How to Sign a PDF on iPhone: A Step-by-Step Guide

    In this digital age, signing documents has become easier than ever thanks to the advancement of technology. With the help of your iPhone, you can now sign PDF documents on the go without the need for printing and scanning. In this article, we will guide you through the process of digitally signing a PDF document using your iPhone.

    Step 1: Accessing the PDF

    The first step is to access the PDF document that needs to be signed. This can be done by opening the document from an email attachment, downloading it from a website or cloud storage service, or receiving it through a messaging app.

    Step 2: Using Markup Tools

    Once you have opened the PDF document on your iPhone, you can use the built-in Markup tools to add your signature. To do this, tap on the Markup icon (it looks like a pen) at the top right corner of the screen. This will open up a toolbar with various annotation options.

    Step 3: Adding Your Signature

    To add your signature to the document, tap on the “+” icon in the Markup toolbar and select “Signature” from the options that appear. You will then be prompted to create a new signature by either drawing it with your finger or stylus or by selecting one that you have previously saved.

    Step 4: Placing Your Signature

    After creating or selecting your signature, you can place it anywhere within the PDF document by tapping and dragging it to the desired location. You can also resize and reposition your signature as needed to ensure it fits in properly.

    Step 5: Saving and Sharing

    Once you are satisfied with the placement of your signature, you can save the signed PDF document by tapping on the “Done” button at the top left corner of the screen. You will then have the option to share the signed document via email, messaging apps, or cloud storage services.


    Signing PDF documents on your iPhone is a convenient and efficient way to handle paperwork without having to deal with printing and scanning. By following these simple steps using Markup tools, you can sign documents quickly and securely right from your smartphone.
