Slugify — developer notes
Build URL-safe slugs from titles: Cyrillic transliteration, NFD diacritic strip, ASCII sanitize, separator collapse, casing, and clean max-length truncate.

How slugify works

Pipeline: trim → Cyrillic (and ß) transliteration → optional diacritic strip (NFD) → non-alphanumeric → separator → collapse → trim edges → casing → max-length truncate on a separator boundary. Live preview updates as you type. CJK and other non-covered scripts are not transliterated — they become separators and may yield an empty slug.

Options

Separator (- / _)
Hyphens for typical URL paths; underscores when you need identifier-style slugs.
Casing (lower / upper / preserve)
Lowercase is the web default; upper helps constants; preserve keeps original letter case after sanitize.
Max length (0 = unlimited)
Enter any limit up to 500 characters. 0 means unlimited. Truncation prefers cutting on a separator so you do not leave a trailing separator.
Strip diacritics
On by default — é becomes e via Unicode NFD. Turn off only if you accept ASCII-only sanitize dropping accents.

Examples

Slugify FAQ

URL slug questions

Does it transliterate Cyrillic or German ß?

Yes — Cyrillic letters map to Latin approximations (e.g. Привет → privet) and ß becomes ss before ASCII sanitize. CJK and Arabic are not transliterated in v1.

What happens with empty input?

You get an empty slug string.

Is the slug uploaded?

No — conversion stays in your browser.

Why truncate on separators?

Cutting mid-word looks ugly in URLs; preferring a separator keeps the last token whole when possible.
