Whenever I take photos of my quilts, I take it into "photo" that comes with Windows 10 & 11. I click on "edit" to crop what I don't want, then save it. Then I click on the 3dots on the top left corner and it gives me the option to resize. I keep my photos under 1 gig or is it 1m but whatever size it is, it's what they allow on this site.
