Secondly, it speeds up the process of signing documents as you can do it anywhere and at any time. Whether you’re traveling or working from home, you can easily access your documents and sign them electronically using your Mac.

With the increasing popularity of remote working, electronic signatures are becoming more important than ever before. So, if you haven’t already, it’s time to start signing your documents on your Mac.

Use Preview to Sign Documents on Mac

If you own a Mac, there’s good news – you don’t need to install any additional software to sign documents. Preview is already embedded in your computer’s operating system. Here’s how it works:

1. Open the document you want to sign in Preview.

2. Click on the ‘Markup Toolbar’ in the top-right corner. A series of icons will appear.

3. Find the ‘Signature’ icon – it looks like a cursive ‘S’. Click on it to expand the options and select the ‘Create Signature’ button.

4. You can now sign the document using one of the following four methods:

– Trackpad: Use your finger to scribble your signature directly into the trackpad. Preview will automatically convert it into a digital signature.

– Camera: If you have a signature on paper, hold it up to your Mac’s camera so it can capture a photo. Then, use your mouse or trackpad to position and scale the signature before saving it.

– iPhone/iPad: If you have an iPhone or an iPad with iOS 11 or later, you can create a digital signature using the Markup feature in the built-in Notes app. Simply sign a blank note with your finger using the appropriate tool, then tap-and-drag the signature to position it. Save the note, and your signature will sync to your Mac via iCloud.

– File: If you have a pre-existing electronic signature saved as an image file, you can drag and drop it into the signature box.

5. Once you have a signature, click where you want it to appear in the document. Preview will automatically insert it, and you can resize or reposition it as needed.

6. If you need to sign more than one document, repeat steps 2-5 for each one.

7. Finally, save the document by clicking on ‘File’ in the menu bar and selecting ‘Export as PDF’. Make sure to save the file with a new name, so you don’t overwrite the original document.

In conclusion, Preview is a useful and simple tool that can help you sign documents on your Mac quickly and efficiently. With just a few clicks, you can add a signature, text, or date to any document, all without having to download any third-party software.

Sign Documents on Mac using Third-Party Apps

If you need to sign multiple documents or want access to advanced features, using third-party apps can be a good idea. Here are some of the popular apps you can use:

Adobe Acrobat

One of the most popular apps for signing documents, Adobe Acrobat, provides advanced features like document collaboration, signing with a digital ID, and cloud storage. With Adobe Acrobat, you can sign a document by choosing the “Fill & Sign” option, which will open a dialog box prompting you to upload the document. Once you have uploaded the document, you can add your signature by drawing it with your mouse or touchpad, uploading it from a file, or using your computer’s built-in camera to capture a picture of your signature. Once you have added your signature, you can save the document as a PDF file, and you are done!


Another popular app for signing documents is SignEasy. This app provides a straightforward user interface that makes it easy to sign and email documents.
