Technical Specifications
Maximum file size: 50MB. Uses 128-bit AES encryption (PDF 2.0
standard). Compatible with all PDF readers including Adobe Acrobat
Reader, Preview, and web browsers. Password-protected PDFs require the
password to open; forgotten passwords cannot be recovered. All
processing occurs over secure HTTPS connections with TLS encryption.
Files are automatically deleted within 60 minutes.
Privacy & Security
Your PDFs are never stored permanently. Files are automatically
deleted from our servers within 60 minutes of processing. We do not
access, view, or analyze your document content beyond the encryption
process. Your password is never stored or logged — we use it only to
encrypt your file. No personal information is collected or required to
use this tool.
Important: Password Recovery
Once a PDF is password protected, we cannot recover or reset your
password. The encryption is one-way — only the correct password will
open the file. We strongly recommend storing your password in a secure
password manager. Without the password, the PDF cannot be accessed.
