A Portable Document Format file is a computer application that equips a user to protect the content of the file.
It is a portable and compatible file format that can be opened on any system.
You can insert as much content as you want as the compression algorithms compress the size of the graphics or other elements of content inserted in a PDF file format.
You can protect the content with the help of passwords.
Not only this, if you have forgot your password or secret character you can easily use advanced computer programs for the purpose of recovering a Portable Document Format file.
There are two ways with which you can encrypt your PDF documents.
A person can select a PDF converter tool in order to encrypt the files.
These are the computer programs that not only help you with the encryption but also with the conversion process.
For instance, a person is preparing an annual report or a project in Word document.
After you are done with your project, you can convert Word to PDF application for perfect presentation.
A Portable Document Format renders a professional presentation to the appearance of the document.
You can set a PDF file with either a user or owner password.
With the former one, a person can disable any facility such as printing or copying the contents of the file.
By using the latter option, an author can set a specific password and only that user who has knowledge of the secret code can access the PDF file.
One can set either 128 bit or 40 bit encryption and the former one is much strong than the latter as it difficult to break.
What happens when you have forgotten the password? It is not an easy task to remember the passwords of different PDF files when you have been often preparing such documents.
A person requires a computer program or a tool in order to open the protected PDF file.
One can create a new one after opening a document and making necessary updates.
The advanced programs help you to set and recover the password with convenience.
