Convert Text to UPPERCASE Online — Free

Paste it into the input field, press CONVERT TO UPPERCASE and use COPY TO CLIPBOARD to take the result. Nothing needs retyping, and your original stays in the top field while the tab is open so you can adjust and run it again.

Caps Lock only affects what you type next; it does nothing to text you already have. Here an existing string — pasted from an email, a spreadsheet or a chat — is converted in a single press, all of it at once.

Unicode case rules apply, so accented Latin and Cyrillic letters raise correctly. German ß expands to SS in upper case per the standard, which is browser behaviour rather than a bug on this page.

Not here — this page only goes one direction. Use the lowercase converter in the same text tools section. Note that a round trip will not restore where the original capitals were; that information is lost on the first pass.

All-caps text removes the distinctive shape of words, so readers can no longer recognize them at a glance and reading slows down. In messages and forums it also reads as shouting. Keep caps for a headline, a button or a short accent.

Yes, that is a common use. ISO 4217 currency codes, country codes and most promo code formats are written in capitals. Paste a column of values, convert, and paste it back — line breaks are preserved line for line.

It stays in your browser. The page does not send field contents to a server; a small script on the page does the conversion. Closing the tab leaves nothing stored anywhere and nothing to recover.
