Frequently asked questions
Will punctuation be removed?
Simple case styles keep punctuation. Programming styles such as camelCase and kebab-case use words only, so punctuation and extra spaces are removed.
Does it work with non-English text?
Uppercase, lowercase, sentence, and title case work with most languages your browser supports. Word-based programming styles are designed primarily for Latin-script text.
Is my text uploaded?
No. All conversions happen locally in your browser.
