How to Sign a PDF on iPhone

Signing PDF documents on your iPhone can be a convenient and time-saving process. Whether you need to sign a contract, fill out a form, or add your signature to an important document, the iPhone offers a simple and efficient solution. In this tutorial, we will guide you through the steps of signing a PDF on your iPhone.

Step 1: Download a PDF Signing App

If you don’t already have a PDF signing app installed on your iPhone, you will need to download one from the App Store. There are several great options available, such as Adobe Acrobat Reader, SignEasy, and DocuSign. Choose the app that best suits your needs and install it on your device.

Step 2: Open the PDF Document

Once you have installed the PDF signing app, locate the PDF document that you want to sign. You can find it in your email attachments or file management apps like iCloud Drive or Google Drive. Tap on the document to open it in the PDF signing app.

Step 3: Locate the Signature Tool

Most PDF signing apps provide a dedicated signature tool that allows you to add your signature effortlessly. Look for an icon or menu option labeled “Signature” or “Sign Document.” Tap on it to access the signature tool.

Step 4: Create Your Signature

In the signature tool, you will typically find options for creating and managing your signature. Depending on the app, you may be able to draw your signature using your finger or stylus directly on the screen, import an existing image of your signature from your photo library, or use pre-defined fonts to generate an electronic signature.


Make sure your signature is legible and resembles your handwritten signature to ensure its authenticity.

Step 5: Add Your Signature to the PDF

Once you have created or imported your signature, position it in the appropriate place on the PDF document. You can usually resize and adjust the orientation of the signature using pinch gestures or on-screen controls. Take care to align the signature accurately with any designated signature lines or boxes on the document.

Step 6: Save and Share

After adding your signature, review the entire document to ensure that it is complete and accurate. If everything looks good, save the signed PDF to your device or cloud storage service. You can then share it via email, messaging apps, or upload it to a file sharing platform.


In conclusion, signing a PDF on your iPhone is a straightforward process when using a dedicated PDF signing app. By following these six steps, you can easily add your electronic signature to any PDF document. Enjoy the convenience and efficiency of signing documents right from your iPhone!
