Merge PDF Documents - Page size issue

[TanzenPanda]

I just merged 4 PDFs into one and that worked quickly but I noticed the 2 of the 4 documents are a different size, about 25% the size of the the other 2 documents once merged. 

These PDFs were created from a PowerBI file originally,

1. How do I get them to all be the same page size, ie fill the screen?
2. Is there a way to adjust page size in a merged file?
3. Is there a setting pre-merge I am missing?
4. Is this an issue I need to address in PowerBI possibly? Not sure here...

Appreciate the input and support as I sort this out!

BTW: I would post the file but it has confidential information included.

Hi TanzenPanda,

Thank you for reaching out, and sorry about the delay in response.

As the size of the file changes after merging them, please share the PDF you create.

Also, are the file sizes of all the PDFs the same? Would you mind sharing all the initial files that you merged?

We will try to replicate the issue on our end.

Let us know if the issue is already resolved.

Thanks,

Meenakshi
