I built this because I didn't want to upload contracts to iLovePDF to merge or redact them. Everything runs client-side: edit, sign, merge, split, compress, OCR (Tesseract), redact, PDF to Word. There's no backend, and the CSP only allows the page's own origin. Redaction re-renders pages so the text is actually gone. There's also a Docker image and an offline Windows app.

Feedback welcome, especially on redaction edge cases.
