Should I use ä→a or ä→ae?

German convention is ae/oe/ue/ss and German readers expect `muenchen`; most other languages expect the plain vowel. The "German umlauts" toggle switches between the two.

What is the max slug length?

No hard limit, but 60–80 characters is a common recommendation for SEO and readability. Set a max length and the tool cuts at the last separator inside it rather than mid-word.

How does uniqueness work?

Paste the slugs already in use; any new slug that collides (or repeats within your batch) gets a `-2`, `-3`… suffix. Templates are applied before the check, so `2026/09/my-post` and `my-post` are treated as different.

Can I use a custom separator?

Yes. Hyphen is the default (and what search engines treat as a word boundary); underscore and period are also available.

Slug Generator

Convert titles and phrases into URL-safe slugs, one per line, with a before/after table. Transliteration maps accented Latin, German umlauts (ä→ae optional), Scandinavian, Polish, Turkish, Czech, Romanian and Vietnamese letters plus Cyrillic, Greek, Arabic and Hebrew to ASCII, or keep Unicode letters for CJK URLs. Remove English/German/French/Spanish stop words, split camelCase identifiers, truncate at a word boundary, add date or ID prefixes with a template, and make slugs unique against an existing list with -2/-3 suffixes. A reverse mode turns slugs or URLs back into titles.

How to use Slug Generator

1Paste one title per line; slugs appear live in the output and in the before/after table.
2Choose the separator, transliteration, stop-word language, camelCase splitting and max length in the options.
3Add a template such as {yyyy}/{mm}/{slug} and paste existing slugs to avoid collisions.
4Copy a single slug, the whole list, or export as JSON or CSV. Use Slug → title to reverse.

Frequently asked questions

Accented Latin letters are decomposed with Unicode NFKD and stripped (`café` → `cafe`). Letters without a decomposition and other scripts go through a transliteration table: `Straße` → `strasse`, `Łódź` → `lodz`, `Съешь` → `sesh`, `Καλημέρα` → `kalimera`. Scripts the table does not cover (CJK, Thai) are dropped unless you enable "Keep Unicode letters".
