PDF Editor for Mac
A native macOS PDF editor powered by a custom-built Swift PDF engine — no C dependencies, full concurrency support.
Two projects in one: a standalone PDF processing engine (parsing, text extraction, encryption, digital signatures, forms, OCR text writing, PDF/A export) and the macOS editor built on top of it. The engine handles low-level PDF manipulation while the app provides the UI — annotations, inline text editing, watermarks, batch processing, merge/split, and cloud storage integration. The engine is a pure Swift package with zero external dependencies.
