ChatPDF, complete PDF operations with one click!

First of all, what is ChatPDF?

ChatPDF is a Python-based PDF processing tool that can be used to create, merge, split, encrypt and decrypt PDF files, and extract text and images, etc. ChatPDF provides an easy-to-use API, enabling users to complete various PDF processing tasks conveniently.

Let's take a look at how to use ChatPDF!

Install

First, we need to install ChatPDF. You can install it with the following command in terminal:

pip install chatpdf

Create PDF files

Now, let's see how to create PDF files using ChatPDF. Here is a simple example:

from chatpdf import ChatPDF

pdf = ChatPDF()
pdf.add_page()
pdf.set_font("Arial", size=12)
pdf.cell(200, 10, txt="Hello, World!")
pdf.output("hello.pdf")

This code will create a new PDF file and add a page and text to it. Finally, it will output to a file called "hello.pdf".

Merge PDF files

Now, let's see how to merge multiple PDF files with ChatPDF. Here is a simple example:

from chatpdf import merge

pdf_files = ['file1.pdf', 'file2.pdf', 'file3.pdf']
output_file = 'output.pdf'

merge(pdf_files, output_file)

The above code will merge the three files file1.pdf, file2.pdf and file3.pdf, and save the merged result to the output.pdf file.

Split PDF files

To split a PDF file into multiple PDF files, you can use the split() method of the ChatPDF library. Here is a sample code:

from chatpdf import split

pdf_file = 'input.pdf'
output_folder = 'output'

split(pdf_file, output_folder)

The above code will split the input.pdf file into multiple PDF files and save them in the output folder.

Extract PDF pages

To extract some pages from a PDF file, you can use the extract_pages() method of the ChatPDF library. Here is a sample code:

from chatpdf import extract_pages

pdf_file = 'input.pdf'
output_file = 'output.pdf'
pages = [1, 3, 5]

extract_pages(pdf_file, output_file, pages)

The above code will extract pages 1, 3, and 5 from the input.pdf file and save them to the output.pdf file.

Rotate PDF pages

To rotate PDF pages at a certain angle, you can use the rotate_pages() method of the ChatPDF library. Here is a sample code:

from chatpdf import rotate_pages

pdf_file = 'input.pdf'
output_file = 'output.pdf'
pages = [1, 3]
rotation_angle = 90

rotate_pages(pdf_file, output_file, pages, rotation_angle)

The above code will rotate pages 1 and 3 in the input.pdf file by 90 degrees and save it in the output.pdf file.

Encrypt PDF files

To encrypt PDF files, you can use the encrypt() method of the ChatPDF library. Here is a sample code:

from chatpdf import encrypt

pdf_file = 'input.pdf'
output_file = 'output.pdf'
password = 'mypassword'

encrypt(pdf_file, output_file, password)

The above code will encrypt the input.pdf file and protect it with the password mypassword. The encrypted file is saved to the output.pdf file.

Decrypt PDF files

To decrypt encrypted PDF files, you can use the decrypt() method of the ChatPDF library. Here is a sample code:

from chatpdf import decrypt

pdf_file = 'input.pdf'
output_file = 'output.pdf'
password = 'mypassword'

decrypt(pdf_file, output_file, password)

The above code will decrypt the input.pdf file and use the password mypassword to decrypt it.
