-ASCII characters with their closest ASCII equivalents. For example, "Café München" becomes "cafe-munchen" instead of producing percent-encoded characters like %C3%A9 in the URL.
