This is your Swiss Army knife for PDF work. You get text extraction with pdfplumber (including tables), basic operations like merging and splitting with pypdf, and PDF creation from scratch using reportlab. The guide covers both Python libraries and command-line tools like qpdf, plus it includes OCR for scanned documents and form filling instructions in a separate doc. The table extraction to pandas DataFrames is especially handy. It's comprehensive enough that you won't need to hunt down other references for most PDF tasks, whether you're processing invoices at scale or just need to split a document.
