PyMuPDF: High-Performance PDF Processing for Python

Fri, 01 May 2026 00:00:00 +0000

When you need raw speed for PDF processing, PyMuPDF is the performance leader among Python PDF libraries. Built as a Python binding to the C-based MuPDF library from Artifex, PyMuPDF combines Python’s ease of use with C-level performance for rendering, extracting, and manipulating PDF documents.

PyMuPDF processes PDFs 10-100x faster than pure Python alternatives. It renders pages to images in milliseconds, extracts text with precise positioning, manages annotations, and handles forms. Beyond PDF, it also supports XPS, EPUB, MOBI, FB2, and common image formats, making it a versatile document processing engine.
