You can then download the password-protected document.
Password-protecting a PDF file is the easiest way to keep it private. It only requires that the user enter a password. This password is used to unlock the PDF file when the recipient opens it. However, this method is not ideal because of its security flaws. Moreover, it can also slow down your computer.
There are various ways to password-protect a PDF file. One option is to use Adobe Acrobat. Once the file has been encrypted, Adobe Acrobat will allow you to share it by email. But this approach will make your laptop heavier and has security flaws. Another option is to use Microsoft Office. Microsoft Office will also allow you to password-protect a PDF file.
If you don’t want to buy Adobe Acrobat to password-protect a PDF, you can use free tools that offer the same functionality. These tools allow you to upload a PDF file, set a password and select an appropriate encryption method. You can then download the password-protected PDF file.
