Question 1

Do I need at least two PDFs to use merge?

Accepted Answer

Yes. The merge button stays disabled until at least two PDFs are selected.

Question 2

Does the merged file keep the order shown in the upload list?

Accepted Answer

Yes. Pages are copied into the new PDF in the same order shown before you start the merge.

Question 3

What happens if I enable "Compress files before processing"?

Accepted Answer

Each PDF is compressed before merging when it helps. If compression does not improve a file, the original file is used automatically.

Question 4

Can I merge more than two PDF files into one document?

Accepted Answer

Yes. The tool only requires at least two PDFs to start, but you can add more and merge them into a single output file.

Question 5

Does merging change page size or page orientation?

Accepted Answer

No. The merger copies pages in order and keeps each page at its original size and orientation instead of normalizing the whole document.
