How Client-Side AES-128 PDF Encryption Protects You
Standard web compressors and cloud document utilities ask you to enter confidential passwords into remote HTML forms. This means the service provider receives both your unencrypted document and your password on their server disks, creating compliance liabilities for legal teams and accounting departments.
DocSnap implements AES-128 bit symmetric encryption inside your browser memory using WebAssembly. The cipher engine recalculates file trailers and encrypts content streams using native client hardware. The encrypted PDF cannot be opened in Adobe Acrobat, Apple Preview, or Chrome without entering the exact user password you specified.
Frequently Asked Questions
Is my password or document sent to an external server?
Never. Encryption key derivation and AES-128 object stream ciphering execute strictly inside your computer's local RAM. Your document and password never cross the internet.
What happens if I forget the password I set?
Because DocSnap maintains a zero-knowledge, zero-upload architecture, we do not store password databases. Keep a backup copy of your password in a trusted password manager.
