Slugify string

A slug is the URL-friendly part of an address that identifies a page, such as how-to-bake-sourdough in example.com/blog/how-to-bake-sourdough. Good slugs are short, readable, lowercase and contain only letters, digits and hyphens. This tool converts any title or string into a clean slug, which also works for file names and HTML IDs.

How to use it

1. Paste the title or text.
2. Copy the generated slug.

Examples

• 10 Tips for Better Sleep! becomes 10-tips-for-better-sleep
• Crème Brûlée & Café au Lait becomes creme-brulee-and-cafe-au-lait (depending on how & is handled)
• What's new in Vue 3.4? 🚀 becomes whats-new-in-vue-3-4

What slugify does

• Transliterates accented letters to ASCII: é to e, ü to u.
• Lowercases everything.
• Replaces spaces and punctuation with hyphens.
• Removes emoji and other symbols.
• Collapses repeated hyphens and trims them from the ends.

SEO best practices for slugs

• Keep slugs short and descriptive; 3 to 6 words is plenty.
• Use hyphens, not underscores. Google treats hyphens as word separators.
• Leave out dates and numbers that will become outdated, such as a year in an evergreen article.
• Stop words like a, the and of can often be removed.
• Do not change slugs of published pages without a 301 redirect, or you lose rankings and create 404 errors.

In code

Libraries such as @sindresorhus/slugify (JavaScript), python-slugify and Django's slugify do the same; make sure duplicates get a suffix like -2.
