How do I combine several PDFs into one file in Adobe Acrobat?

Open Adobe Acrobat and select Combine files. Add the PDFs you want to join. Arrange them in the order you want. Click Combine and save your new PDF.

If my merge only shows the first file many times, what should I do?

Save each source file again using Save As to refresh it. Try adding files one by one instead of all at once. If it still fails, use Help > Repair Installation in Acrobat.

about this task

Open Adobe Acrobat and select Combine files.
Add the PDFs you want to join.
Arrange them in the order you want.
Click Combine and save your new PDF.

Preserve Bookmarks means that each file you add will get its own bookmark in the new PDF. This is useful because it lets you quickly jump to each file or section inside the large combined PDF, making it easier to find what you need.

Save each source file again using Save As to refresh it.
Try adding files one by one instead of all at once.
If it still fails, use Help > Repair Installation in Acrobat.

The order matters because Acrobat puts the files in the new PDF from top to bottom, just like you arrange them. If you want the files to appear in a certain sequence, you must drag and drop them into that order before you combine. This helps keep your document organized and makes sense to people reading it.
