About Uppercase Converter — Free Online Tool
Uppercase Converter hands back your text with every letter capitalised and everything else left alone.
It applies the Unicode uppercase mapping built into the browser across the whole string, so accented letters take their capital forms and other scripts follow the same rules the operating system uses. Numbers, punctuation and line breaks pass through untouched, which keeps a list a list. Capitalisation is not a reversible step — the original spelling cannot be recovered from the result, so keep the source if the distinction between a proper noun and an ordinary word still matters downstream.
The string is transformed locally and no request is made while you type.
Setting a legal disclaimer or a warning line in capitals, matching a style sheet that wants headings in all caps, normalising reference codes before they go into a sheet, and raising a single line for emphasis in a design mock-up.
