Sign documents quickly and easily on your iPhone using pdfFiller's intuitive interface.

What is the Signature Tool?

The Signature tool in pdfFiller allows you to sign documents digitally on your iPhone. It is important to understand the distinction between self-signing and sending documents for signature. You can access the Signature tool via the Signature button in the main editor toolbar. This tool offers three methods for signing: Draw, Type, and Upload. Each method provides a unique way to create your signature, ensuring that you can choose the best option for your needs.

How Does Signing Work on iPhone?

Signing documents on your iPhone is essential for small and medium businesses that require efficient document workflows. Digital signatures are becoming increasingly important in various scenarios, such as signing contracts or authorizing leases. The benefits of mobile signing include the ability to sign documents from anywhere, eliminating the need for printing or scanning. This flexibility allows you to maintain productivity while ensuring that your documents are signed quickly and securely.

Three Ways to Create Your Signature

You can sign documents using your iPhone in three different ways: Draw, Type, and Upload. Each method produces a legally binding digital signature. The Draw method allows you to create a signature by hand, which is ideal for those who prefer a personal touch. The Type method enables you to select a font style and color, making it easy to create a signature that fits your brand. Lastly, the Upload method allows you to upload an image of your handwritten signature, providing a quick and convenient option for those who already have a signature image ready.

How to Draw Your Signature

Open the Signature tool in pdfFiller on your iPhone.
Select the Draw option to create your signature.
Use your finger, stylus, or touchpad to draw your signature.
Adjust the color and line thickness for your signature.
Resize and reposition your signature as needed.

How to Type Your Signature

Access the Signature tool and choose the Type option.
Type your name in the provided text box.
Select your preferred font style and color.
Place your typed signature in the desired location on the document.

How to Upload Your Signature Image

Open the Signature tool and select the Upload option.
Choose an image file of your handwritten signature from your device.
Ensure the image is clear and of high quality for best results.
Adjust the size and position of the uploaded signature on the document.

How to Add Your Initials

To add initials on your iPhone, you can use the same three methods: Draw, Type, or Upload. Each method allows you to create and place your initials wherever necessary in the document. You can resize and reposition your initials just like your signature, ensuring they fit perfectly in the designated areas.

Customizing Your Signature

You can customize your signature on your iPhone by adjusting the color and thickness of the drawn signature. When typing your signature, you can choose from various font styles and colors to match your preferences. Additionally, you can resize and reposition your signature to ensure it fits well within the document layout.

Saving and Reusing Your Signatures

To save your signature on your iPhone, simply follow the prompts in the Signature tool after creating your signature. You can set a default signature for future use, making it easier to sign documents quickly. Reusing your saved signatures streamlines the signing process, allowing you to focus on other important tasks.

Legal Validity of Signatures

Legally binding signatures on your iPhone comply with ESIGN, UETA, eIDAS, and GDPR regulations. This compliance ensures that your signed documents are valid and enforceable. Additionally, pdfFiller generates a timestamped audit trail for each signed document, providing an extra layer of security and verification. The Verified by pdfFiller badge further confirms the authenticity of your digital signature.

Scenarios for Signing on iPhone

There are several practical scenarios where you might need to sign documents on your iPhone. For instance, signing a lease agreement can be done quickly and securely without the need for physical paperwork. You can also authorize a contract directly from your mobile device, ensuring that important agreements are finalized promptly. Completing forms digitally on your iPhone allows for a more efficient workflow, especially for small businesses that rely on timely document processing.

Browser and Device Compatibility

Your iPhone is compatible with various browsers, ensuring that you can access pdfFiller's Signature tool without issues. The mobile app is also available, providing a user-friendly experience for signing documents on the go. Cross-device functionality allows you to start signing on one device and continue on another, enhancing your flexibility.
