Pdf

This is a comprehensive PDF toolkit that covers the full spectrum from basic operations like merging and splitting to more advanced tasks like table extraction and form filling. It's built around pypdf for manipulation, pdfplumber for pulling structured data from tables, and reportlab for generating PDFs from scratch. The guide includes both Python APIs and command-line tools like qpdf and pdftotext, so you can script complex workflows or just bash out a quick merge. What's actually useful here is the table extraction with pdfplumber, which can dump tabular data straight into pandas DataFrames. The forms.md reference suggests it handles PDF form filling too, which is notoriously annoying to get right.

PDF Processing Guide

Overview

This guide covers essential PDF processing operations using Python libraries and command-line tools. For advanced features, JavaScript libraries, and detailed examples, see reference.md. If you need to fill out a PDF form, read forms.md and follow its instructions.

Quick Start

from pypdf import PdfReader, PdfWriter

# Read a PDF
reader = PdfReader("document.pdf")
print(f"Pages: {len(reader.pages)}")

# Extract text
text = ""
for page in reader.pages:
    text += page.extract_text()

Merge PDFs

from pypdf import PdfWriter, PdfReader

writer = PdfWriter()
for pdf_file in ["doc1.pdf", "doc2.pdf", "doc3.pdf"]:
    reader = PdfReader(pdf_file)
    for page in reader.pages:
        writer.add_page(page)

with open("merged.pdf", "wb") as output:
    writer.write(output)

Split PDF

reader = PdfReader("input.pdf")
for i, page in enumerate(reader.pages):
    writer = PdfWriter()
    writer.add_page(page)
    with open(f"page_{i+1}.pdf", "wb") as output:
        writer.write(output)
