How to let people edit text and not the images

You need to be really on top of this if you are going to be selling the result, because there can be a LOT of user frustration. You especially need to be on top of product names.

You need Acrobat Pro (or Acrobat Standard) to add form fields to a PDF. InDesign can be used but it isn't usually satisfactory for your purposes because you can't choose fonts for form fields.

Form fields can be filled in SOME PDF products, including the free Acrobat Reader. RECENT versions of Reader can save them: how recent depends on stuff you do. Other PDF products may:

- work as well as Acrobat for some purposes

- not allow form filling at all

- fill in forms but not be able to save them

"Other PDF products" is very relevant. Almost all new purchases of a computer, tablet or phone include a PDF viewer, NOT one made by Adobe. You have to REALLY motivate people if you want them to download more software to do what they think they can already do. And many get very confused. For example, Chrome views PDFs and will NOT use Reader. But many people assume that installing Reader will change that.

It isn't called editing in Reader, it's called Filling (a form). You can't do anything in Reader until you've made form fields.

Bear in mind most software will ignore the locks. Not really worth the effort.

If you make a form and put the text into fields, you can put on security where users and enter text into the form, but can't make changes to the pictures and layout without the password.

People do this when they sell pre-made invitations, for example.

Is that what you are thinking?

You need the paid version of Acrobat to make forms. You can get a free 7-day trial to make sure it works for you.
