Can I leave a file out when I set the order?

Yes. Type only the numbers you want, for example 3, 1, and any file you don't list is skipped. A number typed twice is used once.

Can I add more files after I've started?

Yes. At the order step, choose “Add more files”. The new files go to the end of the list; anything that isn't a PDF is ignored.

What happens to pages of different sizes, like A4 and Letter?

Every page is copied whole from its source file, so each keeps its own size and orientation. Nothing is resized to match the others.

Merge PDF files into one

Combine any number of PDFs into a single file, in the order you choose.

When you'd use it

Your scanner saved each page as its own file and the office wants one PDF.
A job application asks for your CV, cover letter and certificates as a single upload.
You have twelve monthly bank statements and your accountant wants them in one file.

Just say what you need

There are no menus to learn. Drop your file on pdfagents.ai and type it the way you would say it:

“merge these PDFs into one”
“combine the invoices, statement first”
“append the appendix to the report”

How it works

Drop two or more PDFs (or drop one and add the rest when asked).
Confirm the order, or type a new one like 2, 1, 3.
Download the merged PDF.

Bookmarks and form fields from the source files are not carried over.

Private, and it keeps going

Your document is opened and saved on your own device, never uploaded. When the result is ready, type the next request (rotate, compress, add a password) and it applies to the result.
