What Is the Resize PDF Pages Tool?

The Resize PDF Pages tool allows you to change the dimensions of PDF pages without changing the original document content. You can convert pages to standard sizes such as A4, Letter, Legal and A3, or enter a custom width and height in millimetres.

This free PDF tool is useful when a document has the wrong page size, inconsistent dimensions, oversized pages or content that does not fit common printing standards. It can resize every page in a PDF or only selected pages.

The tool also provides portrait and landscape orientation, page margins and several methods for fitting the original content onto the new page size. After processing, it creates a new PDF while leaving the original document unchanged.

Real Before and After Example

Before Resizing

A 12 page PDF uses Letter size. It needs to be printed on A4 paper, but the printer scales the pages unevenly and adds inconsistent white space.

After Resizing

The user selects All Pages, A4, Portrait, Fit to Page and a 20 point margin. The new PDF contains consistent A4 pages with all original content visible.
