- A URL slug is the part of a URL that identifies a page in human-readable form — e.g.
/blog/how-to-build-a-rest-api. - Unicode characters like accented letters (é, ñ, ü) are transliterated to their ASCII equivalents for maximum compatibility.
- Stop words (a, the, in, of, etc.) can be removed to create shorter, cleaner URLs that rank better for SEO.
- Everything runs in your browser — no data is sent over the network.
Tips & Best Practices
Keep slugs under 75 characters for SEO
Google displays about 75 characters of URL in search results before truncating. Shorter slugs are easier to share, copy, and remember. Remove stop words (the, a, an, in, of, for) and use 3-5 keywords maximum: /tools/json-formatter not /tools/the-best-json-formatter-and-validator-tool-for-developers.
Changing slugs breaks existing links — always redirect
Every external link, bookmark, and search engine index points to your current URL. Changing a slug without a 301 redirect creates 404 errors and loses accumulated SEO authority. In Next.js, add redirects in next.config.ts. Always maintain a redirect map for renamed pages.
Handle Unicode slugs with transliteration, not removal
"Über die Brücke" should become uber-die-brucke, not -die-br-cke. Use a transliteration library (speakingurl, limax, slugify) that converts ü→u, ñ→n, é→e, ø→o. For CJK content, consider Pinyin romanization or keeping Unicode in the URL (modern browsers display it properly).
Validate slugs to prevent path traversal
User-generated slugs like ../../../etc/passwd or ..\windows\system32 can enable directory traversal if used directly in file paths. Always sanitize: remove dots, slashes, and backslashes. Validate against a strict regex like /^[a-z0-9]+(?:-[a-z0-9]+)*$/ and never use slugs to construct file system paths without validation.
