Signing a document on Mac is a simple process that can be done using the built-in Preview app. With Preview, you can add your signature to any document, whether it’s a PDF, an image file, or even a Word document. In this tutorial, we will guide you through the steps to sign a document on Mac using Preview.

Step 1: Open the Document in Preview

To get started, locate the document that you want to sign on your Mac and double-click on it. The document will open in the default application, which is usually Preview for PDFs and image files.

Step 2: Access the Markup Toolbar

Once the document is open in Preview, click on “View” in the menu bar at the top of the screen. From the drop-down menu, select “Show Markup Toolbar”. Alternatively, you can use the keyboard shortcut Command + Shift + A to access the markup toolbar.

Step 3: Add Your Signature

With the markup toolbar now visible, click on the “Sign” button. This will open a sub-menu with options to create a signature.

If you have already added your signature before, you can select it from this sub-menu. Otherwise, choose “Create Signature”.

  • Note: If you have a trackpad or a Magic Mouse with Force Touch capabilities, you can also use your finger or stylus to draw your signature directly onto the trackpad or mouse.

Option 1: Use Your Trackpad or Mouse

If you choose to create a signature using your trackpad or mouse, click on “Trackpad” or “Mouse” from the sub-menu. A small window will appear with instructions guiding you to sign using your input device. Follow the instructions to sign your name, and then click “Done”.

Option 2: Use Your Mac’s Camera

If you prefer to use your Mac’s camera to capture your signature, select “Camera” from the sub-menu. A preview window will open, showing the live feed from your camera.

Hold a piece of paper with your signature up to the camera and align it within the guidelines. When your signature is properly aligned and captured, click “Done”.

Step 4: Place Your Signature

After creating or selecting your signature, it will appear as a movable image on your document. Click and drag the signature to position it wherever you want it to appear. You can also resize the signature by clicking on one of its corners and dragging.

Step 5: Save Your Document

Once you have placed your signature on the document, click on “File” in the menu bar and select “Save” or “Save As” to save your signed document. Choose a location on your Mac where you want to save the file and give it a name.


Signing a document on Mac using Preview is an easy and convenient process. With just a few simple steps, you can add your signature to any document, making it legally binding and professional-looking. Remember to save your signed document after placing your signature for future reference.

Now that you know how to sign a document on Mac using Preview, you can efficiently handle all your signing needs without having to print, sign manually, and scan documents.
