When the malicious person clicks on it, they will then find themselves in a crazy position to say the least with fake PDFs which will absolutely not open for them. The idea is that it will eventually lose interest, especially if several fake PDFs are in approximately the same place and will leave you. But the other reason for wanting fake PDFs is very different.

A trick to save some time

Because yes, for some, make fake pdf, it is above all an excuse that will serve to save time. This tip is quite common, whether with your teachers or bosses. We give you a very basic situation. Your boss or professor asks you to submit work by a date. Even though you are there the day before or the same day, your work is far from finished.

You would then like to have an extra 24 hours to be able to finish and get a good grade. So, the trick will be to send a fake PDF and pretend to your interlocutor that the problem comes from their computer.

For this, there is a very simple site called File Destroyer 2.0. This site has a basic interface, but devilishly effective. Here the idea is simple, you enter the type of folder you want, its name and its size.


Then, all you have to do is download your corrupted attachment which will never open. Simply send it by email and wait for the person in front to respond. Once they tell you that the attachment doesn't work, pretend it's a computer problem and send them your finished work.

The limits of the fake PDF technique

On paper, this fake PDF technique is impeccable. Except that in reality, if the person in front has a minimum of knowledge, they risk quickly falling into the water and you then get into trouble.

Indeed, it is for example a technique that we strongly advise you not to use several times. Because inevitably, after a while, the person in front of you will understand this fake PDF ploy. Also there are something that may indicate your cheating to the person in front, it's file size.

In fact, you will never manage in advance to reach the exact weight that you sent to your correspondent.

Therefore, by comparing the two weights it could understand that at a minimum you have made modifications to your file. This is how he understands that even if there was a problem, you saved time.

Therefore, this fake PDF technique, although it is effective from time to time, do not abuse it otherwise the situation will completely turn against you without you expecting it. This is even more true if the person in front of you has already used it themselves.

Protect your PDFs using a code

Okay, now that we have seen the main reason why people make fake PDFs, let's look at the other case which is still much rarer, that of people who do it to protect files.

Admittedly, this fake PDF technique can work, but again, if the person in front of you is at least computer-savvy, it won't take long for them to see that something is wrong.

So she'll often dig a little deeper into the whole thing and that's when she might find out that you actually tried to get her. Except that your files are not protected.

Therefore, in this scenario, what we will advise you is that rather than creating false PDFs, you must simply harden your sensitive files using passwords. It's quite simple and only takes a few minutes.

Here's the procedure to follow:

  • Open the PDF document in AcrobatDC.
  • Go to Files.
  • Choose Protect with a password.

    put password on pdf
    put password on pdf
  • Type the password and validate.

That's it, from now on your PDF files will be secured using a password that only you and the people authorized to open the file will know. You therefore no longer need to make fake PDF.


In summary, making fake PDFs, if it is to protect your computer, is not the best. On the other hand, if it is to scam a file rendering, it can work. Keep in mind, however, that this could prove to be a failure and that you will have to suffer the consequences.
