Choose the most appropriate attack method based on what you remember about the password.
Start the recovery process and wait while our tool finds your password.
Choose the right approach based on what you know about the password
Systematically checks all possible password combinations until the correct one is found. This method is comprehensive but can be time-consuming for longer passwords.
Tests passwords from a predefined list of common passwords and words. This method is much faster than brute force when the password is a common word or phrase.
Uses information you know about the password structure (like length, character types, or certain known characters) to reduce the search space dramatically.
Combines dictionary words with brute force techniques, adding numbers or symbols to dictionary words. This catches common password patterns like "password123".

Absolutely. Our tool processes files entirely in your browser - we never upload your files to our servers. Your files remain private and secure on your own device.
We support ZIP 2.0 legacy encryption (most common), AES-128, and AES-256 encryption used by WinZIP, WinRAR, and 7-Zip. Note that stronger encryption takes longer to crack.
Recovery time depends on password complexity, attack method, and your device's processing power. Simple passwords may take seconds, while complex ones could take hours or days.
Yes, our tool works with ZIP files created by any version of PKZIP, WinZIP, or other ZIP utilities, including very old files from the 1990s.
