Sign PDFs with TrackPad

Ever had to sign documents quickly and return them to a sender? No matter the type of document that you're trying to sign, if you can avoid a printing, then sign, then scan, and send back workflow, it's always appreciated. Mac OS X's Preview application has long allowed for digital signatures, but in Yosemite you can sign documents using the trackpad, too.

Create a Signature with your TrackPad

  • Step 1: Open PDF that you wish to sign in the Preview App.
  • Step 2: Click View
  • Step 3: Click Show Markup Toolbar (Command + Shift + A)
  • Step 4: Chose the Sign button in the tool bar that appears, then click "Create Signature"
  • Step 5: In the Signature popup that appears, choose the Trackpad option , and click the "Click here to begin" button.

Once in this mode, sign you name using your finger on the trackpad.

When you are done with your signature, press any key on the keyboard to exit editing mode, and then press the Done button in the popup to save the signature in Preview.

You can also get a signature without the trackpad. To do so, follow the same steps as above, but choose the Camera option in step 5. Create a physical signature using black ink on a white piece of paper (for best results), then hold this signature up to the iSight camera on your Mac.

Use your Signature

When you are ready to use the signature in your document, follow these steps:

  • Step 1: Click View.
  • Step 2: Click Show Markup Toolbar (Command + Shift + A ).
  • Step 3: Choose the Sign button, then click on one of the saved signatures that appears in the list.

Once you do this, you'll see the signature inserted into the document. You can then resize and move the signature around on the PDF to make it look just right and fit over the signature area of the document you're signing.

Don't forget you need to save the signature inside of the document using Command + S (or get advanced save options by pressing Option + Command + Shift + S to open the Save As... panel).
