PyMuPDF is an efficient library tailored for Python that facilitates the reading, extraction, and manipulation of PDF files with remarkable accuracy. It allows developers to efficiently access various elements within PDF documents, such as text, images, fonts, annotations, metadata, and their structural layouts, enabling a wide range of operations, including content extraction, object editing, page rendering, text searching, and modifications of page content. Additionally, users can manipulate components of the PDF, including links and annotations, while performing advanced tasks like splitting, merging, inserting, or removing pages, as well as drawing and filling shapes and managing color spaces. This library is designed to be both lightweight and powerful, ensuring minimal memory usage while optimizing performance. Furthermore, PyMuPDF Pro extends the core capabilities, providing features for reading and writing Microsoft Office-format files and enhanced integration options for Large Language Model (LLM) workflows and Retrieval Augmented Generation (RAG) techniques. As a result, developers can seamlessly work across different document types, making PyMuPDF an invaluable tool for a wide range of applications.
