Maximum upload file size: 100MB
You can try a free check for weak passwords: it is successful in about 22% of all cases, and it takes only one or two minutes to see the result.
If the password is not recovered with a free check, you will be offered a paid option to try a 20+ billion passwords database check. This is our "nuclear weapon," and a search through such a huge database may take up to 24 hours, depending on the file version and our computing cluster workload. Your chances to recover the password successfully are about 61% in this case.
Here is more information about the password recovery chances.
If you already know the password to the archive, it is simple. Actually, you can't remove password protection from an already protected 7z archive with 7z program. But you can extract archive to a folder, and then add all files to a new 7z archive without password.
If you do not know the password, you need to recover it first. Upload the file to our website and wait until we complete the work.

* You pay only for a successful password recovery, after the job is done.
** We systematically search through all possible password variants according to the specified mask. To build the proper mask, we need all the information about the password structure, including its maximum length and the character set. A blind search through all possible password variants is useless. Just imagine, finding a 10-character password blindly, even with our high-performance cluster, would take thousands of years because there are more than 67 quintillion (67 * 1018) possible variants. You can calculate the number of password options and the approximate search time online with our Brute Force calculator.
*** 100% successful password recovery is guaranteed only if you have specified the correct mask. We will never recover the password successfully if its mask parameters, including the character set and length, are incorrect. So, please, order a mask password recovery only if you know for sure the password structure: its maximum length and the character set.
