Open Adobe Acrobat.
Go to File > Combine Files.
Click Add Files and select the PDF files you want to merge.
Arrange the files in your desired order by dragging and dropping them within the list.
Click Combine to merge the selected files into a single PDF document.
Save the new combined PDF to your preferred location.
You can preview and reorder files before combining to ensure the final PDF is in the correct sequence.
This runs in the Acrobat app - there is no separate API for this task.
Keeping 'Preserve Bookmarks' on is important because it makes your new combined PDF easy to use. Each original file will become a top-level bookmark. This means you can quickly click on a bookmark to jump to the start of any of your original documents within the big combined PDF, making it simple to navigate.
When you combine files that already have printed page numbers, Acrobat treats each file as a separate section. It doesn't automatically create one continuous numbering system across all of them. So, if each original file started with page 1, they will all start with page 1 again in the combined PDF. To fix this, you need to add continuous page numbers to the combined PDF after you merge them.
No, combining files rarely makes the PDF smaller. Usually, the size stays about the same, or it might even get a little bigger. If you need a smaller file, you should compress the combined PDF after you have finished merging all the documents.
