Is it possible to take multiple PDF files and make them one? And if so how?

You would have to have bought the Adobe software and not use the free read-only version. If you have the entire program, you can copy the 2nd page and paste it at the end of the first page, and continue until all files are merged into one.

Take a look at ImageMagick.

You can manipulate a lot of different file types.

I used it to combine a bunch of page scans into a single .pdf file.

You may have to do something like convert your .pdf files to .jpg files and then build a new .jpg.

Then again it may let you just merge the files.

If you are using Adobe Acrobat Pro, Go to document, Insert Pages.

If you have Adobe Acrobat, look under the DOCUMENT menu.

Good luck and Happy Computing!
