How to password protect PDF

1Choose a PDF for password protection

Choose file: select the confidential PDF file you wish to protect and drag-and-drop the PDF into the protect a PDF converter box. You can also upload or open the PDF document directly from your computer or using a cloud storage service such as Google Drive or Dropbox. Whichever you choose, encrypt and protect PDF with password security in just a few clicks!

2Select a password

Write out or encrypt your PDF file: choose the password you wish to use to protect your file. Enter the password once more to confirm the encrypt password for your PDF. You should be certain that you will remember this encrypt password, or be sure to save the password in a secure and safe place, before you enter and confirm the password for your PDF file. Similar to Adobe Acrobat, we don’t force you to use any specific encrypt or format for the password you will be adding to your PDF, but the longer and more complex the password is, the better protected your PDF will be.

3View and download

Once you enter the password and confirm that this password is the one you want to be set in order for others to be able to access your PDF, you can download the protected file to your computer and view it in your browser. We can also email you a link to your file, which will only be valid for 24 hours.

Higher encryption levels ensure higher protection

There are different levels and types of encryption that exist. The strongest and most secure level of encryption within PDF format is 256-bit AES (for Advanced Encryption Standard), which has never been cracked! This guarantees that your file will be under the best protection available – so long as you don’t forget your password. PDF format previously allowed for 128-bit AES encryption, but it is no longer supported by the newer PDF 2.0 format.
