About the Uppercase Converter

Retyping a heading in capitals is a minute you do not get back, and holding shift through a paragraph is worse. Paste the text, and the uppercase version is ready to copy before you have finished reading this sentence.

The conversion is done with the language-aware rules built into your browser rather than a naive letter swap, so accented characters convert properly — é becomes É, ñ becomes Ñ — and Greek and Cyrillic work too. The German ß correctly becomes SS, which is the rule that catches out most simple converters. Line breaks, punctuation, numbers and spacing are all left exactly as you typed them.

Key features of the Uppercase Converter

Correct on accented letters

É, Ñ and Ü are produced properly rather than being left behind, because the conversion uses real Unicode case mapping.

Handles the German ß

It becomes SS, which is the correct uppercase form — the case most simple converters get wrong.

Formatting preserved

Line breaks, tabs, repeated spaces, numbers and punctuation are all left exactly as you typed them.

Links survive the conversion

URLs and email addresses are left in their original case, because a raised path or local part is a broken link.

Copy or download

One click for the clipboard, or save the whole result as a .txt file.

Frequently asked questions

Yes. The conversion uses your browser's Unicode case mapping, so é becomes É, ü becomes Ü and ç becomes Ç. Greek and Cyrillic letters convert correctly as well.
