Frequently asked questions
How does the uppercase converter work?
Every letter in your text is converted to its uppercase form as you type. Numbers, punctuation, and spacing are left unchanged.
Will this work with accented letters?
Yes. Standard accented Latin letters (é, ñ, ü, and similar) are uppercased correctly using the browser's built-in text handling.
Is my text sent to a server?
No. The conversion happens entirely in your browser as you type — nothing is transmitted or logged.
