Decryption & Document Recovery Architecture
In-Memory Decryption
When you supply the correct password, your browser decrypts the document objects in local RAM, strips the encryption dictionary, and writes a standard unencrypted PDF stream.
Preserving Document Layout
Decryption does not alter page dimensions, vector layers, embedded images, or bookmarks. The output file is a clean, standard PDF that opens without password prompts.
Owner vs User Authentication
If a document has an owner password restricting printing or copying, authenticating with the owner password enables full permission restoration.
