Slugify Text Tool

How it is calculated

The text goes through four steps. First, accented Latin letters are replaced by plain ones from a built-in table (é to e, ü to u, ß to ss, ı to i, ğ to g, æ to ae). Second, everything is made lowercase. Third, every run of characters that is not a to z or 0 to 9 (spaces, punctuation, symbols, apostrophes, existing hyphens and underscores) is treated as one gap. Finally, the gaps are replaced by a single separator, either a hyphen (default) or an underscore, and the separator at the start and end is trimmed. The tool also shows the slug's length in characters.

Only letters that are in the table survive. An accented capital that is missing from the table, and letters from non-Latin scripts such as Cyrillic, Greek or Chinese, are dropped like punctuation. If nothing remains, there is no result. Digits are kept, and word order is not changed.

Common mistakes

• Expecting non-Latin text to be transliterated. A title in Cyrillic, Greek, Arabic or Chinese is not converted to Latin letters; if it contains nothing else, the tool returns no slug.
• Expecting apostrophes to disappear. "Don't" becomes don-t, because the apostrophe is treated as a gap; remove it by hand if you want "dont".
• Assuming every accented capital is handled. Capitals missing from the table are dropped, so "ĄĘ" disappears completely while "É" and "Ç" are fine; check the output for uncommon letters.
• Expecting underscores in the input to stay. In hyphen mode they become hyphens, and in underscore mode hyphens in the input become underscores.
• Using a long title as a slug. The tool does not shorten it, so remove filler words yourself to keep a URL tidy.
