Change the page size of a PDF
Turn a Letter document into A4 (or the other way round), make every page the same size, or scale a PDF to A3 or A5, keeping its proportions.

or pick a file from your device
- Open the PDF.
- Choose the new size and the orientation. Automatic keeps each page's own orientation.
- Press Resize and download it.
Scaled, never stretched
Each page is placed on the new size as vector content and scaled by the same factor in both directions, so nothing is stretched, cropped or re-compressed. If the proportions differ, the page is centred with white space around it.
It is the quickest way to fix documents that print with odd margins because they were made for a different paper size.
Worth knowing
Links and form fields are not carried over to the resized pages.
Password-protected PDFs must be unlocked first.
