## What it is
PDFPatcher is a free Windows PDF toolbox built on .NET with iText and MuPDF, offering bookmark editing, page cropping/rotation, merging and splitting, image extraction, font replacement, OCR, and a document structure inspector. It is a desktop GUI application released under AGPL with an additional 'conscience license' asking users to do good deeds.

## Use cases
- edit pdf bookmarks in bulk
- merge multiple pdfs with bookmarks
- split a pdf and keep the table of contents
- remove copy and print restrictions from a pdf
- extract images from a pdf losslessly
- convert pdf pages to images
- ocr a scanned pdf and turn its table of contents into bookmarks
- inspect and edit the internal structure of a pdf

## When to choose
- you need a free Windows GUI tool for heavy PDF bookmark editing or batch restructuring
- you want to merge/split PDFs while preserving or regenerating bookmarks
- you need to inspect or tweak low-level PDF document structure
- you work with scanned Chinese books and need right-to-left/vertical reading plus OCR-generated bookmarks

## When to avoid
- you need a library to embed in your own code (it is an end-user application, and its extra 'conscience license' adds obligations beyond AGPL)
- you need cross-platform or Linux/macOS support
- you only need simple viewing or lightweight annotation
- you require a permissively licensed dependency for commercial products
