How to Resize a PDF File
It may be necessary to resize a Portable Document Format (PDF) file if the document is too big to print or the margins are not quite right. You can do this using Adobe Acrobat 9 Professional, the full version software that allows you to create, manage, and edit PDF files. You can change a PDF's page size simply for printing purposes or print it to the PDF driver to permanently change the page size.
Things You'll Need
- Adobe Acrobat 9 Professional
Open a PDF file in Adobe Acrobat 9 Professional.
Click the "Document" menu. Select "Crop Pages." This will let you adjust the PDF's viewable page area.
Click "CropBox" under "Crop Margins." Change the Margin Controls as needed.
Click "Custom" under "Change Page Size." Enter the values you want for width and height. You can also choose "Fixed Sizes" and select a new page size. Choose a page range for these settings if needed, then click "OK."
Click "File, Print." Even if you don't want to print the document, you can print to an Adobe PDF driver in order to change the page size for the file.
Click the drop-down menu under "Page Scaling," then select "Fit to Printable Area." This will reduce or enlarge the page to fit your paper size.
Select the printer you want to use. Otherwise, select "Adobe PDF" as the printer to save the file's new size. Click "OK."
