What does Change PDF Page Size do?

It creates a new PDF with pages resized to the selected paper size, orientation, or custom dimensions.

Which page sizes can I choose?

The tool includes A0, A1, A2, A3, A4, A5, A6, Letter, Legal, and a custom size option.

Can I set a custom PDF page size?

Yes. Choose Custom, then enter page width and height in millimeters or inches.

Can I choose portrait or landscape?

Yes. You can use Auto, Portrait, or Landscape orientation.

Will the content reflow perfectly after resizing?

No tool can guarantee perfect reflow for every PDF. Resizing can change whitespace, scaling, or page appearance, so review the result before printing or submitting it.

Can this fix mixed page sizes in one PDF?

Yes. It can help make pages use a consistent target size, which is useful for mixed-size PDFs from scans, exports, or merged files.

Should I use this instead of cropping?

Use this tool when you need a different page size. Use Crop PDF when you need to trim visible page edges.

Can I combine resized PDFs afterward?

Yes. Use Merge PDF to combine resized files into one PDF.
