Can I save two different versions of the same photo on MacBook Pro?

How can I save two different versions of the same photo on MacBook Pro (Catalina)? One would be resized (not cropped, I mean resized in terms of pixels - in the Preview/Tools menu) and one original. Currently if I create a duplicate and edit one, the other is automatically edited the same way. I've seen answers to this question dated 6 or 7 years ago, but the software has changed since then and the answers no longer seem to apply. Thanks for any help.
