PyMuPDF

PyMuPDF is a comprehensive PDF manipulation library and document analysis tool. It serves as a text extraction tool, OCR engine, and image converter, providing a programmatic interface to edit, merge, split, and optimize PDF and Office documents.

The project distinguishes itself through high-performance capabilities, including the use of C-bindings for low-level manipulation and parallelized page processing to accelerate workloads. It provides specialized conversion paths, such as transforming PDF content into Markdown for retrieval-augmented generation and large language model pipelines.

Its broader capability surface covers optical character recognition for creating searchable text layers, detailed data extraction of tables and key-value pairs, and security operations including AES/RC4 encryption and permanent content redaction. The library also handles complex document geometry, layout analysis, and the generation of PDFs from HTML and CSS.

The library supports multi-format document loading for PDF, EPUB, MOBI, SVG, and Office files, with the ability to process files via memory streams.
