Yes. If a printer, publisher or submission portal requires A4, Letter or another standard size, resize the whole document in one pass before printing. The content is scaled proportionally and centered on the new page, so nothing is stretched or cut off.

This tool applies the new page size to every page in the file, which keeps the document consistent. If only one section needs a different size, split that section out first, resize it separately, then merge it back with the rest.

Yes. Resizing runs in your browser, so it works on a phone, tablet or computer with nothing to install, for files up to 100 MB. Download the resized PDF and check one or two pages before printing the whole document.
