How to Resize a PDF to A4 or Letter
A PDF built for one paper standard can print badly on another. Resize PDF changes the page dimensions and scales the content to fit, helping documents move between A4, Letter, Legal, and other common sizes.

Steps
Open Resize PDF
Add the PDF whose page dimensions need to change.
Choose A4, Letter, or another size
Select the destination page size from the available options.
Scale the content to fit
Let the tool fit the existing page content to the new dimensions.
Download and inspect
Download the resized PDF and check text, tables, and margins.
Choose the destination size
A4 is common internationally, while Letter is common in the United States and Canada. Legal provides extra length for contracts and forms.
Choose the size that matches the printer or submission requirements, not simply the screen where you are viewing the document.
Review scale and readability
Changing from a larger page to a smaller page can reduce the apparent size of text. Open the result at 100% and inspect tables, footnotes, and edge content.
Resizing creates a new file and leaves the source document untouched.
