How to resize a PDF

  1. Open the PDF resize tool and choose a PDF file.
  2. Select A4, Letter, or A3 as the target page size.
  3. Process the document and download the resized PDF.
  4. Review the layout and print preview, especially if the original page size was unusual.

What happens when you resize a PDF?

The page canvas is changed to the selected standard size and the existing page content is scaled proportionally to fit. This is useful when preparing a document for common paper sizes, but it is not a PDF crop tool: it does not let you select and trim a custom area. Check text size and margins in the output before printing.
