1/15/2024 0 Comments Compress pdf file python![]() I am hoping you folks might have some more ideas. I feel like I have tried everything I can think of to reduce the final PDF file size. I have tried the compress_content_streams method from PyPDF2. I have tried reading the final PDF back into the script to pass to a fresh writer object. I have tried using writer.add_page(reader.pages) instead of merger.append(reader.pages). I am using Python 3.11 and the latest versions of each package. Then, I use PyPDF2 again to stamp the page numbers on the merged pages. I am merging the existing PDFs using PyPDF2 and creating a separate page numbers document using reportlab. The final file needs to be 20MB or less because we often send them to customers via e-mail. I need some help finding a way to reduce the final file size when my script creates PDFs. ![]() The script runs, but it is creating PDFs that are 75MB! The Excel compiler and "by hand" formatting results in a file of around 18MB. And we have to copy+paste information from the. But, the Excel file does not do any formatting, such as page numbers, page labels, etc. We have been using a macro-enabled Excel file to compile the manuals. The script will look at a bill of materials, compile the individual documents listed in the bom into one document, and add page numbers to the new document. With open ("Input.pdf", 'rb') as pdf_stream:ī("Output.I am building an automation script to build pdf parts manuals.

PDF compression made easy with 'Aspose.Words for Python via. On the next pass, the sequence of images is compressed and combined to form the content of a new, optimized PDF file. Our product uses adaptive and highly efficient image compression algorithms that allow developers to get compact PDF output while maintaining the optimal quality of the document. During the first pass, all pages of the PDF are converted to image format. PDF compression is performed in two passes. Our product provides Python developers with an integrated API to reduce the size of PDF files. It is a standalone PDF document processing solution for Python that does not require any third party software to be installed. Easily get optimized PDF output ready for printing, archiving or sharing over the network. This Python library provides developers with the ability to quickly and efficiently compress PDF documents programmatically.
