Any file you can print can be converted to a protected PDF to prevent copying or printing. This allows you to add a layer of protection to your Word documents, PowerPoint presentations or other editable filetypes before posting them to iLearn.
Caveat: There are tools available on the internet to override encryption. But this method will suffice for most users without having to purchase a full version of Adobe Acrobat Pro.
Open your file as normal.
Select Print... from the File Menu.
In the lower left corner is a PDF button. Click and select Save as PDF...
The Save dialogue box will open. Type in a name for your document and select a location to save it. Make sure it has the .pdf extension.
At the bottom of the Save dialogue box is a button: Security Options...
Check any options you wish:
Require password to copy text, images or other content
Require password to print document
Type in a password, verify it and click OK.
Then click Save.
Create a protected PDF in Windows
Windows does not have a built in method of creating protected PDFs. A free, third party application PDF Creator will allow you to "print to PDF" and add security options.
