PDF Password Recover was available as a giveaway on May 9, 2017!
We all had such situations when we had to deal with the password-protected PDF files which are of the great importance. Sometime we may forget the password of the PDF files. At this time, we need an efficient and neat software solution designed to remove or recover the password restrictions from protected PDF files. PDF Password Recover is the one that can instantly recover the password locking the documents.

According to the screenshots, it supports only English letters.
This is a very big minus. The World is full of languages, on which passwords can be typed. For example, from German: ü ö ä, in Spanish there is the letter Ñ, Greek, Turkish: Ç ç Ğ ğ Ö ö Ş ş.
In the given case, I exclude the Russian language (it does not count).

Such paid programs should also be online.
Many do not is no possibility to buy a very powerful computer, there is no possibility to wait a whole month (after all, a person does not remember in which language he wrote the password in his native language or in English).

I have used PDFKey Pro for five years. It has never failed to unlock a password-protected pdf file, leaving the original file intact and producing an _unlocked.pdf copy. For me it has been worth its $25 price.

I did protect a PDF:

To find a user password it took 1 minute:

The owner password will take much longer.
The the folder came a new file PdfPasswordStorage.txt with the found passwords

This is just a glorified brute force password cracker. The limitations are your machine. The more complex the password, the longer it will take, including YEARS.

Why TWO buttons at the bottom of the user interface that pop ups [ Start decryption process ]?
Fist button says [ Remove PDF ] ( does this really just take a highlighted PDF file out of the list above ? )
The second says [ Decrypt ]
Also, rather than 'decrypt', please change to 'find password' or 'remove password'.
So, does this save a password-free file, or just tell you the password for you to try?
Then change to [ Find password(s) ].
Thanks.

I ran the program on a pdf, the password I know is 8 capital letters, after 3 hours nothing, I turned it off

George James Ducas, theoretically, this application is capable of calculating the only and correct password. The most important thing I should boost is the speed of calculation.

support@pdfpasswordrecover.com, I am running a new computer with i7 and 64 bit, you are right, needs a faster calculating approach, perhaps running several sequences simultaneously? i wish i could help, but it would help to be faster

Installed in XP but refuses to run.

XP-Man, Sorry for that. This application requires .Net Framework 4.0 or above right now. We will release a new version which supports Win XP soon. We will inform you if you are kind to leave your email address for us.

If your password is one character, then there are 26 possible combinations. If your password is two characters, then there are 26x26 combinations - 676. This goes up exponentially, so for a ten character password, thats 26x26x26x26x26x26x26x26x26x26... 141,167,095,653,376 combinations. Yes, its going to take a while to test all those. Thats assuming you use just upper or lower case. If you used both, then its 52x52x52x52.... etc. With 15 'additional' symbols (£$%&, etc) thats 67x67x67x67x67.... etc. 1.822e+18 - so 1 with 18 zeroes. Thats gonna take a while.

Chris Locke (CS Computer Services), Correct. This application will try all combinations of passwords and get the correct one.

But can you resume from a point? If the program has been running for 3 weeks, then Windows 10 decides to reboot to install necessary updates, would you have to start at the beginning? That would be a pain...

Unless your user password is 5 characters or less and has no special characters, brute force recovery will take forever on a typical user machine.
Owner password defeat is quite simple, as it doesn't even require guessing since the password mechanism is flawed, it is easily broken.

Downloaded and tried to install twice and both times got the error message: "error reading setup initialzation file"
