Hello, I purchased the subscription yesterday, my main goal is to protect the PDF file from being copied or converted back to PPP. so to protect it.

I encrypted my file wit password and closed all options to copy/ edit/ print to be only with password.

I tried to copy any text and it was not allowed, that's perfect.

 

But I tried myself external website to convert the file from PDF into PPP and it is successfully converted the protected file from PDF to PPP. so this goal is not acheived. I see other people when secure their files, all external websites can't cover it to PPP and even te text is being like special chacters. how I can do it? 

thanks too much in advance

    @Hesham_A.3751 those online tools have no security whatsoever. They strip it out like no tomorrow. My sister will always ask me to password protect or encrypt the PDF to send to someone, and I always say, people can use an online tool, and it will ignore th security feature set my Acrobat, and strip it out, and download a fresh PDF with no security. If you truly want to prevent conversion, and maybe make the appear as "special characters" or unreadable gibberish to converters, you need to flatten the document - File - Print - Select PDF - Print As Image (if by chance it is grey out, make sure grayscale is not selected!)

    You can still put a password on it for security, and sure, someone can use a online tool and converts it, the PPT should just contain static images of your slides that cannot be edited as text.

    There's no real way of doing it that's 100% secure. It's just a question of how much time and money you want to spend on it, but someone willing enough will always find a way around it.
