When you are working in Photoshop CS5 to create images or designs for clients, you might find yourself working with images or information that need to be kept private. Whether the client is worried about someone else seeing the contents of the file, or you are worried that someone snooping around on your computer might see something they shouldn’t, the ability to secure a file is a nice option to have. Fortunately Photoshop CS5 has some options that allow you to protect your files, including the ability to add a password to your Photoshop file.
Password Protect a Photoshop PDF
Adding passwords to Photoshop PDFs is something that can be done on a per-file basis, so it is not a setting that you will constantly need to be enabling and disabling every time you run Photoshop CS5. So continue reading below to learn how to add a password to an individual PDF file in Photoshop.
Step 1: Open the PDF file in Photoshop that you want to protect with a password.
Step 2: Click File at the top of the window, then click the Save As option.
Step 3: Type a name for the file into the File name field.
Step 4: Click the drop-down menu to the right of Format, click the Photoshop PDF option, then click the Save button.
Step 5: Click Security at the left side of the window.
Step 6: Check the box to the left of Require a password to open the document.
Step 7: Type your password into the field to the right of Document Open Password, then click the Save PDF button at the bottom of the window.
Step 8: Re-type the password into the Confirm password field, then click the OK button.
