Why Slugify Text for URLs and SEO?
Our free slugify tool converts text into URL-friendly slugs by removing accents, stripping special characters, replacing spaces with hyphens or underscores, and normalizing to lowercase—creating clean, SEO-optimized URLs that search engines and browsers handle correctly. URL slugs are the readable portion of web addresses after the domain name (like "best-chocolate-cake-recipe" in example.com/blog/best-chocolate-cake-recipe), and they directly impact search engine rankings, click-through rates, and user experience. WordPress, Shopify, Medium, and all modern CMS platforms require properly formatted slugs, making this tool essential for bloggers, SEO professionals, e-commerce managers, and web developers.
Poor URL slugs with spaces, special characters, or non-ASCII characters break links, create 404 errors, and harm SEO performance. Our tool handles international text by automatically removing diacritics (café becomes cafe, naïve becomes naive), converts Unicode characters to ASCII equivalents, and eliminates punctuation that causes URL encoding issues. Beyond URLs, developers use slugs for database keys, CSS class names, file naming conventions, and API endpoints where special characters would cause parsing errors or security vulnerabilities. The tool processes multiple lines simultaneously, making it perfect for batch-converting blog post titles, product names, or category labels.
Common Use Cases
🔗 SEO-Friendly Blog Post URLs
Search engines rank pages higher when URLs contain relevant keywords separated by hyphens rather than underscores or spaces. Converting blog post titles like "10 Tips for Better Sleep!" into "10-tips-for-better-sleep" improves click-through rates from search results and makes URLs more shareable on social media. Clean slugs without special characters prevent broken links and improve user trust.
After slugifying titles, use Word Counter to optimize content length, then Case Converter for title case consistency.
🛍️ E-Commerce Product URLs
Online stores need URL-safe product slugs for thousands of items with names containing special characters, brand symbols, or international characters. Converting "Women's Running Shoes - Size 8.5" to "womens-running-shoes-size-8-5" creates canonical URLs that work across all platforms, prevent duplicate content issues, and integrate cleanly with payment gateways, shipping APIs, and inventory management systems.
Slugify product names first, then use Remove Duplicates to find conflicts and Sort Lines to organize your URL structure.
💻 Database Keys & Programming Identifiers
Developers need database-safe identifiers without spaces or special characters that could break SQL queries or NoSQL document keys. Converting user-generated category names, tag labels, or custom field names into slugs ensures consistent, predictable identifiers. Slugs work as CSS class names, JavaScript variable names, and file names where special characters would cause syntax errors or filesystem issues.
For code-safe identifiers, combine with Case Converter for camelCase or snake_case, then Find & Replace for batch renaming operations.
📁 File & Folder Naming
Cross-platform file systems (Windows, Mac, Linux) handle special characters differently, causing problems when sharing files or deploying code. Slugifying file names like "Q3 Financial Report (Final).pdf" to "q3-financial-report-final.pdf" ensures compatibility, prevents upload errors to cloud storage, and avoids issues with build tools, version control systems, or automated deployment pipelines that break on special characters.
After creating file-safe names, use Remove Empty Lines to clean lists, then Text Statistics to analyze naming patterns.
How Slugification Works
Our slugify algorithm processes text through multiple transformation steps for maximum compatibility. First, it normalizes Unicode characters by removing diacritical marks using Unicode decomposition—breaking characters like "é" into base letter "e" plus accent mark, then stripping the accent. This handles French, Spanish, German, and other European languages correctly. The tool converts all text to lowercase by default (optional) for URL consistency, as search engines treat "Blog-Post" and "blog-post" as different URLs, potentially causing duplicate content penalties.
Next, the algorithm removes special characters and punctuation including periods, commas, apostrophes, quotes, ampersands, and symbols that either break URLs or get percent-encoded into ugly character sequences like %20 or %26. Spaces are replaced with your chosen separator—hyphens (-) for SEO-friendly URLs following Google's recommendations, or underscores (_) for programming identifiers and database keys. Multiple consecutive separators are collapsed into single separators, and leading/trailing separators are trimmed.
The tool processes multiple lines simultaneously, converting entire lists of blog titles, product names, or category labels in one operation. All transformations happen client-side in your browser with instant results—no server upload, ensuring complete privacy for proprietary product names, unpublished content titles, or sensitive business data. The output is guaranteed URL-safe, cross-platform compatible, and follows industry best practices for SEO, accessibility, and system compatibility.
Tips for Best Results
- 1.For SEO-optimized URLs, use hyphen separator (-) and enable lowercase mode. Google's algorithm treats hyphens as word separators but underscores as word joiners, so "best-coffee-maker" ranks better than "best_coffee_maker" for multi-word searches. Keep URLs under 60 characters for optimal display in search results.
- 2.When creating database identifiers or API endpoints, consider using underscore separator (_) instead of hyphens to match common programming conventions. Disable lowercase if you need camelCase or PascalCase identifiers for code that follows specific naming standards.
- 3.For international content with accented characters, the tool automatically handles transliteration. After slugifying, verify results for characters that don't have direct ASCII equivalents. For product URLs, use Remove Duplicates to check for naming conflicts.
- 4.Before publishing blog post URLs, slugify titles to remove question marks, exclamation points, and special formatting. After generating slugs, use Character Counter to verify URL length stays under recommended limits for social media sharing.
