Text to URL Slug

About the Text to URL Slug

The Text to Slug Converter turns any title or phrase into a URL-safe slug — the lowercase, hyphen-separated string that appears after the domain in a clean URL. A title like “10 Tips for Better Sleep!” becomes 10-tips-for-better-sleep, ready to drop into a WordPress permalink, a Next.js dynamic route, or a Jekyll post filename.

Slugs matter for SEO and usability. Search engines read URLs as ranking signals, so a slug that contains the target keywords (like how-to-bake-sourdough-bread) reinforces the page topic. Human readers scan URLs in search results and share links in chat, so a readable slug builds trust. Long, query-string-heavy URLs (like ?p=12345) lose click-through rate compared to descriptive slugs — multiple SEO studies have confirmed this.

The tool gives you three knobs: lowercase (on by default in most CMSes), stopword stripping (which trims “the,” “a,” “an,” “is,” etc. to make the slug shorter and more keyword-dense), and ASCII transliteration (which converts “café” to “cafe” and “München” to “Munchen” for maximum compatibility).

How It Works

The conversion happens in three stages. First, if ASCII transliteration is enabled, the string is Unicode-normalized to NFD (decomposed form), which separates base characters from their diacritical marks. The combining marks (Unicode block U+0300-U+036F) are then stripped, leaving the base ASCII letter behind. So “é” becomes “e” and “ñ” becomes “n.” Characters that cannot be transliterated (CJK, Cyrillic, Arabic) are removed entirely.

Second, the string is split on whitespace, hyphens, and underscores into an array of words. Stopword stripping filters out a built-in list of common English function words: articles, conjunctions, and short prepositions. The list is intentionally small (~20 words) to avoid over-aggressive trimming — we keep verbs and nouns that carry meaning.

Third, words are lowercased (if enabled) and joined with the chosen separator (hyphen or underscore). Consecutive separators are collapsed to a single one, and leading/trailing separators are stripped. The result is a clean, URL-safe slug that contains only letters, digits, and the separator character.

Worked Examples

The default “The Quick Brown Fox Jumps Over the Lazy Dog!” with hyphen separator and lowercase on produces the-quick-brown-fox-jumps-over-the-lazy-dog — 42 characters, 9 words. Toggle “Strip common stopwords” and the output becomes quick-brown-fox-jumps-over-lazy-dog — 33 characters, 7 words, removing “the” (twice) and “the.” This is the WordPress default behavior.

For a non-English title like “Café à Paris: Mon Guide” with ASCII transliteration enabled, the output is cafe-a-paris-mon-guide. Without transliteration, the accented characters are preserved as café-à-paris-mon-guide, which works in modern browsers but may break in older crawlers or analytics tools that do not handle UTF-8 properly.

For a longer, more SEO-focused example, try “How to Bake Sourdough Bread at Home: A Step-by-Step Guide.” With stopword stripping, you get how-bake-sourdough-bread-home-step-step-guide — removing “to,” “at,” and “a” but keeping “how” because it carries search intent. The slug is concise, keyword-rich, and human-readable.

When to Use This Tool

• Generating permalinks for WordPress, Ghost, Hugo, Jekyll, or Next.js blog posts.
• Creating URL-safe anchor names for section headings in long-form documentation.
• Producing file naming conventions for assets (e.g., image filenames matching their content).
• Cleaning up product names into URL-friendly handles for e-commerce platforms.
• Normalizing YouTube video titles into shorter shareable URL fragments.
• Generating CSS class names from component descriptions in kebab-case.
• Building i18n-safe slugs for multilingual sites that need ASCII-only URLs.

Limitations & Disclaimer

This tool generates slugs using simple text normalization and does not guarantee uniqueness — you must verify the slug does not conflict with an existing URL on your site. ASCII transliteration handles only Latin-script accents (é, ü, ñ) and removes non-Latin scripts entirely; for CJK, Cyrillic, or Arabic content you need a dedicated transliteration library. The stopword list is small and English-only — multilingual content requires a language-aware stopword list. The tool does not check slug length against platform limits or SEO best practices automatically. See our disclaimer for full terms.
