2. How to Add Digital Signature to PDF

Aside from this, you can also digitally sign your business dealings, contracts, or any other PDF with a digital ID by utilizing UPDF for iOS. This will enable you to enter a paperless, sustainable world. Note that you must first add a digital signature field to the PDF using UPDF for Windows or Mac. Let's hop onto the steps.

Step 1. Open a PDF that contains a digital signature field in UPDF.

Step 2. Once opened, tap on the digital signature field.

Step 3. A new window will show up with the '+ Configure New Digital ID' and 'Continue' options at the bottom.

Step 3a. To create a new digital ID, tap on the '+ Configure New Digital ID' button. UPDF will display an interface prompting you to enter the identity information for creating the self-signed Digital ID, including your name, email address, organization unit (optional), and organization name (optional).

Step 3b. To sign with an existing digital ID, simply choose the desired one - UPDF will allow you to view the details of the selected digital ID. If this is the one you wish to use, tap on the Continue button. In the 'Sign as ...' interface, you can then choose its appearance from the two options provided: Standard Text and Creation Date.

Alternatively, you can select the Create option to reveal more customizations as shown below:

You can change Appearance or switch to the image section to upload an image.
Below, you can decide what you want to include in your digital signature. You have the following parameters in the Include Text drop-down menu that can be checked and marked for inclusion: Name, Date, Location, Reason, Logo, Labels, and Distinguished Name.
You can also alter the Text direction, make it left-aligned or right-aligned, or leave it to be automatic.
Lastly, you may Enter your Present Name.
If you want to reverse all your changes, click the None option. Otherwise, hit Save.

Step 4. Choose either option mentioned in step 3 to add a digital signature to your PDF. UPDF will then prompt you to save a copy of your file on the device at your desired location. Save it.

You have added your digital signature!
