How to Batch Decrypt Multiple Password-Protected Files at Once

SmartDecrypt PDF ZIP CBZ decrypts multiple password-protected PDF, CBZ, and ZIP files in a single operation on iPhone, iPad, and Mac. Select any number of protected archives, apply one password or a saved password profile, and the app processes every file on-device — no uploads, no per-file waiting. After decryption, open your CBZ comics in BiblioFuse for the best reading experience on iPhone. SmartDecrypt's batch decrypt is the fastest way to clear an entire collection of password-protected files.

The Problem with One-File-at-a-Time Decryption

You have 50 bank statements, all password-protected PDFs from the same institution. Or a folder of 30 fan-translated CBZ comics from the same publisher, all using the same archive password. Opening each file individually — import, enter password, decrypt, save — takes minutes per file. For large collections, that adds up to hours of repetitive work.

Most decryption tools on iPhone process files one at a time. They have no concept of batch operations or reusable password profiles. You end up copying and pasting the same password dozens of times.

SmartDecrypt PDF ZIP CBZ solves this with two features working together: batch decrypt and password profiles. Select all files at once, apply the profile, and tap once.

SmartDecrypt handles this entirely on-device — no cloud service, no per-file wait, no upload.

How Batch Decrypt Works in SmartDecrypt

Step 1: Create a Password Profile (Recommended)

Before batch decrypting, save a password profile for the collection. In SmartDecrypt, go to Profiles, tap Add Profile, enter a name (for example, "Bank Statements 2025" or "Publisher X Comics"), and enter the password. The profile is saved securely on your device and never synced to any cloud.

Step 2: Import Multiple Files

Open SmartDecrypt and tap Import. Select multiple files from the Files browser. You can also multi-select files in the iOS Files app and share them all to SmartDecrypt at once using the share sheet.

Step 3: Apply the Password

With all files loaded, either type the password once or select the saved profile. The same password applies to every file in the batch.

Step 4: Tap Decrypt

SmartDecrypt processes every file in sequence. For typical archives, each file completes in under a second on a modern iPhone. A batch of 50 bank statements finishes in under a minute.

Step 5: Access Your Decrypted Files

All decrypted files are saved to your Files app. Each unlocked file keeps its original filename. Open CBZ files in BiblioFuse, import PDFs into a document app, or share them as needed.

When to Use Batch Decrypt

Annual Financial Documents

Banks and institutions send statements, tax forms, and account summaries as password-protected PDFs. Accumulating a year of monthly statements means 12 identical decryption operations. Batch decrypt handles all 12 in a single tap.

Comic Library Imports

If you're building a digital comic library on iPhone using BiblioFuse, and your comics arrived as password-protected CBZ archives, batch decrypt is the fastest path. Import all archives at once, decrypt in one operation, and your entire collection is ready to organize in BiblioFuse.

ZIP Backups and Document Collections

ZIP archives from app exports, email archives, or personal backups often carry password protection. Batch decrypt removes the passwords from an entire folder's worth of files at once, making the contents available to any app.

Password Profiles: Save Once, Reuse Forever

The password profile store is the feature that makes batch decryption practical for real-world use. Most collections involve the same password applied to many files: a bank always uses the same format, a publisher uses one archive password for all their releases, a fan group posts one password per series.

Profiles are named, stored securely on-device, and never synced to any cloud service. You can create as many profiles as you have collections, and delete them when they're no longer needed. There is no limit on the number of profiles you can save.

Does Batch Decrypt Work on Mac Too?

Yes. SmartDecrypt PDF ZIP CBZ is a universal app: the same purchase covers iPhone, iPad, and Mac. The Mac version handles larger files faster and supports drag-and-drop import. You can select hundreds of files at once in Finder and drop them into SmartDecrypt for a single-pass batch decrypt.

The Mac Share Extension also supports multiple files: select a batch in Finder, right-click, choose Share → SmartDecrypt, and batch decrypt in one step.

What is a password profile in SmartDecrypt? A password profile is a saved name-and-password pair stored securely on your device.
