Slug Generator
How to use the slug generator
- Type or paste a title, phrase or file name.
- The slug updates live - choose the separator (hyphen, underscore or none) and decide whether to keep numbers.
- Copy the result; it is immediately safe for URLs, filenames and CMS permalinks.
The generator transliterates non-ASCII letters where possible ("café" → "cafe"), strips punctuation, merges duplicates and always produces lowercase output.
Frequently asked questions
Why do URLs need slugs?
Search engines and users read readable URLs better than query strings. A clean slug like /how-to-bake-bread is descriptive, shareable and easier to type.
How are non-Latin characters handled?
Accented Latin letters are transliterated to their nearest ASCII equivalents ("é" → "e"). Characters with no ASCII equivalent are removed.
Which separator should I use?
Hyphens are the SEO convention for URLs (Google treats them as word separators). Underscores suit variables and filenames in some systems.
Does it preserve numbers?
Numbers are kept by default (e.g. "2026" in a year slug) but can be dropped with the toggle for purely word-based slugs.
Is it safe to use slugs in any CMS?
Yes - the output is lowercase, ASCII-safe and free of reserved characters, so it works in WordPress, Astro, Next.js, Ghost and most others.
What characters are allowed in an SEO URL slug?
Standard SEO slugs use lowercase alphanumeric characters (a-z, 0-9) separated by hyphens. All accents and special punctuation are removed or transliterated.
How are accented characters (like é or ö) handled?
Accented characters are automatically transliterated into their base Latin equivalents (e.g., "café" becomes "cafe") for optimal URL compatibility.
Can I change the separator from a hyphen to an underscore?
Yes. You can choose whether to separate slug words with hyphens, underscores, or remove separators entirely.
