FAQ

about this task

Open Adobe Acrobat and go to Combine files.
Add all the documents you want to merge.
Arrange them in the right order.
Make sure bookmarks are on.
Click Combine and save the new PDF.

Preserve Bookmarks means that each file you add will become a main bookmark in the new PDF. This helps you and others quickly find and jump to each part of the combined document, making it easier to use.

After combining, the page numbers inside the new PDF might restart at page 1 for each file, because the original files had their own numbering. If you want one set of page numbers for the whole PDF, you need to add continuous page numbers after combining.

This happens because one or more source files may have problems inside, like a bad structure. Acrobat might get stuck or just repeat the first file. To fix this, save each file again with Save As, add them one at a time, or use Repair Installation to fix Acrobat.
