How do I make sure my combined PDF has all the files in the correct order?

After you add your files in the 'Combine files' window, you will see small pictures (thumbnails) of each file. Drag these thumbnails up or down to change their order. The files will be put together in the PDF from the top thumbnail to the bottom thumbnail.

How is combining files different from just attaching files to an email?

Feature Combine Files Attach to Email. Result One single PDF document. Multiple separate files. Viewing Scroll through all content continuously. Open each file separately. Navigation Use bookmarks to jump between original documents. No built-in navigation between files. Purpose Create a unified, organized document or packet. Send multiple documents as they are.

about this task

After you add your files in the 'Combine files' window, you will see small pictures (thumbnails) of each file.
Drag these thumbnails up or down to change their order.
The files will be put together in the PDF from the top thumbnail to the bottom thumbnail.

Keeping 'Preserve Bookmarks' on is important because it makes your new, combined PDF easy to use. Each original file will get its own bookmark in the new PDF. This means you can quickly click on a bookmark to jump to the start of any of the original documents, making navigation simple.

Combining files usually does not make the PDF smaller. If your combined PDF is too large, you should compress it after you have finished merging. Acrobat has a 'Optimize PDF' or 'Reduce File Size' feature that can help make the file smaller without losing too much quality.

Feature	Combine Files	Attach to Email
Result	One single PDF document.	Multiple separate files.
Viewing	Scroll through all content continuously.	Open each file separately.
Navigation	Use bookmarks to jump between original documents.	No built-in navigation between files.
Purpose	Create a unified, organized document or packet.	Send multiple documents as they are.

Page numbers in original files are part of each file's content. When you combine files, Acrobat puts these contents together. It does not automatically change the page numbering from the original files. So, if each original file started with page 1, your combined PDF will show 'page 1' multiple times. You need to add new, continuous page numbers after combining if you want them to flow correctly.
