How to Autofill PDF forms on iPhone, iPad and Mac

Earlier limited to the Safari app, Apple’s enhanced AutoFill feature has now branched out to PDF files across the system. Unlike Safari, there isn’t a specific setting you need to enable. All you need to do is ensure you have upgraded to iOS 17.2, iPadOS 17.2, or macOS Sonoma 14.2.

In this guide, I’ll show how you can use Apple’s enhanced AutoFill to automatically enter basic details in PDF files. But before delving into the process, let’s take a quick look at how this feature works.

How does AutoFill work on Apple devices?

Enhanced AutoFill in PDFs was first announced at WWDC 23, and after a long wait, this feature is now available for everyone. Using this feature, users can fill in basic contact information in PDF files with just a few taps.

The in-built machine learning algorithms of enhanced AutoFill recognize patterns and sections in a PDF. Based on the analysis, it suggests relevant saved information on iPhone, iPad, and Mac.

Users can simply tap on a form field or input area, and the device will display suggested content that is likely apt for the field.

Apple’s enhanced AutoFill can save time and reduce the chance of mistakes by eliminating the need to manually type repetitive information such as names, addresses, or phone numbers each time they are required.

Further, you can trust Apple’s privacy policy. None of your information is locally stored on the device. So, there’s no need to be wary of data breaches or unauthorized access.

One must also note that there is no way of enabling or disabling enhanced AutoFill in PDFs. It is a default, native feature.

If you’re also tired of manually filling out PDF documents and forms like me, then here’s how you can use enhanced AutoFill to do this job on Apple devices.

While this idea sounds intriguing, there are a set of steps you must take to get the most out of AutoFill on iPhone, iPad, and Mac.

How to set up My Card in Contacts app

To being using Apple’s enhanced AutoFull, you must fill in your details on My Card.

These details will be fetched by AutoFill whenever you edit a PDF. Here’s what you must do.

Note: Skip this section if you’ve already set up My Card on your device.

1. Launch the Phone app → Go to Contacts.
2. Tap My Card → Choose Edit.
3. Now, fill in your details as asked for in the dedicated section.
   The more information you can provide, the better.
4. Once ready, tap Done from the top-right corner.
   
   

Mac users: If your devices are running with the same Apple ID, you’re covered. If not, head to the Contacts app → Your profile → Edit.

Now that your My Card is all set, it’s time to begin with enhanced AutoFill.
