What is SmartDecrypt? SmartDecrypt helps you unlock password-protected PDFs and archives without hunting through notes, messages, or old emails for the right password. Save a pattern once — such as a bank statement or invoice filename format — and SmartDecrypt matches future files automatically and decrypts them instantly, no prompts needed. Available as a universal purchase for both iPhone/iPad and Mac. Buy once, use on all your Apple devices with the same Apple ID.
