FAQ
What is a slug?
A slug is a URL-friendly string made up of alphanumeric characters and separators like hyphens. For example, "Hello World!" becomes "hello-world". Slugs are used in blog post URLs, file names, and database keys.
How are accented characters handled?
Accented characters like é and ü are normalized via NFD decomposition and stripped of their diacritics, converting them to their base forms (e and u). This produces clean ASCII-safe slugs.
What happens to Japanese or other CJK characters?
By default, hiragana, katakana, and kanji are replaced with the separator. Enable "Keep Japanese as-is" to preserve CJK characters in the slug output.
Is my data sent to a server?
No. All processing happens entirely in your browser.
