If you have a PDF file that is combined from PDF pages or images in different sizes, you can use a simple trick to make all pages the same size.
The combined PDF pages not in the same size issue resulted from the original images not in the same DPI or the PDF pages not at the same size.

Content may be scaled up or down, which can affect the readability and layout. Elements like images, text, and graphics could be stretched, compressed, or cropped, depending on the method used.
It depends on which paper size you choose when you’re printing or scalling the file, make sure to find one that has same aspect ratio as the original content.
It can. Resizing pages may potentially disrupt the alignment of bookmarks and links. It’s important to check these elements after resizing and adjust them if necessary.
PDFgear software supports batch processing, which allows you to apply the same resizing settings to multiple PDF files at once.
The best page size depends on your intended use for the PDF. For printing, standard sizes like A4 or Letter are common. For on-screen viewing, you might choose a size that best fits the majority of content in your combined PDF to minimize scaling.
