PDF is the universal document format. It is also one of the most annoying formats to work with programmatically. This skill handles the full range of PDF tasks — reading, creating, editing, merging, splitting, and extracting — using the right tool for each job.

| Extract text (digital PDF) | pdfplumber or pdftotext |
| Extract tables | pdfplumber |
| Create PDF from content | reportlab |
| Merge / split / rotate | pypdf or qpdf |
| Fill PDF forms | pypdf or pdf-lib (JS) |

| Password protect / decrypt | pypdf or qpdf |
| Extract images | pdfimages (poppler) |
pypdf,pdfplumber, andreportlabare typically pre-installed. Import directly. Only runpip installif an import fails.
# pdfplumber — preserves layout better than pypdf
import pdfplumber
with pdfplumber.open("document.pdf") as pdf:
print(f"Pages: {len(pdf.pages)}")
for i, page in enumerate(pdf.pages, 1):
text = page.extract_text()
if text:
print(f"\n--- Page {i} ---")
print(text)
# Command line — fastest for quick extraction
pdftotext document.pdf output.txt # basic
pdftotext -layout document.pdf output.txt # preserve column layout
