The PDF engine behind over 50 million monthly downloads, powering AI pipelines worldwide.
PyMuPDF is a high-performance Python library for data extraction, analysis, conversion, rendering and manipulation of PDF (and other) documents. Built on top of MuPDF — a lightweight, fast C engine — PyMuPDF gives you precise, low-level control over documents alongside high-level convenience APIs. No mandatory external dependencies.
- Fast — powered by MuPDF, a best-in-class C rendering engine
- Accurate — pixel-perfect text extraction with font, color, and position metadata
- Versatile — read, write, annotate, redact, merge, split, and convert documents
- LLM-ready — native Markdown output via PyMuPDF4LLM for RAG and AI pipelines
- No mandatory dependencies —
pip install pymupdfand you're done
pip install pymupdfWheels are available for Windows, macOS, and Linux on Python 3.10–3.14. If no pre-built wheel exists for your platform, pip will compile from source (requires a C/C++ toolchain).

PyMuPDF is built on MuPDF — one of the fastest PDF rendering engines available. Typical benchmarks against pure-Python PDF libraries show 10–50× speed improvements for text extraction and 100× or more for page rendering, with a minimal memory footprint.
For AI workloads, PyMuPDF4LLM processes documents without a GPU, cutting infrastructure costs significantly compared to vision-based LLM approaches.

doc.save("watermarked.pdf")PyMuPDF can be extended with PyMuPDF Pro. This adds a conversion layer that handles Microsoft and Korean Office formats natively — no Office installation, no COM interop, no LibreOffice subprocess.
Once unlocked, pymupdf.open() accepts Office files exactly like PDFs:
importpymupdf.propymupdf.pro.unlock("YOUR-LICENSE-KEY")
# Works identically regardless of formatforfmtin ["contract.docx", "data.xlsx", "deck.pptx", "report.hwpx"]:
doc=pymupdf.open(fmt)

What you can do with Office documents:
- Extract text and images page-by-page
- Convert to PDF with
doc.convert_to_pdf() - Rasterise pages to PNG/JPEG for visual inspection
- Feed directly into PyMuPDF4LLM for AI-ready output
When pymupdf.pro.unlock() is called without a key, the following restrictions apply:
| Restriction | Detail |
|---|---|
| Page limit | Only the first 3 pages of any document are accessible |
| Time limit | Evaluation period — functionality expires after a set duration |
All other Pro features work normally within these constraints, making it straightforward to prototype before purchasing a license.
Yes, absolutely — and this is one of PyMuPDF's most significant advantages.
PyMuPDF runs entirely locally. It is a native Python library built on top of the MuPDF C engine. When you call pymupdf.open(), page.get_text(), page.find_tables(), or any other method, everything executes in-process on your own machine. No data is transmitted anywhere.
There are no telemetry calls, no licence validation callbacks, no cloud dependencies of any kind in the open-source AGPL build or the commercial build. Once the package is installed, it works fully air-gapped.
This makes PyMuPDF well-suited for:
- Regulated industries — healthcare (HIPAA), finance, legal, government, where documents cannot leave a controlled environment
- On-premise deployments — servers with no outbound internet access
- Air-gapped systems — classified or sensitive environments
- Self-hosted RAG pipelines — processing confidential documents locally before feeding an on-premise LLM
- Saving on token costs for document pre-processing before sending data to your LLM
The only thing you need an internet connection for is the initial pip install. After that, the package and all its capabilities are entirely self-contained.
Use import pymupdf. The fitz name is a legacy alias that still works as of v1.24.0+, but import pymupdf is the recommended and future-proof approach. The two are interchangeable in existing code:
importpymupdf# recommended# import fitz # legacy alias — still works but avoid for new codeYes — PyMuPDF has solid CJK support
Let PyMuPDF4LLM do everything (recommended for RAG).
PyMuPDF4LLM is a high-level wrapper that outputs standard text and table content together in an integrated Markdown-formatted string across all document pages PyMuPDF — tables are detected, converted to GitHub-compatible Markdown, and interleaved with surrounding text in the correct reading order. This is the best starting point for feeding an LLM or building a RAG pipeline.
importpymupdf4llmmd=pymupdf4llm.to_markdown("report.pdf")
print(md)
# Tables appear as Markdown | col1 | col2 | ... inline with the textThis usually means the PDF uses custom font encodings without a proper character map (CMAP). The font's glyphs are present but cannot be mapped back to Unicode. In these cases:
- Use OCR as a fallback (
page.get_textpage_ocr()) - Consider that scanned PDFs will always need OCR — text extraction on scans returns nothing
Pass a clip rectangle to get_text():
importpymupdfdoc=pymupdf.open("input.pdf")
page=doc[0]
# Define the area you want (x0, y0, x1, y1) in pointsclip=pymupdf.Rect(50, 100, 400, 300)
text=page.get_text("text", clip=clip)importpymupdfdoc=pymupdf.open("input.pdf")
page=doc[0]
# Returns a list of Rect objects surrounding each matchlocations=page.search_for("invoice number")
forrectinlocations:
print(rect) # e.g. Rect(72.0, 120.5, 210.0, 134.0)Charts and diagrams created by tools like matplotlib, Excel, or R are typically rendered as vector graphics (PDF drawing commands), not raster images. get_images only lists embedded raster image objects and will not detect vector graphics. To capture these, rasterise the entire page with page.get_pixmap().
PyMuPDF uses MuPDF's built-in Tesseract-based OCR support, so there is no Python-level pytesseract dependency. However, PyMuPDF still needs access to the Tesseract language data files (tessdata), and automatic tessdata discovery may invoke the tesseract executable (for example, to list available languages) if you do not explicitly provide a tessdata path. In practice, the recommended setup is to either install Tesseract so discovery works automatically, or configure the tessdata location yourself via the tessdata parameter or the TESSDATA_PREFIX environment variable. Over 100 languages are supported.
importpymupdfdoc=pymupdf.open("scanned.pdf")
page=doc[0]
# Get a text page using OCRtp=page.get_textpage_ocr(language="eng")
text=page.get_text(textpage=tp)
print(text)importpymupdfpix=pymupdf.Pixmap("image.png")

