Uppercase Converter
Every letter becomes a capital, everything else — punctuation, numbers, line breaks — stays exactly where it was. Click UPPERCASE above and the text converts in place.
Tip: select part of your text first and only the selection is converted. Conversions happen in place and are fully undoable here — nothing leaves your browser.
When uppercase is the right case
All caps earns its place in short bursts: headings, labels, buttons, acronyms and form fields like country or state codes. It is a poor choice for paragraphs — a wall of capitals reads slower and, online, sounds like shouting. If your text came out of a caps-lock accident, you probably want the Sentence Case converter instead; if it arrived SHOUTING and you need it calm, run it through lowercase first and then Sentence case.
What the conversion does and does not touch
| Input | Output |
|---|---|
| hello, World! 123 | HELLO, WORLD! 123 |
| don't stop | DON'T STOP |
| café — naïve | CAFÉ — NAÏVE |
Accented letters convert with their proper capitals (é → É), because the conversion uses full Unicode case mapping rather than an A–Z-only swap. Characters without a case — digits, symbols, emoji — pass through unchanged.
