Free SEO URL Slug Generator

Our SEO URL Slug Generator & Text Sanitizer takes any raw text — blog post titles, product names, file names, or headlines — and instantly converts it into a clean, search-engine-optimized URL slug. The entire transformation pipeline runs locally inside your browser using lightweight native JavaScript and Unicode-aware Regular Expressions. No data ever leaves your device.

The tool applies a multi-step sanitization process: first, it strips emojis and non-text symbols using Unicode property escapes. Then it uses NFD Unicode normalization to decompose accented characters (like é, ü, ç, ñ) into their base ASCII equivalents, followed by removing the diacritical marks. Next, it filters out all remaining special characters and punctuation, leaving only letters, numbers, and whitespace. Finally, it joins the remaining words with your chosen separator, collapses any duplicate separators, trims leading and trailing separators, and applies your selected case transformation.

The optional stop-word removal feature filters out common generic words (a, an, the, and, or, but, in, on, at, to, for, with, of, and more) that add length to URLs without providing meaningful SEO value. Shorter, keyword-dense URLs tend to rank better in search results and are easier for users to read and share.

You can choose between hyphens (-) and underscores (_) as separators. Google officially recommends hyphens for word separation in URLs, but underscores are supported for legacy systems and specific naming conventions. Toggle between lowercase (the SEO standard) and uppercase for specialized use cases.
