About the Resize PDF pages tool
A PDF with mixed page sizes causes chaos when printing: some pages A4, others Letter or odd sizes, so the printer produces inconsistent results. This tool standardizes every page to a single size you choose (A4, Letter, or Legal), scaling each page's content to fit the new dimensions completely without cropping or distortion.
Content is scaled proportionally to preserve its aspect ratio (no stretching or distorted squashing) and centered within the new page. All processing is in your browser with no upload. If you want to trim margins rather than resize, the Crop PDF tool fits, and to place several pages on one sheet, use the N-up tool.

Frequently asked questions
What's the difference between resizing and cropping?+
Cropping cuts parts off the page, while resizing scales the whole content to fit new page dimensions without losing any of it.
Does it keep landscape pages landscape?+
Yes, pages wider than they are tall are placed on a landscape sheet of the same standard size, keeping their orientation.
