How to make combined pdf pages the same size.

Hello - is there an explination of how to do this for 2025.  

I followed the path through the menu is good until we get to Scalte pages to specified size.  That option does not exist for me.  

Thank you, 

for mac users

How to Make All PDF Pages the Same Size (Combined PDF, Online Free)?
(solution 2)

I get as far as the little blue wrench and there is no option to scale pages 😞

Is there a way to remove the resizing that happens in combine files to make them all the pages the same size. The 'print to pdf' option works but Acrobat Reader doesn't allow to print to pdf. Why is Acrobat so difficult and constantly changing files (sizes, rotation) when they're imported? Wasting so much time to get the files back to where they started 

Hi Friends, 

I lost sleep over this - it's so annoying lol. The pages are all 8.5 x 11 but the freakin images looked like they were different sizes.  

Here's what worked for me (on my MAC).  I emailed the document to myself. Then, I opened the attachment online, then I printed it as a PDF (save as PDF)- and then somehow the images of the pages were all the same size.   

Just for the heck of it, the above works also if you fill out a form and can't save it as a flattened document (bc of the security or whatever). If you do the above, it somehow works to flatten the document.   I hope this helps 🙂

Looks like this has been ongoing for years! Here's what I do to fix this  problem:

Open the scanned document in Adobe Scan App > Tap "Modify" > Tap " Resize",
select the desired page size (for example, US Lettet Portrait)
scroll through all the pages and make sure the entire page fits into the Crop Marks for the selected page size.

When ready to save the changes hit the Check Mark √ at the top of the document.

I scanned my notes and and combined all pages (scanned images) using right click contextr menu and made pdf.

I opened that pdf in acrobat pro later and replaced a page (organise pages > right click on page > insert page >selected page image)

Issue - Why this replaced page size is larger than other pages (see attachment) ? 

I want to fix this. Please tell me how to do that.

[I checked the properties of pages below it and the pixel resolution is same 2040*2807]

[I made the pdf file of that single page and then inserted it but still it's larger]

Thanks & regards.

I end up opening the combined file in Preview Mac Built-in App. Then go to print, and under the PDF dropdown in the bottom left, save as pdf, and this saved file has the pages as the same page, per the printer settings in Preview.

George,  I just signed up for Adobe Acrobat on my iPad. The subscription version. I am combining 2 jpegs/pdf's.  The are actually the same size as PDFs. It's a book and it's cover. I have to use the compress function on the inside of the book because it's over 104mb. After I do that, I select add a file. It adds the cover. But the cover is waaay smaller than the book and looks silly. I read your notes about click "print" and size to fit etc, but this version on the iPad, when I do that, it doesn't even offer those options, how do I resize the cover to match the book?  When I do select "print" it in fact shows the cover as being the same size as the internal pages. But the issue is, I need to send electronic versions of the book and the cover needs to be the same size in that send.  Thank you!🙂

hello, would you help me with the fact that how can I print with fit (page sizing) without flattening of my pdf and highlights? many thanks in advance
