About This Tool
Clean URLs are a ranking signal. Search engines and users both prefer readable, keyword-rich URLs over random strings of numbers and symbols. Converting a blog title like "How to Build a Website in 2025!" into "how-to-build-a-website-in-2025" takes manual effort — stripping special characters, replacing spaces, removing accents, and lowercasing everything. This free slug generator handles it all instantly. Paste any title, heading, filename, or text and get a clean, URL-safe slug in the format you need. Choose from six styles including kebab-case for URLs, snake_case for databases, camelCase for JavaScript variables, and PascalCase for class names. Set a maximum length to keep URLs concise, or use bulk mode to convert entire lists at once. No signup, no limits — your text stays completely private.
What Is a URL Slug?
A URL slug is the human-readable portion of a web address that identifies a specific page. In the URL example.com/blog/how-to-bake-bread, the slug is "how-to-bake-bread".
Good slugs are:
- Lowercase: URLs are case-sensitive on most servers. Lowercase avoids duplicate content issues.
- Hyphenated: Google treats hyphens as word separators. "bake-bread" registers as two words; "bake_bread" registers as one.
- Concise: Under 60 characters is ideal. Shorter URLs are easier to share and look cleaner in search results.
- Keyword-rich: Include your target keyword in the slug. "chocolate-cake-recipe" ranks better than "post-12345".
- ASCII-safe: No accented characters, emojis, or special symbols that might break in emails or older browsers.
Available Slug Formats
- kebab-case: Words separated by hyphens. The standard for URLs, file names, and CSS classes. "my-blog-post"
- snake_case: Words separated by underscores. Common in Python variables, database columns, and API parameters. "my_blog_post"
- camelCase: First word lowercase, subsequent words capitalized, no separator. Standard for JavaScript and TypeScript variables. "myBlogPost"
- PascalCase: Every word capitalized, no separator. Used for class names in Java, C#, and React components. "MyBlogPost"
- dot.case: Words separated by dots. Used in Java package names and configuration keys. "my.blog.post"
- path/case: Words separated by forward slashes. Useful for generating route paths and directory structures. "my/blog/post"
Bulk Slug Generation
Need to convert multiple titles at once? Enter each title on a separate line and the tool converts them all simultaneously. This is useful for:
- Blog migration: Converting hundreds of post titles to URL-safe slugs when moving platforms
- CMS setup: Generating slugs for product catalogs, category pages, or article archives
- Database work: Creating clean identifiers for table records from display names
- API development: Converting endpoint descriptions to route paths
Results appear line-by-line matching your input order. Copy all results at once or download as a text file for easy import into spreadsheets or scripts.
How Accents and Special Characters Are Handled
The converter uses Unicode normalization (NFD decomposition) to handle international characters:
- Accented letters: "café résumé" becomes "cafe-resume" — diacritics are stripped while preserving the base letter
- Special characters: Ampersands, quotes, brackets, and symbols are removed to keep slugs URL-safe
- Existing separators: Hyphens, underscores, dots, and slashes in the input are treated as word boundaries and re-joined with your chosen style
- CamelCase splitting: "myVariableName" is detected and split into "my-variable-name" when converting to kebab-case
- Numbers preserved: "Top 10 Tips for 2025" becomes "top-10-tips-for-2025" — numbers are always kept
SEO Best Practices for URL Slugs
URL structure directly impacts search rankings and click-through rates. Follow these guidelines:
- Include your primary keyword: Place the target keyword near the beginning of the slug. "chocolate-cake-recipe" beats "recipe-for-delicious-homemade-chocolate-cake".
- Remove stop words: Articles like "a", "the", "and", "or" add length without SEO value. "build-website" is better than "how-to-build-a-website".
- Keep it under 60 characters: Use the max length setting to enforce limits. Google truncates long URLs in search results.
- Use hyphens, not underscores: Google confirmed that hyphens are treated as word separators while underscores are not. Always use kebab-case for public URLs.
- Avoid changing slugs after publishing: Changing a URL breaks existing backlinks and social shares. Set slugs correctly the first time.
- Match user intent: Slugs should describe what the page delivers. Users see the URL before clicking in search results.
When to Use Each Slug Style
Different contexts require different naming conventions:
- Web URLs and permalinks: Always kebab-case. It is the universal standard for URLs and the only style Google recommends.
- Python code: snake_case for variables and functions per PEP 8 style guide.
- JavaScript/TypeScript: camelCase for variables and functions, PascalCase for classes and React components.
- Database columns: snake_case is most common across PostgreSQL, MySQL, and SQLite conventions.
- CSS classes: kebab-case (also called "spinal-case") following BEM methodology.
- Java packages: dot.case for package names like "com.example.myapp".
- File paths: path/case for generating directory structures and routing hierarchies.
