How do I use Combine files to make one PDF from many documents?

Open Acrobat and go to Combine files. Click Add files and select all your documents. Drag to set the order you want. Click Combine to make a single PDF. Save your new PDF.

If my source files have different page numbers, what will happen after I combine them?

Each file keeps its own page numbers, so numbering restarts in the combined PDF. This can confuse readers if they look for pages by number. To fix, add new page numbers after combining for one continuous count.

Preserve Bookmarks keeps each original file as a top-level bookmark in the combined PDF. This makes it easy to find and jump to each part. It helps you and others quickly go to the section you need, especially in large packets.

Each file keeps its own page numbers, so numbering restarts in the combined PDF.
This can confuse readers if they look for pages by number.
To fix, add new page numbers after combining for one continuous count.

This happens when one or more source files have structure problems. Acrobat may only output the first file many times or hang forever. To avoid this, re-save each file with Save As to refresh them before combining. This helps Acrobat read each file properly.
