Handling large files in Python can indeed present challenges, particularly when it involves merging multiple PDFs into a single PDF document. As PDF files can contain complex structures and graphics, processing large PDFs can be resource-intensive and time-consuming. This is especially true when dealing with a significant number of PDF files to merge, as each file needs to be read, processed, and combined into the final output.

The PDF.co Web API’s smooth integration with Python makes it an ideal choice for developers seeking an efficient solution to merge large PDFs. By utilizing Python’s capabilities and leveraging the PDF.co API, developers can simplify the merging process, reducing complexities and enhancing overall performance.
