About the Slug Generator
A slug is the URL-friendly version of a title or name — lowercase, no special characters, words joined by hyphens or underscores — used in blog post URLs, file names, and database identifiers.
This tool converts any title or phrase into a clean slug, handling accented characters, punctuation, and repeated separators automatically.
How it works
- Type or paste your title or phrase into the input box.
- Choose a separator — hyphen or underscore.
- Click Generate to get a clean, URL-safe slug ready to use.
Common use cases
- Blog post URLs: Turning a post title like 'Hello World! This is a Post' into `hello-world-this-is-a-post` for a clean, readable URL.
- File naming: Converting a document title into a safe filename with underscores instead of spaces or punctuation.
- Database or CMS slugs: Generating a consistent identifier field from a product or category name entered by a content editor.
Frequently asked questions
How are accented characters like é or ü handled?
The tool normalizes accented characters to their closest plain-ASCII equivalent (é → e, ü → u) before slugifying, so international titles still produce clean, readable slugs.
What happens to punctuation like ! or ?
Any character that isn't a lowercase letter or digit is treated as a separator and collapsed into a single hyphen or underscore, so `Hello, World!` becomes `hello-world`, not `hello--world-`.
Will the slug ever start or end with a separator?
No — leading and trailing separators are automatically stripped, so a title with leading punctuation still produces a clean slug without a stray hyphen at either end.
Why choose underscore over hyphen?
Hyphens are the SEO-standard convention for URLs (search engines treat them as word separators), while underscores are sometimes preferred for filenames or systems where hyphens have a different meaning — use whichever your target system expects.
