Counters describe the result. Characters are counted as Unicode code points, so one emoji counts as one character. Umlauts stay umlauts: ÄÖÜ becomes äöü, ẞ becomes ß.

What the Lowercase Converter Does

This converter rewrites text into lowercase as you type: paste into the first box and the second box shows the lowercase version immediately. The conversion uses Unicode case mapping, so German umlauts and the sharp s are handled properly instead of being stripped — Ä becomes ä, Ö becomes ö, Ü becomes ü and the capital sharp s ẞ becomes ß. Accents such as é or ç stay intact, Cyrillic letters are lowercased too, and emoji, digits and punctuation pass through unchanged. The counters describe the result: characters, words and lines. Characters are Unicode code points, so an emoji counts as one character. The optional switch trims spaces at the start and end of every line. What it does not do: it cannot turn STRASSE back into Straße, because the sharp s is lost once a word is written in capitals, and it never removes accents. Everything runs locally in your browser.
