about this task

After adding your files, you will see small pictures (thumbnails) of each document.
Drag these thumbnails up or down to change their order.
The Combine Files tool will merge them from the top thumbnail to the bottom thumbnail.

Preserving bookmarks is important because it makes your combined PDF easy to use. Each original file will become a top-level bookmark. This means you can quickly jump to different sections of your new, larger document, instead of scrolling through everything to find what you need.

If your original files already had page numbers, combining them will make those numbers restart with each new file. To fix this, you will need to add new, continuous page numbers to the combined PDF after it's created. This ensures the entire document has one smooth sequence of page numbers.

Action	What it does	Main Goal
Merging PDFs	Puts many separate PDF files into one single PDF document.	Combine multiple documents into one.
Compressing PDFs	Reduces the file size of a PDF document.	Make the PDF smaller for sharing or storage.

This can happen if there are hidden problems with the structure of the original files. The Combine Files tool might struggle with these issues. To prevent this, try saving each source file again using 'Save As' to refresh its internal structure. Adding files one by one can also help, or you can use the 'Repair Installation' option in the Help menu.
