## What it is
pypdf is a free, open-source, pure-Python library for manipulating PDF files. It supports splitting, merging, cropping, and transforming pages, as well as extracting text and metadata, adding annotations, watermarks, and encryption.

## Use cases
- merge multiple pdf files into one
- split a pdf into separate pages
- extract text from a pdf in python
- add a password to a pdf
- crop and rotate pdf pages
- read pdf metadata and annotations
- add a watermark to a pdf

## When to choose
- you need to manipulate PDFs programmatically in Python without external dependencies
- you want to merge, split, or transform PDF pages
- you need to extract text or metadata from PDFs
- you want to encrypt, decrypt, or annotate PDFs

## When to avoid
- you need to render PDFs visually or create complex PDF layouts from scratch
- you need a command-line tool (see pdfly instead)
- you need high-fidelity OCR of scanned documents

## Facets
- artifact type: library
- maturity: active
- function: pdf, parser, ocr
- domain: pdf, files, developer-tools
- platform: python, cross-platform
- tags: pdf-manipulation, pdf-parsing, text-extraction, encryption, merging, splitting, pure-python
