Our advanced recovery method includes an exhaustive search through a massive database containing over 20 billion known passwords. Beyond just database checks, we utilize sophisticated extended techniques and combined attacks, significantly increasing your chances of success. Depending on the complexity of the file encryption and the current workload on our servers, this process can take up to 24 hours. With this advanced method, the success rate jumps to around 61%.

| 7z Password Recovery (*.7z) | |||||
|---|---|---|---|---|---|
| Recovery Type | Success rate | Estimated Time | Price | ||
| Weak Password Recovery | ≈ 22% | Within a few minutes | Free | Start | |
| Strong Password Recovery | ≈ 61% | Up to 24 hours | $49.00 * | Start | |
| Brute Force ** | 100% *** | Time depends on mask complexity | On Request | Custom Request | |
* You only pay after the password is successfully recovered.
** We search all possible password combinations based on the specified mask, which must include the password’s structure — like maximum length and character set — because without it, brute-forcing a 10-character password blindly would take thousands of years (over 67 quintillion combinations); you can estimate this using our Brute Force calculator.
*** A 100% success rate is guaranteed only if the mask you provide is accurate. If the mask parameters — including character set and maximum length — are incorrect, recovery will fail. Please use mask-based recovery only if you're confident about the exact structure of the password.

How to Unlock a Password-Protected 7z File?
If you already have the password, removing it is straightforward. The 7z program itself does not directly remove the password from an encrypted archive. However, you can easily extract the archive contents to a new folder using your known password and then re-create a fresh 7z archive without setting any password protection.
If you do not know your password, the first step is recovery. Upload your file now, and let our powerful recovery algorithms handle the rest.
