How do I make sure my files are in the correct order when using Combine Files?

After you add all your files in the Combine Files tool, you will see small pictures (thumbnails) of each file. Drag these thumbnails up or down to change their order. The files will be combined from the top thumbnail to the bottom thumbnail. Always check the final PDF to ensure the order is correct.

about this task

After you add all your files in the Combine Files tool, you will see small pictures (thumbnails) of each file.
Drag these thumbnails up or down to change their order. The files will be combined from the top thumbnail to the bottom thumbnail.
Always check the final PDF to ensure the order is correct.

The 'Preserve Bookmarks' option in Combine Files creates a bookmark for each original file you add to your new PDF. This is important because it makes your combined PDF easy to navigate. Each original file becomes a main section you can quickly jump to. Without it, your large combined PDF would be harder to browse, especially if it has many different documents inside.

No, if your original files already have page numbers, Combine Files will not make them continuous. Each file's page numbering will restart. After combining, you will need to add new, continuous page numbers to the entire combined PDF. This ensures all pages have unique and sequential numbers.

Combining files rarely makes the PDF smaller. Often, the size stays the same or even grows slightly. This happens because Acrobat is putting all the data from different files into one. To make your combined PDF smaller, you should compress it after you have finished combining the files. Acrobat has a 'Optimize PDF' or 'Compress PDF' feature that can reduce the file size.
