Double unlocking of protected PDF files

Using our module, you can very easily unlock protected PDF files, enabling you to override the encryption and password for the PDF document.

Decryption

Decryption

First of all, the PDF Smart tool enables you to unlock a PDF file by overriding the encryption algorithm.
To make this happen, our PDF unlocking protocols analyse the encryption of the document to remove it, enabling you to view the protected file.
However, with strong encryption (AES 256-bit for example), the password may still be required to unlock the document.

Any password

Any password

In the event of a poor encryption protocol, our online module is capable of overcoming any password for a PDF file, even the most complex (random alphanumeric sequence, special characters, etc.).
By unlocking the PDF file, you can then view it more easily, especially if you have forgotten the password.

Great security

Great security

When your PDF document has been unlocked, PDF Smart does not view the document and has no rights over it.
We also encrypt your data using effective protocols in order to guarantee your privacy.
Finally, the unlocked PDF document is deleted immediately from our servers.
That way, you can be sure that no one else can view the document.
