Unflatten PDF: The Best Method to Make Files Editable in 2024

When you are in the process of merging multiple official business files, it is essential to flatten different PDF layers, such as annotation marks and form fields. Through this process, you can merge different pages, layers, and interactive elements into a seamless, single, and non-editable file. Moreover, merging makes sure that the file is safely secure so no one gets a hold of its contents.

However, there are times when people want to restore various essential elements from a flattened file. In this case, knowing how to unflatten a PDF can help you recover the original file with every element and merged data.
