How the Lowercase Converter works
Each uppercase letter is replaced by its lowercase form using Unicode rules, so É becomes é and Σ becomes σ (or ς at the end of a word). Characters without a case, such as digits, punctuation, Chinese and Arabic, are unchanged.
The Turkish capital I should become the dotless ı, while the dotted İ becomes i. The standard rules would turn I into i, which is wrong in Turkish and Azeri, so select the language in the options if you need it.
Line breaks, tabs and spacing are preserved.
How to use it
- Paste your text.
- Choose language rules if you write Turkish, Azeri or Lithuanian.
- Copy the result.
Example
Latin and Greek capitals are lowercased; the final Greek sigma becomes ς.
Input
HELLO WORLD. CAFÉ ΟΔΥΣΣΕΥΣ
Result
hello world. café οδυσσευς
Frequently asked questions
Will it lowercase names and acronyms too?
Yes, every letter is lowercased. If you need only the first letter of each sentence capitalised afterwards, run the result through the Sentence Case Converter.
Is lowercase conversion safe for email addresses and URLs?
Domain names are case-insensitive, but the part of an email address before the @ and the path of a URL can be case-sensitive on some systems. Check before lowercasing text you intend to use as an identifier.
Why does Turkish text come out wrong?
Without language rules, I becomes i. Select Turkish in the options so I becomes ı and İ becomes i.
