I want to add my signature to PDFs in Preview, but the Trackpad/Camera method is terrible.

Any way to add a scanned signature to Preview??

The camera capture method works just fine, so long as you get the basics right.

  • Write your signature in black on a sheet of clean white paper.
  • Take your MacBook, camera etc over to the window, facing inwards.
  • Hold paper, now in daylight, to camera.
  • Done.

If the lighting is bad, the result will be bad.


sadly the only ways to add a signature in Preview, is by using the two different ways you mentioned. You could type your name in pages, print it out and use the camera.


Ok, for those who don't have a trackpad, and who also think the camera "scanned" signature looks crappy: Open up a random PDF in the Mail app on your iPhone or iPad, press the mark up icon on the top left, then the + icon on the bottom right, then signature. Create your signature here. It is then synced to all of your devices for use.
