about this task

Save the combined PDF.

When you combine PDFs, 'Preserve Bookmarks' keeps the original bookmarks from each file. This is important because it makes your new, larger PDF easy to navigate. Each original file will show up as a top-level bookmark, so you can quickly jump to different sections without scrolling through hundreds of pages.

No, if your original files already had printed page numbers, combining them will likely result in restarted page numbers for each new section. For example, if you combine two files, both starting at page 1, your combined PDF will have two sections that both start at page 1. To fix this, you will need to add continuous page numbers to the combined PDF after you merge it. This ensures a smooth flow of numbering across the entire document.

Combining files rarely makes the overall file size smaller because it mostly just puts the existing data together. It does not automatically compress or optimize the content. If you want a smaller file, you should compress the combined PDF after you have finished merging all the documents. This separate step helps reduce the file size without losing quality.
