Why Encrypt your Assignments?
In a digital learning environment, protecting your intellectual work is important. Encrypting your PDFs ensures that only authorized people (like your professor or TA) can view your content.
How to Protect a PDF
- Go to Protect PDF.
- Upload your document.
- Set a strong, memorable password.
- Download the encrypted file.
What happens after protection?
When anyone opens the file, they will be prompted for a password. This works in all major PDF viewers including Chrome, Adobe Acrobat, and Apple Preview.
