What is Online Slug Generator?
A slug is a URL-friendly version of a title or text string, used in web addresses to identify specific pages, blog posts, or products in a human-readable format. Slugs strip special characters, replace spaces with hyphens or underscores, and convert to lowercase, transforming titles like 'My Awesome Blog Post!' into 'my-awesome-blog-post' in the URL path. Well-crafted slugs improve SEO by including relevant keywords directly in the URL, make links more shareable and memorable, and help users understand page content before clicking. Content management systems like WordPress, Ghost, and Hugo auto-generate slugs from titles, but customizing them often requires manual editing when you need to remove stop words, adjust length, or choose separators. This tool gives you full control over slug generation with options for separator style (hyphen, underscore, or dot), lowercase enforcement, number removal, and non-ASCII character handling, all processed instantly in your browser.
How to Use
- Enter your title or text in the input field.
- Choose separator: hyphen (-), underscore (_), or dot (.).
- Toggle options: lowercase, remove numbers, remove non-ASCII.
- Click 'Generate Slug' to create the URL-friendly version.
- Copy the result for use in your URLs, CMS, or routing.
- Recent slugs are saved for quick reuse.

Frequently Asked Questions
What is a slug and why do I need it?
A slug is the part of a URL that identifies a specific page in human-readable form. For example, in 'blog.com/post/how-to-code', 'how-to-code' is the slug. Slugs make URLs user-friendly, improve SEO by including keywords, and work better than ID-based URLs like 'blog.com/post/123'.
Should I use hyphens or underscores in slugs?
Google recommends hyphens (-) over underscores (_) in URLs. Hyphens are treated as word separators by search engines, while underscores can be seen as joining words. Use hyphens for blogs and public pages. Underscores are sometimes preferred in technical contexts or file naming.
Should slugs be lowercase?
Yes, lowercase is recommended. URLs with mixed case can cause issues: servers may treat them differently, users might type them wrong, and lowercase prevents duplicate content issues (MY-POST vs my-post). Most CMS platforms auto-lowercase slugs.
How long should a slug be?
Keep slugs 3-5 words, under 50-60 characters. Shorter slugs are easier to remember, share, and look cleaner. Long slugs get cut off in search results. Focus on keywords that describe the content - remove filler words like 'a', 'the', 'and'.
What characters are removed from slugs?
Slugs typically remove: special punctuation (!@#$%^&*), symbols, emojis, and non-ASCII characters (unless kept). Spaces become separators. Only letters, numbers, and the chosen separator remain. This ensures URLs work in all browsers and systems.
Can I use non-English characters in slugs?
It depends. Enable 'Remove non-ASCII' for maximum compatibility when publishing to older systems, static site generators, or mixed hosting environments. Disable it only when your CMS and routing layer explicitly support Unicode slugs. For global compatibility, use ASCII only.
Is my text data kept private?
Yes. Slug generation happens entirely in your browser using JavaScript. Your text is never sent to any server, never stored, and never logged. The tool works offline once loaded.
When should I NOT use this slug generator?
Don't use this for generating URL paths that require transliteration of non-Latin scripts (e.g., converting Chinese or Arabic characters to Latin equivalents). This tool removes non-ASCII characters rather than transliterating them. For internationalized URLs, use a library like transliteration.js. Also skip it if your CMS already auto-generates slugs with custom transliteration rules.
