FAQ
Does the German ß become SS?
Yes. Following standard Unicode rules, ß becomes SS in uppercase. Other letters are converted one to one.
Is my text uploaded anywhere?
No. The conversion happens in your browser, so your text never leaves your device.
Does it work with accented and non-English letters?
Yes. Letters such as é, ü and ß are converted correctly, as are letters from other alphabets that have upper and lower case.
Can I switch to another conversion?
Yes. Use the buttons above the text to switch between lowercase, UPPERCASE, capitalizing the first letter of each line, Capitalize Each Word, Sentence case and the programming styles (camelCase, snake_case and more). Your text stays in place.
