Files are encrypted directly inside your browser. No data is sent to our servers, ensuring complete privacy.
How Client-Side Password-Protected ZIP Creation Works
Archive and encrypt batches of photos, PDFs, and documents directly in browser memory:
| Encryption Method | Cipher Strength | Native OS Support | Best Use Case |
|---|---|---|---|
| ZipCrypto (Traditional) | Standard | ✓ Windows Explorer & macOS Finder | General file sharing without third-party software |
| AES-256 (WinZip / 7-Zip) | Military-Grade (256-bit) | Requires 7-Zip, WinRAR, or modern unarchivers | Confidential financial, medical, and legal file archives |
Frequently Asked Questions
Everything you need to know about creating secure ZIP archives in your browser.
Can I extract the created ZIP on Windows and Mac without extra software?
Yes. If you choose the default "ZipCrypto" mode, Windows Explorer and macOS Finder can open and extract your password-protected ZIP archive natively without installing any software.
What is the advantage of AES-256 encryption?
AES-256 provides military-grade cryptographic protection against brute-force attacks. It is ideal for storing sensitive corporate documents or personal ID scans.
Are my archive files uploaded to any server?
No. All file compression and encryption execute 100% locally in your browser memory using zip.js and WebAssembly. Your files never leave your device.
