Change PDF pages to A4, Letter, or any size, and make every page the same size.
Resize PDF puts every page on the paper size you choose, such as A4, Letter, or a size you type, and can make a mixed document one size. It first lists the page sizes the document holds, with a count for each, so you can see why it prints unevenly.
Open the PDF and read the size report. A merged file often holds A4, Letter, and slide pages side by side.
Pick a target: a standard paper size, a custom size, the first page, the most common size, or a percentage. Then pick how the content fits.
Check the preview of one changed page, export, and print a test page before you print the whole document.
Yes. The pages are scaled as they are, not turned into images, so text stays selectable and searchable and drawings stay crisp at any zoom.
Yes. Links, comments, and form fields move and scale with the content, and form fields keep working.
The content and the new paper have different proportions. Fit keeps all the content and fills the gap with white. Choose Fill to remove the bars, at the cost of cutting off the edges.
Match the most common size. It is usually the size most of the document already has, so the fewest pages change.
