How ZIP Password Recovery Works
Upload ZIP Archive
Upload your password-protected ZIP, 7z, or SFX file. We automatically detect the encryption type and run a free initial check against common passwords.
Server-Powered Recovery
Our powerful servers process up to 200 million password combinations per second using dictionary attacks, brute force, hybrid methods, and smart pattern matching.
Get Your Password
Once found, you receive the password via email. You only pay if we find your password. Use it to extract your files with any ZIP utility. Simple PINs (up to 4 digits) and top 10K common passwords are FREE if found during Fast Check.
ZIP Encryption Types
PKZIP (ZipCrypto)
- Legacy encryption
- Most common type
- Very high success rate
WinZip AES-256
- Modern encryption
- AES-256 + PBKDF2
- Depends on complexity
7-Zip (AES-256)
- Strongest archive encryption
- AES-256 + SHA-256
- Hints recommended
Common Scenarios
Forgetting a ZIP password is more common than you think. Here are the situations we see every day:
PKZIP vs AES Encryption
PKZIP / ZipCrypto (Legacy)
Older ZIP files and files created with Windows built-in compression use ZipCrypto (also called PKZIP encryption). This is a legacy algorithm with known cryptographic weaknesses, allowing our servers to test passwords at extremely high speeds. Most PKZIP archives are recovered very quickly.
WinZip AES-256 / 7-Zip AES-256 (Modern)
Files created with WinZip's "AES encryption" option or 7-Zip use AES-256, a much stronger algorithm. Recovery is significantly slower due to the encryption strength. Success depends on password complexity — providing hints with our Deep Recovery + AI plan significantly improves your chances.
Not sure which encryption your file uses? Just upload it — we detect the type automatically and tell you before you pay.
