Remove the background from an image
In the Preview app on your Mac, click the Show Markup Toolbar button  (if the Markup toolbar isn’t showing), then click the Instant Alpha button (or use the Touch Bar).
Drag over part of the background.
Preview selects the area you dragged over and any pixels adjacent to it that have the same colors.
To delete the selected area, press Delete.
To delete everything outside the selected area, choose Edit > Invert Selection, then press Delete.
Repeat steps  until you have the image you want.

Great tips. The single caveat is when you have a white object on a white background. For that single situation, there's little for it but to do it by hand. Sometimes, using the magic wand set to zero will get you close, and then you can turn on Quick Mask to paint out the rest.

See my masking suggestion for mugs here, at the bottom: https://community.zazzle.com/t5/general-zazzle-discussion/cover-photos-questions-comments/td-p/63324...

Best would be if Zazzle would allow us to download the product on transparency. 😞
