Once you know how to sign documents directly on your iPhone, you can eliminate extra trips to the post office or print shop just for paperwork. Managing contracts, legal forms, applications—all that flow requiring authorization—gets much more efficient.
This guide covers 2 methods to sign sheets: one operates online, and the other works completely offline.
Option 1. PDF Candy
PDF Candy delivers rapid and reliable performance for on-the-go contract approval, directly from your iPhone. The system accommodates multiple formats, offering a way to sign PDF online for free as a streamlined alternate to handwritten ones. Its user interface is intuitive, with minimal learning curve required.
How to sign your documents on iPhone online
- If your file is already saved in a portable type and you just want to add signature to PDF, proceed. For Word or other extensions, first transform it into a PDF with an online converter.
- Launch the Sign PDF service and click the "Add file" button to upload your material.
- After, select "New signature" at the top of the screen. You can draw it, type your name, or insert an image containing it.
- Adjust the autograph’s position and size as needed on the page.
- Once everything looks correct, tap "Export file". The signed version is then saved instantly as a PDF.
Relying on this online solution with your iPhone brings several advantages. You can download the finalized archive, upload it to a cloud platform, or create a shareable link.
By accessing your account, it’s possible to complete signatures while traveling and later retrieve the output on another device. If adjustments are needed, the online PDF editor helps you quickly fix errors or update content.
Best for:
- Freelance Consultants – Approve agreements while traveling or meeting clients.
- Real Estate Brokers – Sign property documents without needing printed copies.
- Event Planners – Finalize contracts or permits directly from a mobile device.
Option 2. Sign all documents on iPhone using Markup
You can insert a signature into PDFs and other extensions with Markup. This integrated feature combines annotation and drawing instruments, enabling to modify images, screenshots, and various publications on iOS devices.
Your iPhone already includes all necessary tools. Simply open the doc in an utility compatible with Markup (Files, Mail, Messages, or Photos). Below are detailed instructions for each case.
Messages and Mail
- Run the papers and tap the Markup icon in the bottom-right corner.
- Click "+" and select "Signature".
- Pick a stored mark or create a fresh one.
- Place it in the desired spot and tap "Done".
Files
- Locate the needed material in the platform and long-press its preview.
- Hit "Quick Actions" and pick Markup.
- Select "+", then "Signature" to apply your sign-off.
- Adjust size, reposition if required, and confirm with "Done".
Photos
- Open the scan of your document, tap "Edit", and then the Markup thumbnail in the top-right corner.
- Choose "+" followed by "Signature".
- Draw or employ a saved version and drag it onto the page. Resize if needed.
- Once finished, click "Done" and save the update.
Markup on iPhone really streamlines digital signing. You can leave your autographs for fast reuse—no more hassle of redrawing it every single time. All your signed papers sync automatically through iCloud, so you get instant access on any Apple device you own.
Still, there is a limitation. Some formats may not support Markup. In such cases, a free PDF converter can turn the item into PDF, which then would be available for online document signing or directly within Markup.
Best for:
- Educators – Authorize permission slips, curriculum approvals, or feedback forms.
- Healthcare Administrators – Endorse patient records or internal forms securely.
- Reporters – Sign releases or approvals for publications on the go.
Security measures
Signing documents on an iPhone can remain protected when proper precautions are observed.
- PDF Candy deletes all uploaded content from its servers after two hours, providing an extra layer of protection and maintaining privacy during the signing process.
- Markup functions entirely on the gadget, so materials and signatures are never transmitted online or stored externally. This reduces the risk of exposing confidential information.
Additionally, secure your iPhone with a strong passcode, Touch ID, or Face ID to block unauthorized access to the device and saved files. You can also make a hidden album in the Photos app to maintain selected scans or images separate from the main gallery, further safeguarding sensitive data.
Tips for creating a professional PDF signature
- Use a stylus or Apple pencil: These tools offer precise control, so your lines won’t look jagged or off.
- Simplicity is key: Skip elaborate flourishes—clear and straightforward endorsements are easier to replicate and recognize.
- Prioritize legibility: Your signature needs to be distinct and consistently identifiable across all documents.
- Stick to the same format: Maintain uniformity when applying your mark to different PDFs for a professional appearance.
- Watch the size: Your identifier should fit the layout—visible, but not oversized or overpowering.
- High contrast is non-negotiable: Go with dark ink on a light background to ensure your autograph displays clearly on both digital and printed materials.
- Verify across devices: Test your signature on multiple gadgets, including mobile and desktop, to catch any issues early.
- Leave a master copy: Keep an original, high-resolution copy of your endorsement stored safely. This allows for quick deployment on new archives without sacrificing quality over time.
