If you want to encrypt PDF on a Mac, the easiest method is to use the Application overview. You can use Preview to add a password to your most sensitive PDF documents to keep them secure.
The preview is available as the main macOS application. So you will find it on any Mac computer. No additional software is required: all you need is a PDF document to encrypt and a Mac to encrypt it.
If you prefer to use other software, you can Password-protected PDFs using Microsoft Office instead, but Preview offers the quickest way to do it using a main Mac app.
To add a password to a PDF document on macOS, open the Preview application from the Launchpad, which you can launch from the Dock at the bottom of your Mac screen.
You can also launch the preview from the Applications folder in the Finder application. You will also find it as an icon on your Dock.
Once the preview is open, click File> Open in the menu bar to open the PDF document that you want to encrypt with a password.
Open to open a PDF in the preview “width =” 421 “height =” 247 “onload =” pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon (this); “onerror =” this.onerror = null; pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon (this); “/>
To start encrypting the PDF document you opened in Preview, click File> Export from the menu bar.
Export in the preview to start adding a password “width =” 473 “height =” 462 “onload =” pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon (this); “onerror =” this.onerror = null; pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon (this); “/>
This will bring up various options for exporting your PDF to different formats, including the option to add a password.
If you do not want to overwrite your existing document, you will need to give a name to your new document in the “Export As” box. Confirm the storage location in the “Where” drop-down menu.
To add a password, check the “Encrypt” box in the options menu, then type a secure password in the “Password” and “Verify” boxes immediately below.
Press the “Save” button to save your encrypted PDF document once you have confirmed your settings.
Your PDF document will then be exported using the options you have selected. To load the document into Preview after the file has been encrypted, you will need to enter a password.
Type the document password in the “Password” box and then press Enter on your keyboard.
If the password is correct, it will decrypt the file and open the document. You will be able to continue viewing the file until you close it. Once closed, you will need to re-enter the password to view the file again.
