Pypdf
Overview
PyPDF is a pure-Python library for working with PDF files. This skill covers comprehensive patterns for PDF manipulation including:
- PDF merging - Combine multiple PDFs into one document
- PDF splitting - Extract specific pages or split into multiple files
- Page rotation - Rotate pages by 90, 180, or 270 degrees
- Watermarking - Add text or image watermarks to pages
- Text extraction - Extract text content from PDF pages
- Metadata handling - Read and modify PDF metadata
- Form filling - Fill PDF form fields programmatically
- Encryption/Decryption - Secure PDFs with passwords
When to Use This Skill
USE when:
- Merging multiple PDF files into a single document
- Splitting large PDFs into smaller files
- Extracting specific pages from PDFs
- Adding watermarks or stamps to documents
- Extracting text content for analysis
- Reading or modifying PDF metadata
- Filling PDF forms programmatically
- Encrypting or decrypting PDF files
- Adding page numbers or headers/footers
- Rotating or reordering pages
- Automating PDF workflows in pipelines
DON'T USE when:
- Creating PDFs from scratch (use reportlab or weasyprint)
- Need advanced text layout control (use reportlab)
- Converting other formats to PDF (use dedicated converters)
- Need OCR for scanned documents (use pytesseract + pdf2image)
- Working with complex form creation (use reportlab)
- Need to edit existing text content (limited support)
Prerequisites
Installation
