Step by Step Tutorial: How to Fill Out PDF on iPhone 15

Before we jump into the steps, let’s understand why you’d want to fill out a PDF on your iPhone 15. It’s all about convenience and efficiency. You might be on the move or away from your desk, and a digital solution is the way to go. Plus, with the iPhone 15’s advanced features, filling out a PDF is as simple as sending a text message.

Step 1: Open the PDF File

To start, find and open the PDF file you need to fill out on your iPhone 15.

When you receive a PDF via email or download it from a website, you can usually open it directly from the Mail app or your preferred web browser. Sometimes, a PDF file might be stored in your iCloud Drive or another cloud service like Dropbox. You can access these files through the Files app on your iPhone 15.

Step 2: Tap the Markup Icon

Once the PDF is open, look for the markup icon (it usually looks like a pen tip) and tap it to enter editing mode.

The markup icon can typically be found in the upper-right corner of the screen. If you’re having trouble finding it, ensure you’re using an app that supports PDF editing, like the built-in Files app or Adobe Acrobat Reader.

Step 3: Fill Out the PDF

With the markup tools available, you can fill out text fields, select options, and even add a signature if necessary.

Text fields can be tapped on to bring up the keyboard, allowing you to type directly into the PDF. For checkboxes or similar options, simply use the drawing tool to make your selection. If you need to sign the PDF, use the signature tool to draw your signature with your finger or Apple Pencil.

Step 4: Save or Share the Completed PDF

After filling out the PDF, save your changes or share the file directly from your iPhone 15.

Saving the changes often happens automatically when you exit the markup mode, but you can also look for a save or done button just to be sure. If you need to send the completed PDF to someone, use the share icon (usually represented by a square with an upward-pointing arrow) to email it or send it via messaging apps.

After following these steps, your PDF should be complete and ready to go. You’ve successfully filled out your form without needing a printer or scanner—congratulations!
