ConverterLowercase to Uppercase
Change lowercase or mixed-case text to uppercase for short labels, headings, codes, or display text that intentionally uses capitals. The operation changes caseable letters without converting the text into another format.
Uppercase Without Reformatting
JavaScript applies its default uppercase mapping to the entered string. Digits, punctuation, and spaces remain, while letters with an uppercase mapping are transformed.
Uppercase can improve consistency for short labels, but long all-caps passages may be harder to read. This tool does not decide which typography is appropriate for the destination.
