I was using Acrobat 9. I combined some PDFs into one. One or more of those PDFs was a form, with blanks to be filled out by users. Thus, my combined PDF also looked like a form. Specifically, it had a purple banner across the top that read,
Please fill out the following form. If you are a form author, choose Distribute Form in the Forms menu to send it to your recipients.I wanted to get rid of that banner. One way would have been to print the whole document to PDF, but that would have made it much larger. Among other suggestions, I liked the one pointing to the Flatten Page Content Tool. It sounded like this would provide what I needed.
To make that tool work, I needed to install a Java script. The instructions told me that installation simple required me to copy the script into an appropriate folder. The folder could be Acrobat’s App folder or its User folder, but not both. The difference was that scripts in the App folder would be available to all users, while scripts in the User folder would be available only to the individual user.
The original tipster said this would permanently flatten the fields, but that they could still be edited in Illustrator, Photoshop, etc. I didn’t care about that; I just wanted to lose the purple banner. I hit the hammer icon. It said, “Select Pages to Flatten.” I chose all. It was a large document, but the process was almost instantaneous.
About this time, I discovered that I could have just hit the button at the top left to hide that purple banner. I really knew that already. I'm sure of it. Flattening didn’t reduce the PDF size for my purposes either. OK, futile gesture.
