PDF Signer

This is a simple PDF signing application built with PyQt5. It simulates the process of printing, signing and the scanning a PDF document, which is still common in Germany as of 2024 :(

It allowes users to open PDF files, sign them with custom signatures, and save the signed PDFs as "screenshots of themselves", optionally in greyscale and slightly skewed (to simulate imperfect scanning).

Features

• Quickly zoom to the disired area on the page.
• Add one or more signatures.
• Save the signed PDFs as a PDF that consists of only one image object.
• Manage multiple custom signatures.
