Combining files only duplicates the first page onto every page

[Mario31659908lv5i]

I have tried every way possible to combine a group of pdf documents (1 page each, about 100 of them) into one pdf. Every time I do, each and every page is a duplicate of the first page. When it's processing it looks fine and I can tell it is processing the different pages but when I save the file and then open it, all of the pages are identical. It just duplicates the first document over and over. Help

Are these forms? Do they have form fields with the same name in all the fields?

If so, you have to flatten them before merging them.

I read that somewhere just dont know how to do that they are the same form just filled out with different information. Thnaks for the help.

It can be done using a simple script, namely:

this.flattenPages();

You can run this code from an Action (if you have Acrobat Pro) on multiple files, and then merge them. Just be aware this is NOT reversible, so you might want to keep a backup copy of the editable files, just in case.
