But don’t worry; in this article, we’ll explain  five ways you can sign documents with an iPhone, including:

  • Using Apple Markup
  • Using an electronic signature software
  • How to sign Microsoft Word documents
  • How to sign PDF documents
  • How to sign scanned documents

After reading all of this, you should be able to easily sign any digital document right from your iPhone.

Ready to get into it? Let’s begin.

How to Sign Any Document on an iPhone

Signing a document fast is important for streamlining your digital signage workflow. You may need to deal with a variety of forms, contracts, and agreements that require your online signature.

Below, we’ve outlined two strategies you can use to sign any type of document from the convenience of your iPhone. 

Use Apple Markup

Markup is an iPhone feature that lets you annotate and edit various documents like PDFs, images, and screenshots. With Markup, you can add your online signature — text or drawn — to a document.

The Markup feature is easy to use. Just follow these simple steps:

1. Open the Mail App

Start by opening the Mail app, as this is where you’ll be using the Markup feature. It syncs right into the email interface, so the process isn’t all that complicated. 

2. Choose to Reply to an Email or Compose a New One

After opening the app, decide whether you’re responding to an email you’ve received, or sending a new one out. Either way is fine, as it’s simply a matter of attaching your document to the email in question. The Markup feature will allow you to attach your digital signature to the document.

3. Add Your Signature to the Document

To add your digital signature to your document, start by tapping the body of your email. After doing so, tap the cursor, and select “Insert Photo or Video Attachment.” Scroll through the options, and look for the document button: find the PDF document you want to sign.

Once you’ve identified the PDF document, tap it, and tap the left arrow button. Then, tap the “Markup” button, and press the plus symbol to add your digital signature to the document. 

You can decide whether you want to type your signature or draw it. You can also add additional information if the document requires it.  

Use an Electronic Signature Software

Another great way to sign documents online is to use what’s known as “electronic signature software.” This is an application that allows you to easily sign digital documents, streamlining your signage workflow.

An electronic signature tool is a great option if you’re dealing with very large amounts of documents frequently. For larger businesses and organizations, this might be a better option because of all the extra features.

How to Sign a PDF Document on iPhone

When it comes to signing documents online, most will typically be in PDF format. Given this, it’s important that you know how to sign them as effortlessly as possible. In fact, you don’t even need to leave your iPhone to do it. Here’s how it’s done. 

1. Open Your PDF Document

Begin by finding and opening the PDF file of the document you want to sign on your iPhone. This can be done in several different apps, including Files, iBooks, and Messages. If you intend to send the signed document in an email, you can use the Mail app.

2. Use the Markup Feature

Once you’ve successfully identified and opened your PDF file, use the Markup feature. Press the + symbol in the bottom right-hand corner, and add your signature. You can do it with a preexisting, saved signature, or you can create a new one.

Congratulations, your PDF document on your iPhone should now have your signature on it.

How to Sign a Scanned Document on an iPhone

Did you know that your iPhone can scan documents? It’s a feature that makes it easy to create a high-quality digital copy of a physical paper document. Not only that, but you can easily sign this document after scanning it. We’ll explain how.

1. Scan Your Document

The first step is to use the scan feature of your iPhone — it’s located within the “Notes” app. Start by creating a new note, press the camera button, and then press the scan documents icon.

Once you’ve done this, position your physical copy of the document within your iPhone’s camera. If you’re in auto mode, it should scan the document for you. If not, simply press the shutter button, and adjust the cropping boundaries. This should save a scanned image of your document.

2. Sign Your Document

Your scanned document should now appear as a note in your Notes app. Find it, press the share button, and select the markup icon. You’ll then need to tap the add button, then follow through by tapping the signature button.

You’ll be able to either create a new signature or add an existing one on your iPhone. Position it where you need to on the document, and then press done.


Congratulations! You should now be able to sign any document with the use of your iPhone. We outlined various strategies you could use, including:
