Convert text to uppercase
Paste your text and every small letter becomes a capital, straight away and as you type. Accented letters keep their accents.
How it works
-
Paste your text
Type or paste the text in the left box, or open a .txt file. No text to hand? Click Example.

The result appears as you type. Change the options and see straight away what changes.
-
Copy or download
Copy the result with one click, save it as a file or use it as input for a next step.
When to use it
- Headings, labels and signs that should be in capitals.
- Codes and constants, such as
MAX_RETRIES. For that, the screaming snake case converter also turns spaces into underscores. - Making a note stand out.
Hello, World! becomes HELLO, WORLD!. Numbers and punctuation don't change. Special letters are handled too: ß becomes SS, as in German.

To go the other way, use the lowercase converter. For a proper headline, title case capitalises the important words only.
