Slug Generator
Convert text to URL-friendly slugs with transliteration, custom separators, and bulk conversion.
About This Tool
A URL slug is the part of a web address that
identifies a specific page in a human-readable format. For example,
in
/blog/how-to-build-an-api
, the slug is
how-to-build-an-api
. Well-crafted slugs improve SEO by giving search engines clear
context about page content, and they make URLs easier for users to
read, share, and remember.
This Slug Generator converts any text into a clean, URL-friendly slug in real time. It handles the common challenges of slug creation: removing special characters, replacing spaces with separators, normalizing case, and collapsing consecutive separators. The result is always a safe string that works in any URL without encoding issues.
One of the most powerful features is transliteration support. The tool includes a comprehensive mapping of over 200 characters from Latin-extended alphabets (French, German, Spanish, Portuguese, Turkish, Nordic), Cyrillic (Russian, Ukrainian), and common symbols. Characters like é, ü, ñ, and ß are automatically converted to their ASCII equivalents, ensuring slugs remain readable across all systems.
The tool supports bulk conversion for generating multiple slugs at once — paste a list of titles, one per line, and get all slugs instantly. This is ideal for content management systems, blog migrations, or database seeding where you need hundreds of slugs quickly.
Advanced options include configurable separators (hyphen, underscore, dot, or custom), case modes (lowercase, uppercase, Title Case), maximum length with intelligent word-boundary truncation, number stripping, and custom find-and-replace rules. All processing runs entirely in your browser — no data is ever sent to a server.
How to Use
- Choose Single mode for one slug or Bulk mode for multiple slugs at once.
- Type or paste your text into the input area. The slug is generated in real time as you type.
- Open Slug Options to customize the separator character, case style, max length, and other settings.
- Enable Transliteration to convert accented and non-Latin characters to ASCII equivalents.
- Add Custom Replacements for domain-specific substitutions (e.g., & → and, @ → at).
- Click Copy or press Ctrl+Shift+C to copy the generated slug to your clipboard.
- In Bulk mode, click Copy All to copy every generated slug at once, separated by newlines.
FAQ
What is a URL slug?
A URL slug is the portion of a URL path that identifies a specific page in a human-readable way. For instance, in example.com/blog/my-first-post, the slug is my-first-post. Good slugs use lowercase letters, hyphens as word separators, and avoid special characters.
Why are URL slugs important for SEO?
Search engines use URL slugs as one of many signals to understand page content. A descriptive slug like /tools/slug-generator tells both search engines and users what to expect, which can improve click-through rates from search results. Google recommends using simple, descriptive words in URLs.
Is my text data safe?
Yes. All slug generation happens entirely in your browser using native JavaScript string operations. No text is ever sent to any server. You can verify this by checking the Network tab in your browser's developer tools.
What is transliteration?
Transliteration converts characters from one writing system to another. In the context of slugs, it replaces accented or non-Latin characters with their closest ASCII equivalents. For example, \u00e9 becomes e, \u00fc becomes u, \u00df becomes ss, and Cyrillic \u00ab\u0424\u00bb becomes f. This ensures slugs are universally compatible with all systems.
Should I use hyphens or underscores in slugs?
Google treats hyphens as word separators but treats underscores as word joiners. This means my-page is read as "my" and "page", while my_page is read as "my_page". For SEO, hyphens are generally recommended. Underscores are more common in programming contexts like file names and database columns.
What happens when max length is set?
When you set a maximum length, the slug is truncated to that number of characters. The tool tries to cut at the nearest word boundary (separator) to avoid breaking words mid-way. Any trailing separator is automatically removed after truncation.
Can I use this for non-English text?
Yes. With transliteration enabled, the tool handles French (\u00e9, \u00e7, \u00fb), German (\u00e4, \u00f6, \u00fc, \u00df), Spanish (\u00f1, \u00a1), Portuguese (\u00e3, \u00e7), Turkish (\u00f6, \u00fc, \u011f, \u0131), Nordic (\u00e5, \u00f8, \u00e6), Russian and Ukrainian Cyrillic, and many more character sets. Characters without a mapping are removed during slug generation.
