Alternatively, if you already have Preview open, select File > Open and browse for the file. Choose the PDF and pick Open.
Step 2: Select Markup in the Preview toolbar at the top. This displays a bar for the Markup tools.
Step 3: Use the drop-down arrow next to the Sign button to choose your signature.
Step 4: When your signature displays, drag it to the spot where you want it in the document. You can also drag a corner to resize the signature to fit the document if needed.
You can then save the PDF, export it, or share it using File in the menu bar.
Create a signature and sign your PDF in Preview
If you don’t yet have a signature, you can create one to sign your document easily in Preview. Your new signature will automatically save so that you can reuse it in Preview later.
Step 1: Open your PDF in Preview, and select Markup in the toolbar.
Step 2: Use the drop-down arrow next to the Sign button to choose Create signature.
Step 3: You can then create your signature using your trackpad, camera, iPhone, or iPad. Here are the instructions for each option:
Tackpad: Select Trackpad to sign your name using your Mac’s trackpad, and choose Click here to begin. Use your finger to sign your name on the trackpad.
Camera: Select Camera to capture an image of your signature from a physical paper. Use a white piece of paper and sign your name. Then, hold the paper up to your camera so that your signature is even with the blue line on the screen.
iPhone or iPad: Select iPhone or iPad > Select device in the Preview window, and pick your iPhone or iPad from the list. You’ll then see a screen appear on your mobile device ready for your signature. Create the signature, and tap Done.
Step 4: With each of the above methods, you can use the Description box to describe the signature. You can also select Clear if you want to redo the signature.
Select Done when you finish.
Step 5: When you see the signature display in Preview using one of the above options, you can then drag to move it where needed in the document. Again, you can drag a corner to resize your signature.
Next, you can save, export, or share the signed PDF using File in the menu bar.
