How to Resize a Multi-Page PDF to Custom Dimensions
Question details
The user needs to resize a 237-page PDF document to a specific page size (6.125 x 9.25 inches) for uploading purposes, but lacks an eligible Adobe product to perform the action.

- Product
- Device & OS
- not provided
- Scenario
- Formatting a long PDF document to meet precise size requirements for publishing or uploading.
- Observed behavior
- Basic PDF readers cannot resize pages, requiring advanced PDF editors or specialized imposition software to adjust dimensions without distorting the content.
Ensure you have a premium PDF editor like Adobe Acrobat Pro DC or a dedicated PDF imposition tool installed, as basic PDF readers do not support altering page dimensions. Save a backup copy of your original 237-page PDF to prevent accidental data loss during the resizing process.
Resize PDF Pages Using Adobe Acrobat Pro DC Preflight Tool
Utilize the advanced Preflight feature in Acrobat Pro to apply a custom fixup for resizing multi-page PDFs to exact dimensions.
Adobe Reader does not have the capability to resize PDF pages. You must use Adobe Acrobat Pro DC to access the Preflight tool, which allows you to run specific profiles and fixups that can alter the document's page size without distorting text or images.
Launch Adobe Acrobat Pro DC, open your PDF file, and navigate to 'Tools' > 'Print Production' > 'Preflight'.
In the Preflight dialog box, click on the 'Fixups' icon (the blue wrench). Search for a fixup related to resizing or scaling pages, such as 'Scale pages to specified size' or an A4 resizing fixup.
Select the existing fixup, click 'Options', and choose 'Duplicate Fixup'. Edit the duplicated fixup to change the target dimensions to your specific requirements (e.g., 6 1/8 x 9 1/4 inches).
Save your newly created fixup, select it from the list, and click the 'Fix' button located at the bottom right corner. Choose a destination to save your resized PDF document.

Use a Dedicated Imposition Plug-in or Application
If standard tools are insufficient or you have an older version of Acrobat Standard, an imposition plug-in can accurately resize and arrange PDF pages for print.

Frequently Asked Questions
Can I resize PDF pages for free using Adobe Reader?
No, Adobe Reader is a free application designed only for viewing and adding basic comments to PDFs. It lacks the advanced editing capabilities required to change page dimensions. You need a premium editor like Adobe Acrobat Pro DC or an alternative like WPS Office.
Will resizing my PDF pages distort the text and images?
It can, depending on the method you use. If the aspect ratio of your original document differs significantly from the target size, forcing a resize might stretch or squeeze the content. Using proper scaling options or 'fit to page' settings helps maintain the original proportions.
What is an imposition plug-in for PDFs?
An imposition plug-in is specialized software that integrates with PDF editors to arrange pages on a press sheet for printing. These tools, such as Quite Imposing, are highly effective at resizing pages, adjusting margins, and setting up bleed and crop marks for professional publishing.
How do I resize a PDF in WPS Office?
You can resize a PDF in WPS Office by using the 'Print to PDF' feature. Open your document, press Ctrl + P, select 'WPS PDF' as your printer, click 'Properties', and define your custom page size before clicking Print. This will generate a new PDF with the updated dimensions.
