Make transparent background opaque

[simon@skemp.co.uk]

Hi,

Is there a way in Acrobat to change a transparent background to opaque white please?

Most PDF files don't have a background. You can see that when you turn on the "transparency grid" in Acrobat's preferences:

If you want a true background, you can add one via the Tools>Edit PDF>Background feature. Just create a page that has the background color you want, and add it to every page in your document.

Thanks Karl, it's easy to add a background based on a colour only, no need to create a page.

Is there a way to create a stamp with an opaque background? I want to blot out what is underneath the stamp.
