## What is SmartDecrypt PDF ZIP?

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 can match future files automatically. Passwords with Chinese, Japanese, and Korean characters are now fully supported. On iPhone and iPad, open files from the app or send them through the iOS Share Sheet from Files, Mail, or other apps.

Features:
- Unlock password-protected PDF files.
- Extract ZIP and 7z archives.
- Save password patterns for recurring files.
- Share files directly to SmartDecrypt from iOS.
- Supports UTF-8 passwords including CJK characters.
- Process one file at a time for free.
- Upgrade once to unlock batch file loading and automatic password cycling.
- Keep passwords in the system Keychain.
- Interface available in 11 languages.

SmartDecrypt is designed for files you already have permission to access. It does not bypass unknown passwords.

SmartDecrypt Pro is a one-time universal purchase. Buy once and unlock Pro on both iOS and macOS with the same Apple ID.
