How to Convert a PDF Letter to A4by Wendy Lau
Adobe Acrobat is a program that allows you to view and create PDF files. Whether you work with text, graphics or a combination of the two, you can create a PDF file for recipients to view with no changes to formatting due to differences in operating systems or the programs that the recipients use. You can also change a PDF file's page size and make your content fit within the printer margins set for the new page size.
Open your PDF file in Adobe Acrobat.
Click on "File," and select "Print Setup."
Select "A4" from the drop-down menu for "Size" under the "Paper" section.
Click "File" and select "Print." Click on the drop-down menu for "Page Scaling," and select "Fit to Printable Area."
