You're on the move-closing a deal from a coffee shop, approving a proposal from the airport, or onboarding a new client while out of the office.
Suddenly, a critical document lands in your inbox, and it needs your signature. Yesterday, this meant a frantic search for a printer and scanner. Today, your iPhone or iPad is all you need.
The ability to sign documents electronically from your Apple device isn't just a convenience; it's a fundamental requirement for modern business.
But not all mobile signatures are created equal. While your iPhone has built-in tools, they may not offer the security, legality, and professionalism your business demands.
This guide explores how to create and use electronic signatures on your iPhone and iPad, distinguishing between basic methods and professional-grade solutions that protect your agreements and accelerate your workflow.
Key Takeaways
- 📱 Two Main Methods: You can sign documents on an iPhone or iPad using Apple's built-in Markup tool or a dedicated electronic signature platform like eSignly.
- ⚖️ Business vs. Casual Use: Markup is suitable for casual, low-risk situations. However, for business agreements, a dedicated platform is essential as it provides a legally binding audit trail, enhanced security, and compliance with laws like the ESIGN Act.
- 🔐 Security is Paramount: Professional eSignature solutions offer robust security features, including encryption and detailed logs of who signed, when, and where. This level of verification is absent in basic tools.
- 🚀 Streamline Your Workflow: Using a platform like eSignly allows you to not only sign but also request signatures, create templates, and track document status, all from your mobile device, saving significant time and effort.
The Built-in Way: Using Apple's Markup Tool (And Its Limitations)
Apple provides a convenient, built-in feature called Markup that allows you to draw your signature on PDFs and images directly within apps like Mail, Files, and Photos.
It's quick, easy, and already on your device.
How to Sign a PDF or Image with Markup
- Open the PDF attachment in the Mail app or a document in the Files app.
- Tap the Markup icon (it looks like a pen tip in a circle).
- In the Markup toolbar that appears at the bottom, tap the '+' button and select 'Signature'.
- If you've saved a signature before, you can select it. If not, you can draw a new one with your finger or an Apple Pencil.
- Drag and resize your signature to place it on the document.
- Tap 'Done' to save the signed document.
Why Markup Isn't Enough for Business Documents
While Markup is fine for signing a permission slip or annotating a photo, it falls critically short for professional use.
The signature created is essentially just an image placed on a document. Here's why that's a problem:
- Lack of an Audit Trail: There is no verifiable record of when the document was signed, by whom, or from what location and IP address. This makes it difficult to defend in a legal dispute.
- Questionable Legal Standing: Without the robust evidence provided by an audit trail, the signature's intent and authenticity can be easily challenged. For important contracts, this risk is unacceptable.
- No Advanced Security: The document itself isn't secured or tamper-sealed after signing. Anyone with basic PDF editing software could potentially alter the document after the fact.
- Inefficient for Workflows: Markup is a one-off tool. You can't use it to request signatures from others, track progress, send reminders, or create reusable templates.

Are Electronic Signatures Created on an iPhone Legally Binding?
This is the most critical question, and the answer is a resounding yes, provided you use the right tool. In the United States, the Electronic Signatures in Global and National Commerce (ESIGN) Act of 2000 and the Uniform Electronic Transactions Act (UETA) give electronic signatures the same legal status as handwritten ones.
For SMBs and enterprises alike, this is a game-changer.
However, for a signature to be legally enforceable, it must meet certain criteria:
- Intent to Sign: The signer must demonstrate a clear intention to sign the agreement.
- Consent to Do Business Electronically: Users must consent to conducting the transaction electronically.
- Record Retention: The signed document must be stored and accurately reproduced.
- Association of Signature with the Record: The system must link the signature to the document.
A platform like eSignly is built to satisfy these requirements automatically. The detailed audit trail captures the entire signing process, providing robust proof of intent and consent, ensuring your agreements hold up under scrutiny.
This is a key reason why knowing what electronic signatures are and how to use them properly is so important for business.
2025 Update: The Future of Mobile Signatures is Secure and Seamless
As we move forward, the reliance on mobile devices for business-critical operations will only intensify. The trend is shifting from simply signing on a phone to managing entire agreement workflows.
In 2025 and beyond, expect to see even tighter integration with mobile-native features. For instance, using your iPhone's Face ID or Touch ID can provide an additional layer of signer authentication, making the process both faster and more secure.
The expectation is no longer just about function but about experience. Signers expect a clean, fast, and intuitive process on their mobile devices without pinching, zooming, or rotating their screens.
Platforms that prioritize a mobile-first design will continue to lead the market, ensuring that business never has to stop, no matter where you are.
Choosing the Right eSignature Solution for Your Apple Devices
When selecting a platform, it's essential to look beyond just the signature. Here is a checklist of key features to consider for a truly mobile-friendly workflow:
- ✅ Responsive Design: Does the platform work flawlessly in a mobile browser without requiring an app?
- ✅ Comprehensive Audit Trails: Does it provide a detailed, court-admissible log of every action?
- ✅ Bank-Grade Security: Is the platform compliant with major security standards like SOC 2 Type II and ISO 27001?
- ✅ Workflow Automation: Can you create templates, set signing orders, and send automated reminders?
- ✅ Easy for All Parties: Is the experience simple and intuitive for the person signing the document?
- ✅ Integration Capabilities: Can it connect with other tools you use, like cloud storage (Google Drive, Dropbox) or your CRM?
Ensuring your chosen solution ticks these boxes will empower you to conduct business securely and efficiently from your iPhone or iPad.
