Could you build this?
Partial A basic PDF viewer and editor is buildable, but 150+ tools including true redaction, digital signing, form handling and conversions is a large, edge-case-heavy effort that vibe coding alone won't cover.
What it would actually take: Build on existing engines such as PDFium, MuPDF or pdf.js and libraries like pypdf or PDFBox for parsing and writing. The hard parts are correct PDF object manipulation, true content removal on redaction, certificate-based digital signatures and faithful Office conversions. This needs deep knowledge of the PDF specification and sustained, mature engineering over years.
