Signing a PDF document on your iPhone can be a convenient way to add your signature to important files without the need for printing and scanning. With the right tools and apps, you can easily sign PDFs directly on your iPhone. In this tutorial, we will guide you through the process of signing a PDF document on your iPhone.

Step 1: Install an App for Signing PDFs

To sign a PDF document on your iPhone, you will need to install a reliable app that supports this functionality. There are several apps available on the App Store, such as Adobe Acrobat Reader, DocuSign, and SignEasy. Choose one that suits your needs and install it on your device.

Step 2: Open the PDF Document

Once you have installed the app, open it and locate the PDF document that you want to sign. You can either import the file from cloud storage services like iCloud or Dropbox or browse through your local files.

Step 3: Tap on the Signature Tool

After opening the PDF document in the app, look for a signature tool within the app’s interface. This tool is usually represented by an icon resembling a pen or pencil. Tap on it to access the signature options.

Step 4: Create Your Signature

To sign a PDF document, you have two options: creating a digital signature or using your finger to draw a signature directly on the screen.

  • Create a Digital Signature: Some apps allow you to create a digital signature by typing in your name and selecting a font style that resembles your actual signature. This option provides consistency across multiple documents.
  • Draw Your Signature: If you prefer to create a signature using your finger, select the option to draw your signature directly on the screen.

    The app will usually provide a canvas where you can draw your signature using your finger or a stylus. Take your time to ensure that your signature looks accurate and professional.

Step 5: Position and Resize Your Signature

Once you have created or drawn your signature, you can position and resize it within the PDF document. Most apps allow you to drag and drop the signature onto the desired location. Additionally, you can use pinch gestures to adjust the size of the signature so that it fits perfectly on the document.

Step 6: Save and Share Your Signed PDF

After positioning your signature, save the changes made to the PDF document. The app will typically provide an option to save the signed document directly within its interface. Once saved, you can share the signed PDF through email, messaging apps, or by uploading it to cloud storage services.


  • Use a Stylus: If you find it challenging to draw a signature accurately with your finger, consider using a stylus for better precision.
  • Practice Before Signing: If this is your first time signing a PDF on iPhone or using a particular app, practice creating your signature on a blank page before signing an important document.
  • Verify Your Signature: After signing a document, double-check if everything looks correct before sharing it with others. Ensure that there are no extra marks or accidental smudges on the document.

Congratulations! You have successfully learned how to sign a PDF document on your iPhone. By following these steps, you can now conveniently add your signature to important files directly from your iPhone, saving time and effort.
