FAQ

about this task

Open Combine files in Acrobat.
Add all your images.
Drag to set the order.
Click Combine.
Save your new PDF.

Bookmarks help you find each file or section quickly in a long PDF. When you combine files, keeping bookmarks lets you see where each original file starts. This makes it easier for anyone reading the packet to jump to the part they want.

Open each file and save it again with Save As.
Check that each file opens by itself.
Add files one by one to Combine files.

Combine files can have problems if a source file is damaged or not saved right. Sometimes, it only uses the first file or never finishes. This happens because Acrobat cannot read all the files properly. To prevent this, save each file again before combining or add them one by one. If the problem stays, use Repair Installation from the Help menu.
