How to sign a document on an iPhone

Signing a document on an iPhone is a straightforward process.

You have several options, depending on the format of the document (PDF, Word, image, etc.) and whether it is saved to your phone or you have received it as an email attachment. 

Many people opt to use the iOS Mail app because it comes pre-installed on all iPhones. Gmail also has signing features. Apps like Adobe Acrobat and PandaDoc provide users with more functionality.

If you regularly deal with large volumes of documents, an advanced platform like PandaDoc, which provides in-depth tracking, signature certificates, and storage features, will likely be preferable. 

Here are the most common ways of signing a document on an iPhone:

  • Sign email attachments directly in the iOS Mail app – This method is suitable for people that want to add a signature to a document without making any further changes. 
  • Sign email attachments using the Gmail app – If you use Gmail on your iPhone, you can sign using in-app tools. 
  • Sign with Adobe Acrobat for iPhone – You can download PDFs and sign them using the Adobe Acrobat app for iPhone. The benefit of this method is that it provides additional features for amending documents (such as adding notes). 
  • Sign with a document management app like PandaDoc – Using a document management app provides advanced functionality. You can save files, send documents to clients for signing, and track recipient activity, among other things. 

Let’s look at each of these methods in more depth. 

Sign using the iOS Mail app

If you received a document as an email attachment, you can open and approve it in the iOS Mail app. 

Follow the steps below to sign a document using the Mail app:

1. Open the attachment in the Mail app so you see a full preview. You may need to download it if it is an image file or scanned PDF document. 

2. Select the Markup icon in the top right of the screen.
