What is a flattened PDF?
To flatten a PDF is like driving a road roller on the ground, everything ends up in the same layer, so is your PDF.
To be more specific, if you flatten an annotated PDF, all the annotations will be “integrated” into the original content. For flattened PDF forms, all the interactive elements such as text fields,check boxes, radio buttons, list boxes are no longer fillable or selectable.
Why should I flatten PDFs?
There are three reasons:
1. For security.
When you spend a lot of time annotating PDFs or filling out forms and need to forward the completed ones to others, you certainly don’t want your PDF to be edited. Even more serious is that if they are business forms, you absolutely would like to avoid this from happening. In this case, flattening is a safer way to protect your PDF documents to an extent.
2. For printing.
If you want to print the annotations you made to the PDF, you need to flatten the PDF first, otherwise, you may waste paper in vain and waste time dealing with this simple problem.
For the receiver, the flattened copy is easier to open and read because it is smaller in size and allows faster rendering. You may also leave a more considerate impression for others.
