Portable Document Format
Adobe's fixed-layout document format from 1993, an ISO standard (ISO 32000) since 2008. It embeds fonts and images so each page looks the same on every device. Use it for documents you want to send, print or archive without the layout shifting.

EPUB
The open e-book standard, now maintained by the W3C, that packages XHTML, CSS and images in a ZIP archive so text reflows to fit the screen. Use it for books read on e-readers and in apps such as Apple Books and Kobo.
