PDF Toolkit is designed with privacy as the core architecture principle:
- 100% Client-Side: All document processing (merging, splitting, OCR, signing, redact, compressing, etc.) runs entirely inside your browser using WebAssembly and Web Workers.
- Zero Network Transmission: No documents, files, form values, or metadata are ever transmitted, logged, or uploaded to any remote server or third-party service.
- Offline Capable: The application operates identically with network access disabled or directly from local storage (
file://).
If you discover a security vulnerability, issue, or unintended network leak within this project, please report it responsibly:
- GitHub Security Advisory: You can submit a private vulnerability report via GitHub Security Advisories.
- Direct Contact: You can also contact the maintainer directly via WhatsApp at +62 857-7777-5477.
Please provide:
- A description of the issue.
- Steps or a proof-of-concept to reproduce the behavior.
- Browser name and version used.
We will review reports promptly and take necessary corrective actions.
