How does the Resize PDF Pages work?
Standardise the page size of a PDF — useful when a printer expects A4, when you want to fit a deck into a Letter-sized binder, or when you're combining files of mismatched sizes. Each page is scaled (preserving aspect ratio) to fit the target size, with white margins added if the original aspect doesn't match. Choose your target from the common standards (A4, Letter, Legal, A3, A5) and decide whether orientation is preserved (auto) or forced. Conversion runs in your browser.
