Uppercase Converter
Uppercase, also called all caps, is text in which every letter is a capital letter. This uppercase converter changes each lowercase letter to its capital form, accented letters included, and leaves numbers, punctuation, spacing, and line breaks exactly as you typed them, so lists and paragraphs keep their layout.

Uppercase Converter rules
- Every lowercase letter becomes its capital form, in any alphabet that has capital letters (Latin, Greek, Cyrillic).
- Capital letters, numbers, punctuation, symbols, and emoji stay as they are.
- Spacing and line breaks are kept, so paragraphs and lists keep their layout.
- A few letters change length: the German ß becomes SS, following the Unicode case rules your browser applies.
- Converting to uppercase loses the original capitalization of names and acronyms. Another case tool cannot restore it; use Undo to get your original text back.

When to use Uppercase Converter
Editors and writers
Short labels, kickers, and notices where your house style calls for all caps.

Developers
Normalizing codes such as airport, country, or currency codes before comparing them.
Data cleanup
Making a column of state abbreviations, SKUs, or postal codes consistent before import.
FAQ
How do I change lowercase to uppercase without retyping?
Paste your text into the editor above. Every letter is converted to uppercase as you type or paste, and the Copy button puts the result on your clipboard.
Does the uppercase converter change numbers or symbols?
No. Only letters change. Numbers, punctuation, symbols, emoji, spaces, and line breaks stay exactly as they were.
Does it work with accented letters and other alphabets?
Yes. Accented Latin letters (é becomes É) and other alphabets with capital letters, such as Greek and Cyrillic, are converted. The German ß becomes SS.
How do I change all caps back to normal text?
Use Undo to get your original text back. If you only have the all-caps version, the Sentence Case Converter or Title Case Converter rebuilds the capitals, but names and acronyms need checking by hand.
Is there a limit on how much text I can convert?
You can convert up to 100,000 characters at a time.
Is my text uploaded anywhere?
The conversion runs in your browser, so your text is not uploaded to a server to be converted.
