How to add a signature to Pages

The signature annotations in Preview are not actual image files and cannot be used outside of Preview. One can change the signature annotation color in Prevew by choosing a different markup border color (e.g. blue) while the annotation is selected.

Hopefully, you have removed any personal privacy information (including GPS location data) from that photo of your signature, because it will travel with the Pages document or exported Word documents.

This is how I do it in Preview 10.0:

1. Open a PDF file in Preview. Click the Markup button to reveal the Annotations toolbar.
2. Click the Sign button. A list of your saved signatures will appear.
3. Click a signature to put it in the PDF file. Move the signature to an area of the PDF document where the background is all white.
4. Press Cmd + Shift + 4. The cursor will change shape to a crosshair.
5. Drag the cursor over your handwriting. Release the mouse or track pad. A screenshot will be saved to the Desktop.
6. Select the screenshot on the Desktop and click Edit > Copy.
7. Click in the Pages document where you want your screenshot and paste the screenshot.

You can also skip step 3 above, and in step 5 drag the cursor over a saved signature in the list.

To the best of my knowledge, Pages doesn't have a signature function. You can press Command-P in your Pages document, then select Save to PDF. Open the pdf in Preview and add the signature.

I took a photo using my iPhone of my signature and store it in Photos.... when I need a signature in Pages, I drag and drop the photo of my signature into the Pages document as you would any photograph. I also have my signature saved in Preview and can click on it to place in a pdf.
