This page outputs 大写 so you can paste into docs, UI, or repositories.
Will this shout my entire paragraph in ALL CAPS?
Every letter becomes uppercase. Punctuation and line breaks stay put, so a press release with mixed styling becomes uniformly loud—handy for banners, not for long articles.
Do accented characters like é or ñ survive?
Yes. The tool uppercases letters using standard Unicode rules; accents remain on the characters they belong to.
Is this the same as CSS `text-transform: uppercase`?
Very close for plain text. Paste here when you want a quick preview outside a stylesheet or when editing copy in a CMS field.
Example on this page: “Hello World” → “HELLO WORLD”. Can I try my own slogan?
Absolutely—replace the sample with your headline. The output updates as you type, so you can compare versions before publishing.