# Use quads=True for accurate highlights on non-horizontal textquads=page.search_for("important term", quads=True)
page.add_highlight_annot(quads)
doc.save("highlighted.pdf")PyMuPDF supports all standard PDF text markers: highlight, underline, strikeout, and squiggly.
Redaction is a deliberate two-step process so you can review before committing:
importpymupdfdoc=pymupdf.open("input.pdf")
page=doc[0]
# Step 1: Mark the area(s) to redactrect=page.search_for("confidential")[0]
page.add_redact_annot(rect, fill=(1, 1, 1)) # white fill# Step 2: Apply — permanently removes the underlying contentpage.apply_redactions()
doc.save("redacted.pdf")After apply_redactions(), the original content is gone. It cannot be recovered from the saved file.
importpymupdfdoc=pymupdf.open("form.pdf")
page=doc[0]
forfieldinpage.widgets():
print(f"{field.field_name}: {field.field_value}")importpymupdfdoc=pymupdf.open("form.pdf")
page=doc[0]
forfieldinpage.widgets():
iffield.field_name=="First Name":
field.field_value="Ada"field.update()
doc.save("filled_form.pdf")No. PyMuPDF does not support multithreaded use, even with Python's newer free-threading mode. The underlying MuPDF library only provides partial thread safety, and a fully thread-safe PyMuPDF implementation would still impose a single-threaded overhead — negating the benefit.
Use multiprocessing instead. Each process opens the file independently and works on its own page range:
frommultiprocessingimportPoolimportpymupdfdefprocess_pages(args):
path, start, end=argsdoc=pymupdf.open(path) # each process opens its own handleresults= []
foriinrange(start, end):
results.append(doc[i].get_text())
returnresultswithPool(4) aspool:
chunks= [("input.pdf", 0, 25), ("input.pdf", 25, 50), ...]
all_results=pool.map(process_pages, chunks)Reuse a TextPage object. Creating a TextPage is the expensive part — once created, switching between extraction formats is cheap:
importpymupdfpage=doc[0]
tp=page.get_textpage() # create oncetext=page.get_text("text", textpage=tp)
words=page.get_text("words", textpage=tp)
data=page.get_text("dict", textpage=tp)This can reduce execution time by 50–95% for repeated extractions on the same page.
