What is a URL slug?
A URL slug is the part of a URL that identifies a specific page in a human-readable form. For example, in 'example.com/blog/my-blog-post', 'my-blog-post' is the slug. It makes URLs easier to read, share, and remember.
How does slug generation work?
The slug generator converts text to lowercase, removes diacritics and special characters, replaces spaces with hyphens, and strips any non-alphanumeric characters to create a clean, URL-friendly slug.
Why are slugs important for SEO?
Slugs improve SEO by making URLs readable and descriptive. Search engines prefer clean URLs with relevant keywords. A good slug helps both users and search engines understand what a page is about before clicking.
What characters are removed from slugs?
Special characters like !@#$%^&*() and diacritics (accents) are removed. Only letters, numbers, and hyphens are kept. This ensures the slug is safe for URLs across all browsers and systems.
Can I customize the separator character?
Currently, the tool uses hyphens (-) as the default separator, which is the SEO best practice. Hyphens are preferred by search engines over underscores for word separation in URLs.
Is this slug generator free to use?
Yes, this tool is completely free with no usage limits. You can generate unlimited slugs without registration or account creation.
Is my data safe when using this tool?
Absolutely. All processing happens locally in your browser using JavaScript. No text is sent to any server, ensuring complete privacy and data security.
What is case sensitivity mode?
When enabled, the original letter case is preserved in the slug instead of converting everything to lowercase. However, lowercase is recommended for URLs as most web servers treat URLs as case-sensitive.
Can I generate slugs for non-English text?
Yes, the tool handles Unicode text and converts accented characters to their base forms. For example, 'café' becomes 'cafe', 'naïve' becomes 'naive'. Non-Latin scripts may require transliteration.
What is the ideal slug length?
While there's no strict limit, keep slugs concise and descriptive, typically 3-5 words. Shorter slugs are easier to share and less likely to be truncated in search results or social media.
What's the difference between a slug and a permalink?
A slug is just the page identifier part of the URL, while a permalink is the complete, permanent URL to a resource. The slug is a component within the permalink structure.
Can I use underscores instead of hyphens?
While technically possible, hyphens are strongly recommended. Google treats hyphens as word separators but underscores as word joiners, making hyphens better for SEO and readability.
How to Use Slug Generator
Turn any title or phrase into a clean, SEO-friendly URL slug without leaving your browser. Spaces, special characters and diacritics are stripped locally, so your text never leaves the page.
- Type or paste your title into the Text field; the Slug field below updates as you type.
- Choose a Separator — - (hyphen), _ (underscore) or . (dot) — to match your URL convention.
- Keep Lowercase enabled so the slug contains no capital letters, as most URLs expect.
- Turn on Transliterate to convert accented characters like é or ü into plain ASCII equivalents.
- Enable Trim dashes to remove leading and trailing separators from the finished slug.
- Copy the result from the Slug field straight into your CMS or router configuration.
Hyphens are the search-engine-friendly choice — Google treats them as word boundaries, while underscores join words together.
