How to sign a PDF on Mac

Effortlessly Sign PDFs: A Comprehensive Guide for Mac and iOS

This guide explores various methods for securely signing PDFs on your Mac and iPhone/iPad, streamlining your workflow and eliminating the need for printing, signing, and scanning. I've been digitally signing PDFs for over two years, and I'll share my preferred techniques and tools.

Secure PDF Signing Options:

While macOS's Preview offers built-in signing capabilities, it presents security concerns due to signature storage within the app itself and limited editing features. For enhanced security and functionality, I recommend Nitro PDF Pro. This professional-grade PDF editor allows for several signature types:

• Standard Signature: Easily create and place a signature using your trackpad or mouse. Signatures can be saved for reuse within Nitro's library.

• Nitro Sign (Subscription Required): This adds a robust security layer. Only invited recipients can sign, and you can track signing progress. A 14-day free trial is available.

Beyond signing, Nitro PDF Pro provides extensive features like page reordering, document merging, redaction, OCR, and more.

Using Preview for Digital Signatures:

Preview, your Mac's default image viewer, offers a free, albeit less secure, signing method:

1. Open your PDF in Preview.
2. Access the Markup toolbar (pencil icon).
3. Click the signature icon, create a signature using your trackpad, and place it on the document.

Trackpad Signature Creation:

You can create and save signatures directly in Preview's signature manager for quick reuse:

1. Open Preview.
2. Go to Tools > Annotate > Signature > Manage Signatures.
3. Create your signature using the trackpad.

Using a Camera for Signatures:

Alternatively, scan your handwritten signature:

1. Open your PDF in Preview.
2. Go to Markup > Create Signature > Camera.
3. Capture your signature using your camera.

Signing PDFs in Mail:

Sign PDFs directly within the Mail app:

1. Compose a new email and drag your PDF into the message.
2. Click the dropdown arrow on the PDF and select "Markup."
3. Follow the Preview signing steps.

Inserting Signatures from External Files:

For enhanced security, save your signature as a separate image file (e.g., PNG) and paste it into your PDF.

Signing PDFs on iPhone and iPad:

iOS's built-in Markup feature allows for PDF signing within the Files or Mail apps:

1. Open your PDF in Files or Mail.
2. Tap the Markup icon (pencil).
3. Tap the " " button > Signature.
4. Draw your signature.

Nitro PDF Pro on iOS offers similar functionality, including Nitro Sign for enhanced security.

Recommended Tools:

Nitro PDF Pro is a powerful and versatile option for all your PDF needs. Consider using PDF Squeezer for compressing signed PDFs and PDF Search for efficient document searching.
