`decrypt()` is a `PyPDF2` function that allows developers to remove password-based encryption from a PDF file. It's useful for automating the process of decrypting PDF files in Python, which can be necessary when working with encrypted files or when password protection is no longer needed. With `decrypt()`, developers can easily remove encryption from a PDF file in their Python scripts.

We have encrypted file encrypted-pdf.pdf from the previous chapter. Let's decrypt and save it into decrypted-pdf.pdf file.

The encrypted-pdf.pdf file:

The decrypted-pdf.pdf is the copy of the example.pdf file:

In this project, we will study how to manipulate and extract data from PDF files, such as text and images, and combine multiple PDF files into a single document.
