Uppercase online

How it works

Titles, acronyms, legal notices: convert to uppercase in one click

Composing a section heading, a marketing subhead, a dropdown menu, or a legal notice entirely in uppercase by hand is slow and error-prone. Paste the text, click, copy: the uppercase pass becomes a two-second action, no Caps Lock and no full word processor needed.

Accents preserved: É, À, Ç do not become E, A, C

Accents are preserved in uppercase (É, À, Ç, Ñ, Ü) as required by French and international typography rules. Many tools, including some word processors, strip accents when uppercasing — here they are kept, which avoids manual fixes after the fact.

What uppercasing does not change

Numbers, punctuation, emojis, and URLs stay untouched — only the case of alphabetic letters changes. Word order and formatting (line breaks, spacing) are preserved exactly.
