Good to know

Convert to Upper Case works like a quick command for selected or pasted text: in, capitalised, out. It is well suited to headings and labels where a uniform capital style is wanted. After converting, glance over locale-sensitive letters, since a few scripts capitalise in ways that may need a manual check.

Frequently asked questions

Can I convert just a pasted snippet?

Yes. Whatever you paste is converted in full, so a single snippet works fine.

Does it touch punctuation?

No. Only letters are capitalised; punctuation and numbers are preserved.

Is there a size limit?

Very large pasted text depends on your browser memory; for huge files, split the text into smaller parts.
