Protect PDF, add a password
Add a password to a PDF and restrict printing or copying, with real AES-256 encryption applied to the file. This tool runs on our server, not in your browser.
Drop your files
Server-side processing (necessary for this tool). File deleted right after we send back the result.
Why this tool needs a server (and how we handle it)
- This tool needs a binary that doesn't run in browsers (Ghostscript, qpdf, LibreOffice, or Tesseract).
- Your file is processed in an isolated tmpdir per request, on our own server: a VPS in Mumbai, India.
- We delete the tmpdir immediately after the response is sent. A cron backstop clears anything left within an hour (for example after a crash).
- The disk is not encrypted at rest; the file only exists on it for the seconds it takes to process, then is deleted.
- No logging of file contents. No human review. Never used for training, never shared, never kept.
- Sent over HTTPS (TLS), with HSTS preload and a strict CSP enforced.
