How to Resize PDF Pages
This tool standardizes every page in a PDF to A4, US Letter or US Legal dimensions. It can help prepare mixed-size documents for printing, archiving or workflows that require a consistent page canvas.
Example
If a PDF contains pages with several different dimensions, selecting A4 changes each page canvas to approximately 595 × 842 points so the document uses one consistent size.
Factors That Affect the Result
Changing the page canvas does not automatically scale or reposition existing page content. Content that was designed for a different size may appear with extra space or extend beyond the new page boundary, so review the output carefully.
Frequently Asked Questions
Which page sizes are available?
A4, US Letter and US Legal.
Does resizing automatically scale the content?
No. This tool changes page dimensions, not the content scale.
Does the original PDF change?
No. A new resized PDF is created.
Page Size, Scaling and Output Quality
Resizing a PDF page changes its page dimensions, but page size and content scaling are separate operations. If content is scaled, text and graphics change proportionally; if only the page box changes, existing content can gain margins or be clipped. Preserve aspect ratio when distortion is not intended.
