Could you build this?
No Writing an 11MB standalone, offline, cross-platform PDF editor with true WYSIWYG editing, redaction, text reflow, and conversion requires a native C++/Rust PDF parser/rendering engine, as the ISO 32000 PDF spec is notoriously complex and impossible to implement from scratch via vibe coding.
What it would actually take: A lightweight native PDF editor is typically built in C++ or Rust (often with Qt, Skia, or native platform widgets) wrapping or extending low-level libraries like MuPDF, PDFium, or Poppler. The hardest parts involve font embedding/subsetting, accurate text layout engines, incremental document updates according to the ISO 32000 specification, and native OCR integration without pulling in hundreds of megabytes of bloat. This requires deep systems programming and low-level document format expertise.
