![]() ![]() Now let's define our main code: if _name_ = "_main_": It takes the PDF input_file and produces the compressed PDF output_file. This function compresses a PDF file by removing redundant information and compressing the data streams it then prints a summary showing the compression ratio and the size of the file after compression. "Compression Ratio": "".format(i, j) for i, j in ems())) "Output File": output_file, f"Compressed Size": get_size_format(compressed_size), "Input File": input_file, "Initial Size": get_size_format(initial_size), Ratio = 1 - (compressed_size / initial_size) # Reduce PDF size by removing redundant information and compressing data streamsĭoc.Save(output_file, SDFDoc.e_linearized)Ĭompressed_size = os.path.getsize(output_file) ![]() ![]() Initial_size = os.path.getsize(input_file) Now let's define our core function: def compress_file(input_file: str, output_file: str): Next, let's define a function that prints the file size in the appropriate format (grabbed from this tutorial): def get_size_format(b, factor=1024, suffix="B"):įor unit in : Open up a new Python file and import necessary modules: # Import Librariesįrom PDFNetPython3.PDFNetPython import PDFDoc, Optimizer, SDFDoc, PDFNet COMPRESS PDF FREE INSTALLTo get started, let's install the Python wrapper using pip: $ pip install PDFNetPython3=8.1.0 COMPRESS PDF FREE HOW TORead also: How to Compress Images in Python. You can check this tutorial for compressing and archiving files. Note that this tutorial only works for compressing PDF files and not any file. The goal of this tutorial is to develop a lightweight command-line-based utility through Python-based modules without relying on external utilities outside the Python ecosystem (e.g., Ghostscript) that compress PDF files. We will use the free trial version of this SDK for this tutorial. It offers two types of licenses depending on whether you're developing an external/commercial product or an in-house solution. Developers use PDFTron SDK to read, write, and edit PDF documents compatible with all published versions of PDF specifications (including the latest ISO32000). With PDFTron components, you can build reliable & speedy applications that can view, create, print, edit, and annotate PDFs across various operating systems. PDFNetPython3 is a wrapper for PDFTron SDK. In this tutorial, you will learn how to compress PDF files using the PDFTron library in Python. As a result, it significantly increases effectiveness and shareability.
