Content embedded, write into the PDF

Text, signature, images you added are embedded into PDF. Unlike some of other apps, which just create text boxes and annotations that flow above the content, and can be deleted in PDF Reader. It’s actually a simple PDF Editor either. Once you save the edited document as PDF, it’s not editable. But you can still save as a project file .spd for future editing.
