![]() 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.

Open up a new Python file and import the necessary modules: # Import Librariesįrom PDFNetPython3.PDFNetPython import PDFDoc, Optimizer, SDFDoc, PDFNet ![]() To get started, let's install the Python wrapper using pip: $ pip install PDFNetPython3=8.1.0 Read 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. This tutorial aims 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 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. Try it out!Ĭompressing PDF allows you to decrease the file size as small as possible while maintaining the quality of the media in that PDF file. You would typically create a PDF if you wanted to ensure document fidelity, to make it more secure, or to create a copy for storage.Confused by complex code? Let our AI-powered Code Explainer demystify it for you. Creating a PDF can involve compressing a file, making it take up less storage space. They can be viewed on almost all devices. PDF files aren’t typically created from scratch, but are usually converted, saved or ‘printed’ from other documents or images before sharing, publishing online or storing. It is maintained by the International Organisation for Standardization (ISO). The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. PDF stands for ‘Portable Document Format’ file.
