About this tool
Headings, labels, abbreviations, and emphasis all have their all-caps moments — but retyping a paragraph in uppercase is slow and invites typos. This converter transforms your text to UPPERCASE the moment you paste it, handling accented characters correctly.
It is also the fastest way to normalize text before comparison or storage when case should not matter. Your text never leaves the browser.

Frequently asked questions
Yes. Unicode-aware conversion correctly uppercases accented letters like é → É and ß → SS, not just basic A–Z.
No. Only letters are affected; numbers, punctuation, spaces, and line breaks pass through unchanged.
Sparingly in prose — all-caps reads as shouting. It works best for short headings, labels, abbreviations, and data normalization.
