If you have multiple pdfs that you want to combine into one document in Adobe Illustrator, there are a few ways to go about it. One way is to use the File > Combine Files command, which will open the Combine Files dialog box. From here, you can select all of the files that you want to combine and then click the OK button. Another option is to use the Pathfinder panel. To do this, first open the Pathfinder panel by clicking on the Pathfinder icon located in the Tools panel (or by pressing Ctrl+P). Next, select all of the files that you want to combine and then click on the Add Paths button. This will add all of the paths from each of the selected files into one path object. Finally, click on the Join button to combine these paths into one file. ..
