Using your trackpad to create a signature
To use your trackpad or mouse to digitally create your signature:
- Press where it says Trackpad.
- Then tap Click Here to Begin and start signing with your mouse or trackpad. While a mouse might be more accurate, this option is a little sensitive and makes it a little trickier to recreate your signature as cleanly as you might want.
- Once you’ve created your signature, press any key, then click Done.
- Then click on your signature and hold it down while you use your trackpad to place it wherever you want on your document.
- If you want to resize it, drag the blue dots around the signature.
- When finished, click outside of the box surrounding your signature and save your document by clicking File in the upper left-hand corner of your screen and then scrolling down and clicking Save.
Using your camera to create a signature
For this option, you will have to pull out a piece of paper and a pen and sign your name on the piece of paper, or if you have a hard copy of the document with your signature already on it.
- First, press where it says Camera.
- Then tap Click Here to Begin
- Sign your name onto a white piece of paper, and then hold it up facing the camera so that your signature is level with the blue line in the window.
- When your signature appears in the window, click Done.
- Then click on your signature and hold it down while you use your trackpad to place it wherever you want on your document.
- If you want to resize it, drag the blue dots around the signature.
- When finished, click outside of the box surrounding your signature and save your document by clicking File in the upper left-hand corner of your screen and then scrolling down and clicking Save.

Using your iPhone or iPad to create a signature
If you have both a Mac and an iPhone or iPad, this might be the easiest option:
- If your devices are connected, when you select the iPhone or iPad option in Preview’s signature manager, your phone will display a box for you to sign with your finger. Go ahead and sign.
- Once you’ve signed your signature, then tap Done, and it will appear back on your Mac in Preview.
- Then click on your signature and hold it down while you use your trackpad to place it wherever you want on your document.
- If you want to resize it, drag the blue dots around the signature.
- When finished click outside of the box surrounding your signature and save your document by clicking File in the upper left-hand corner of your screen and then scrolling down and clicking Save.
Once you've created your signature on your iPhone, iPad or Mac, your new digital signature should be available across any of those devices that share the same Apple ID.
